“The First Tasting of the Season”

There is one yearly event, however, that livens the whole place up: hatsu-nomikiri. Held sometime between June and September, this is an event in which the condition of each tank of sake brewed the previous season is sampled and checked.Sake breweries are usually fairly quiet in the summer. Except for the few large breweries where brewing continues all year, most places are dark and quiet and empty, as the brewers themselves have gone home for the summer. Traditionally, the brewing staff traveled great distances from their rural farmland homes to work at the kura (brewery), although today most places employ local people.

Until about 100 years ago, sake was brewed in cedar tanks with bamboo bindings. Gorgeous though they may be, such tanks are significantly less airtight than the solid enamel-lined steel tanks used today, there was a greater possibility that the sake had “gone south.”

This might mean one of several types of contamination, with the most common being “hi-ochi,” a condition that can arise in unpasteurized sake. Sake suffering the dreaded hi-ochi becomes cloudy and yeasty, with the various flavors going haywire to the extreme.

And, so, each summer, most commonly just after the rainy season, the toji would trek back to the kura. In front of a small gathering of insiders, the valve at the bottom of a tank would be opened, and a small stream of sake would be guided into a special tasting glass that allowed the fragrance to spread. This would first be offered to the owner of the brewery. After he gave the nod, the toji himself would sniff and assess. They would then proceed to the other tanks one by one, checking the condition of each in the kura.

This is precisely the situation, by the way, in which a traditional tasting cup, a 180 cc white porcelain tumbler with two blue concentric circles on the bottom, would be used. The blue circles on the white background allow one to easily assess the clarity of the sake.

Each tank brewed throughout the season will take on a short life of its own, and the way each matures in the tank over the several-month aging period will be slightly different. Some will seem more well-rounded and balanced, others more brash and immature. The flavor and fragrance will of course be slightly different for each as well. So one other reason for tasting from each tank is to determine in which order the tanks will be bottled and shipped, with the more mature-tasting tanks going first.

These days, the aforementioned enameled metal tanks are the norm, so that the worries of the past are not as much of a concern today. Still, the event takes place, with the toji and owner being joined by perhaps a few important sake dealers, and several “kanteikan”(professional tasters) from the prefecture’s sake research center, or a similar such organization. These sensei will record their opinions in detail, to be used by the brewery for internal reference only.

Things proceed much in the same way as the old days, with sake being drawn off from a valve at the bottom of the tank. The temperature is recorded, sometimes written in chalk on the ground or even on the tank itself. The number of the tank is recorded, and the sake brought to another room for a formal tasting in a more official setting.

The results of this exercise will also help determine how the blending of the various tanks will proceed. For example, blending tank #4 with tank #21 may create precisely the type of sake aimed for, based on the tasting notes. Other information, such as whether or not a sake will benefit from pasteurization or extended aging, can also be inferred.

Naturally, things are vastly different from kura to kura. For example, most places have already completed their hatsu-nomikiri by the end of July. Many kura in Akita Prefecture, however, gear up for the event in September. Also, as this is the first such tasting, traditionally kura would then check the condition of the sake several times after that.

However, this is not something to be done haphazardly. When the tank is opened and sake drawn off like that, there is the risk that this act in itself will allow contaminating bacteria into the tank. It must be performed carefully, with clean implements.

Today, however, there is great diversity in the methods of each brewery. Many places age their sake in bottles, not in tanks. Also, some breweries age their sake a full year or two (usually at low temperatures) before even considering shipping it. Although the condition of such sake will also be assessed from occasionally, the actual hatsu-nomikiri might not take place for a while.

Although the timing and logistics of the hatsu-nomikiri have evolved and are adapted to each brewery’s needs, the event takes place everywhere, with at least a bit of inter-kura fanfare.

Readers are likely aware that I publish another newsletter, Sake Industry News, thanks to the liberal use of ads in this publication. In every other issue of SIN, we publish an interview with a brewer that consists of ten questions about the brewing season. Last issue, we published such an interview with a brewer that was chock full of interesting insights. (To find out who, please subscribe to Sake Industry News! You’ll be glad you did!)

One of the questions we asked him was, “How was production volume this year compared to last year? Up, down or the same?” His answer was that it was about the same. However, he went on to say that due to COVID19, sales have slumped significantly.

“We may have to reduce volume over the next few years. We’ve already committed to our rice purchase for next year so we won’t be able to adjust until the year after. It’s really quite scary!” he continued.

Just how challenging this can be for sake brewers – and rice growers too – might not be evident to most people, so let’s look at it here.

Naturally, all sake brewers want stable businesses, and most want to grow their business as well. And naturally enough they need to balance supply and demand. If they run out of product, consumers will run to other producers. But if they make too much sake, more than can be reasonably sold, it runs the risk of getting old and suffering in quality. In truth, there a dozen ways to mitigate the problem of having too much sake on hand, but not letting the problem arise in the first place is better than any of them.

So balancing what they think they can sell with how much they produce is a big part of running a sake-brewing business. There is much to take into account: trends, plans, stock on hand, economic environments and more will all affect sales. But after assessing what they think they can sell and how much they need to brew, they order rice.

Bear in mind with very, very few exceptions sake brewers do not own rice fields or grow their own rice. And even among those that do, no brewer grows all the rice needed for a full year’s production. Instead, they order it from farmers, usually through agricultural cooperatives but sometimes by direct contract.

Rice-growing is a whole ‘nother industry in Japan, with its own challenges. Naturally, farmers want to grow as much as they are legally permitted, but also need to be able to sell that rice easily. And like sake brewing, that calls for a whole lot of planning. Rice is harvested in the fall, but planting begins in the spring, somewhere between March and June. Planning just what rice will be grown where, and, for many farmers, how much will be sake rice and how much eating rice or even rice for some other use must all be planned way in advance.

What that means is that sake breweries place rice orders in February or so for rice for the following fall. Remember, every year is different. It might be a bumper crop, but yields might be much lower than usual. And much can change between the time rice is ordered and the time it hits the market a year later. Lots of things might change. Like COVID, for example.

And that is what happened this year. Brewers looked at things like sales trends up until February, and made decisions on how much sake rice to order. But due to COVID, overall sake sales in March dropped about 13 percent, and some individual brewers saw drops of 40 and 50 percent of shipments in March and April. Naturally, this would drastically drop the amount of rice one would normally order, but the orders were already in.

Modifying those orders is not a simple thing. In fact, sometimes it is just not possible. So much goes into the planning of how much rice and which rice will be grown where that it simply cannot be changed quickly. If a field in which sake rice was grown all of a sudden is used for another agricultural product, it is very difficult to change it back to sake rice. It just doesn’t work that way.

Some might think that another solution would be, rather than ask a farmer to just grow another rice, instead just say, “cancel the order, and let the field be empty this year,” but apparently that is even worse.

So in many cases, the brewers will be stuck with the rice that was ordered, and that is why it is “quite scary” to our interviewed brewer.

In truth, there are a handful of potential solutions. The rice can be stored at cold temperatures and used later – but the energy costs are significant. The brewed sake can be made in such a way that it stands up to time in the bottle better, stored colder than normal to slow down maturation (at a cost, of course!) and sold later than originally planned. And then, if need be, the following year’s production can be planned around the surplus.

But the rice-growing industry might not be able to adapt as fast.

In truth, it is a fairly intricate problem involving several industries, and it also depends on the whims of nature and the economic environment. Just how it will pan out, of course, remains to be seen. Stay tuned!

So the problem is complicated. But the solution is the same: all of us need to drink more sake. If we can enjoy more sake and nudge demand up steadily in spite of all that is happening in these times, we are doing our part, and all that we can to help the sake industry.

Happy New Year! Happy New “Brewing” Year that is! Welcome to 2BY, or “The Year Reiwa 2 Brewing Year.”

We have calendar years that run from January 1 to December 31. And we have fiscal years that are more variable, but tend to run from April 1 of one year until March 31 of the next, especially in Japan. And, most relevant to us, we have Brewing Year, or Jozo Nendo, which runs from July 1 of one year until June 30 of the next. Here’s an explanation of why that exist as it does.

First of all, while Japan does relate to the fact that this is 2020, officially and traditionally it is called Reiwa 2, or the 2nd year of the era of Reiwa. So to go from Reiwa to western years, add 18 – this will do in a pinch. The Heisei era, which started in 1989, just ended in 2019 with the switch to the Reiwa era when the emperor had his son take over.

While most sake is best young, sometimes sake is aged by the kura before being released. And sometimes, we can see an indication of the year in which it was brewed. This should make it all simpler – provided we know how to read that information. The problem is that a given sake brewing season stretches across two calendar years.

Sake brewing starts in the fall of one year and ends in the spring of the next. So, if a sake were labeled only as year Heisei 39 (2018), it would be brewed in one given season if it were January of 2018, but be a completely different brewing season – with different rice, weather, and possibly even more – if it were October 2018. This difference could be likened to two totally different vintages in the wine world. So, we need a bit more detail.

This point did not escape the clever folks in the brewing industry needed a way to speak about the sake of one season, unencumbered by trivial details like how the rest of the world measures time. It also was a necessity from the viewpoint of the folks at the ministry of taxation, who also needed a more efficient way to tax kura on their output.

And so long ago they came up with the concept of the “Brewing Year,” or BY. Just like fiscal years can differ from calendar years, in Japan the Brewing Year runs from July 1 to June 30th of the following year. This, then, encompasses the entire brewing season of every brewer in the country in one clean 12-month period.

So, BY1 ran from July 1 2019 until June 30 2020. And sake brewed last fall and into this spring would be considered part of BY1. And, we have just entered into BY2. So, even though calendar year 2 (read: 2020) is half over, we just now started BY2.

Why do they use July? Why not October 1 (Sake Day!) or another day in the fall when brewing begins? Well, consider that there are various scales of operation. A tiny brewery might begin in November and finish in February. More common is starting in October and finishing in April. A very large brewer might start as early as August and run until the next June. And there are even one or two that brew all twelve months of the year.

Since production is focused on the coldest month of the year, January or so, brewing operations will expand in both directions from that point. So by starting in July and running to June, the industry can capture a single brewing season for all brewers, big or small. While it ain’t rocket science, it is at least somewhat clever.

How does this help us? Well, when we see a sake labeled, for example, H26BY, you know that since Heisei 26 is 2014, this sake was brewed in the season beginning in the fall of 2014, and running into the spring of 2015.

That would make it about a year to a year and a half since being brewed, just about right for much sake, if young by some mature sake standards.

Note, this is not on all bottles. It is common to talk about it with producers and other sake adherents, but the only time it is actually printed on a label is when the sake has been aged deliberately, and the brewer wants you to know just how long it has been aged. It is indispensable in those situations, since the date that must be printed in tiny characters in the corner of the label legally indicates about when it was shipped from the brewery, and that may not let us know just how long it was aged before that.

Again, since aged sake is such a small drop in the bucket, you will not see this so commonly. But if and when you see such mysterious nomenclature, you will know precisely how old your sake is.

Also known as “Awanashi Kobo”

Admittedly, the subject of yeast types begins to push the envelope of geekdom, ever-so-slightly encroaching into the realm where most folks’ interest in sake begins to wane. While some want to know both in theory and practice the difference between a Number 9 and a Number 10, and perhaps even between a CEL-24 and EK-1, most of us are content to sip and smile. Even so, there are some interesting historical, cultural and technical anecdotes surrounding even things as dryly scientific as yeast, making it well worth a look-see for those that like sake. The lore – dare I say subculture? – surrounding foamless yeasts, or “awanashi kobo,” is one such example.

First of all, just what is foamless yeast? Usually, when sake undergoes its 20- to 40-day fermentation, the foam rises in great swaths and falls again, especially over the first third or so of this period. Last month, we talked about the appearance of the foam, and how much brewers can deduce from watching it. You can read that here.

The sake brewers of olde would judge the stage, progress and condition of a given batch by the appearance (and smell, and taste, and even sound) of this foam topping. Many brewers simply prefer the foam, as it gives them one more source of all-important input that can be used in assessing the progress of a fermenting tank, and when a sake is ready to be pressed. The five senses are, after all, the most reliable tools of the sake-brewing craft.

Also, there are ten times more yeast cells in the foam than the mash itself, so very often yeast for subsequent batches is removed from the foam of healthy, vibrantly fermenting tanks.

So foamless yeasts, obviously, are strains of yeast that do yield bubbles and foam on the top of the moromi (fermenting mash) as they ferment away and convert sugars to alcohol, carbon dioxide, and more. (Actually, even foamless yeasts create a little bit of foam.) The question is, if brewers can learn so much from the appearance of this foam, then why would anyone want to use these foamless yeasts? There are, actually, a number of very good reasons. Most of these are centered around efficiency, sanitation, labor-savings, and even safety.

For instance, since the foam rises so high during fermentation, brewers cannot fill a tank to the brim with rice, koji and water since it would soon overflow with foam, leading to hygienic nightmare. Rather, they can only fill the tank initially about 3/4 of the way to leave room for the foam to rise and fall. Naturally, this puts a damper on one’s yields and efficiency. With foamless yeasts, however, this concern is all but a non-issue, and a brewery can get much higher yields out of each batch and tank, which contributes massively to the overall efficiency of a year’s worth of brewing.

Also, when foam does rise and fall, the remains that cling to the side of the tank are a veritable hotbed of bacterial activity, an orgy of undesirable microorganisms just hankerin’ to drop back in and do damage to the unsuspecting ambrosia-in-waiting below. So this must be assiduously cleaned off by the brewers. Not only is this hard and time-consuming work, it is also quite dangerous, since it generally requires leaning into the tank.

So by eliminating the foamy remains, time, labor, and risk are spared. Finally, without all that gunk in the way, the hard-working yeast cells move and work a bit more freely, so that fermentation proceeds a smidgeon faster and can finish a day or two earlier.

Why are they foamless? What happens, it seems, is that most yeast cells will cling to bubbles of carbon dioxide that are created and then rise to the surface. Foamless yeast cells, on the other hand, for whatever reason do not cling to these bubbles and so are not carried up, up, and away. Since the bubbles are unencumbered, they pop, and there is no foam rising high above the mash.

The foamless yeasts that are commonly encountered out there today are non-foaming versions of the “usual suspects,” rather than being new, unknown, or total mutant life-forms. Most of the foamless yeasts commonly seen used in sake these days are simply foamless versions of the main Brewing Society of Japan yeasts, i.e. Numbers 6, 7, 9, 10, 16 and lately 18 (which, actually, does not even have a foaming counterpart!). There are others, of course, but we just hear about them less often.

Actually, these too are naturally occurring. About one in every several hundred million yeast cells of a given type are foamless, but obviously, if just one in several hundred million is non-foaming, no one will notice. It just takes patience to isolate some and cultivate a pure culture of them.

Also, they have been around a long time, it seems, but proper records go back until only about 1916, when several breweries reported experiences with them. Apparently, until then, the brewers that encountered these thought, “ Whoa. This can’t be right. Let’s just quietly throw this mutant away before anyone finds out about it. It could be bad for our rep and all.”

But then in 1931, the Sake Research Center in Niigata successfully brewed a proper batch with foamless yeast. In 1963, based on some foamless yeast isolated at a brewery in Shimane making a sake called Hikami Masamune, researchers began to study it properly, and with the help of a local-to-Shimane famous sake professor named Yuichi Akiyama (that was until recently still active and famous), in 1971 the foamless version of Number 7 became available to brewers around the country.

However, the first commercial use of a foamless yeast was actually in Hawaii, believe it or not. That was in 1960 or 1961, a full ten years before it was used on anything remotely resembling a large scale in Japan, by Mr. Takao Nihei of the Honolulu Sake Brewery. Dispatched by the brewing research organization within the government of Japan, he was the first to take what information there was on these yeasts (and a sample, of course) and run with it. His focus was saving labor and producing great sake with great efficiency, and this he did with great success.

Are these foamless yeasts really the same as their bubbling counterparts, except for the foam? I mean, c’mon; really? I always take the opportunity to ask that question whenever I visit a brewery using foamless yeast, being sure to pretend it is the first time I have ever done so. Most of the time they would answer, “Yes, the results are essentially same, and the practical advantages make it a clear choice for us.” However, there are a still a few hardcore brewers who insist that the foamless manifestations are not quite as good as the foaming yeasts. Naturally, the ability to gather information from the appearance of the foam is eliminated. Still, most brewers feel that with foamless yeasts they get the same quality of sake, with less mess.

A final technical note for those that are interested: foamless yeasts, at least those distributed by the Brewing Society of Japan, are designated by a -01 after the normal nomenclature. So a foamless Number 7 is known as 701, foamless Number 9 as 901, and so on. Those you are likely to come across are 601, 701, 901, 10-01, 1601 and 1801 (for which there is no regular #18).

Take the time to look for the yeast used in your sake. Sure, it’s a bit maniacal, but fun as well. And if you see one of the numbers ending in -01 above, you know just what it is.

and what they tell you…

Sake brewing today has become very scientific. But long ago, before the days of thermometers, hydrometers, and barometers, brewers relied entirely on their five senses to gauge the progress of a fermenting tank of sake. As a curious side note, one toji told me that they compared the accuracy of some of the old school guys to that of modern instruments, and that the old toji of yesteryear were just as accurate as the modern equipment. Not sure this has been scientifically documented, but it is a great anecdote.

Although they might not have known the scientific causes for the phenomena they were observing, experience and intuition (there it is again!) told them how to interpret what they saw, tasted and smelled. One of the most reliable of these empirical yardsticks – and one that is still used today – is the appearance of the foam on the top of the moromi (fermenting mash).

Throughout the 18 to 35 day ferment, the foam will change appearance quite regularly, and very clearly reflect what is taking place inside the tank. Over the centuries, names were given to the foam at each stage that made it easy to assess and convey the status of the work in progress.

After the yeast starter has been created, and after the three additions of water, rice and koji over four days have been completed, foam will begin to develop as the yeast cells process the sugars in the tank, and give off carbon dioxide. This will rise to the surface, often still attached to the yeast cells. This is why the foam has two and a half times as many yeast cells in it as the liquid beneath.

Two or three days into the ferment, small striations will appear on the surface, similar to taught muscle under skin; hence the term suji-awa (fibrous foam). Next, a think layer of soft foam will begin to cover the entire tank; this is known as mizu-awa (water foam).

The timing of these changes of course depends on a myriad of factors, such as how much the rice has been milled, and the temperature of the tank. But soon after this the ferment will enter its most active stage, and foam will rise in great swaths, so that it looks like huge rocks tumbling over each other. This is known as iwa-awa (rock foam).

This continues into the highest stage of foam, known as taka-awa, with the bubbles themselves at this stage being very small and fine. This usually occurs about the tenth day or so, but there is great variation depending on a plethora of factors.

The foam rises so high that brewers usually rig a simple rig consisting of a piece of wire that gently spins on a motor with the sole purpose of gradually beating down the foam as it rises. This spares them the need for extremely high-walled tanks. It also aids in sanitation, as one of the greatest sources of sake-spoiling bacteria is foam that has dried on the inside of the tank.

As the fermentation begins to wane, the foam too falls back, leading to the stage known as ochi-awa (falling foam). This segues into a stage with very large, soapy-looking bubbles known as tama-awa (ball foam).

After this foam, too, fades away, the surface of the moromi is referred to as ji, or ground. This stage has many sub-conditions with their own names. Small wrinkles in the surface are referred to as chiri-men (a type of rough cloth). A totally smooth surface is known as bozu, in reference to the shaved head of a priest. If rice solids that did not ferment have risen to the surface, it may look like a lid is on the moromi, and this is referred to as futa (lid).

Much can be told about the quality of the sake at this stage from observing this surface. For example, if the lid is thick, it indicates that a significant amount of wild yeast ended up in the moromi and survived.

This is because the fibers in rice tend to attach themselves to many types of wild yeast, and rice to the surface when pulled by the carbon dioxide molecules, giving that thick-lidded appearance. Brewers know, then, that a thick-lidded moromi in its final stages will often lead to a sake that is rough, acidic and less refined.

Naturally, today these observations are combined with chemical measurements such as acidity, residual sugar, and temperature to create the precise and wonderful flavor profile for they aim. But back in the day, the appearance of the foam was an important tool for brewers in assessing just when a sake was ready.

…and live to tell about it

Some things are not what they seem. That kind of defines sake brewing, and much about the sake world in general. One poignant example of that is judging in sake tastings, as many people imagine that it is a ton of fun. “How cool! Tasting sake for a living! What a great job!”

In truth, there are, in fact, worse jobs. So, it does not totally suck. And I only do it several times a year, so it is hardly a “job.” But really, it is anything but fun.

Of course the first few dozen are cool, fun, and enjoyable. But very few tastings in the sake world consist of only a few dozen sake. More often than not, especially at proper government or industry tastings in which proper and strict scoring is called for, there are about ten times that many. And the judges of course have a responsibility to assess each one carefully, properly and to the best of their ability.

There are many ways of competitively tasting alcoholic beverages. Most tasting competitions have panels that are groups of half a dozen tasters with an experienced leader. If there is less than a clear majority or consensus on any one sample , discussion ensues to round that out up, and that process takes time. Scores are often on a 100-point scale, even if the lower 70 percent of that is never used.

Tasting sake in Japan has always been done a bit differently. Judges work alone, at their own pace, with no discussion with other judges. Scoring is typically 1 to 5, with 1 usually being the best. Judges can work at their own pace, but have to get through all the sake. It gets monotonous: taste, spit, score, move on. Again. Again. Again.

But, really, this is just one more way of doing it. Although it certainly does not need to be this way, it does allow lots of tasters to work through a large number or sake. In fact, one can easily judge several hundred sake in a day in tastings in Japan. Over 25 years of participating in tastings like this, I would say that the typical maximum is 220 or thereabouts.

However, I have done up to 550 in one day. Five. Hundred. And fifty. It was in a tasting held by a distributor in Tokyo, and I participate every year (although the event was cancelled this year for obvious reasons.)

How does one taste 550 sake in one day? One at a time; that’s how.

Obviously, the fun factor wears off pretty quickly. But the hardest part about it is maintaining focus and concentration. Sure, palate fatigue comes into play as well, but more than that it’s mental. And, while of course each sake is assiduously expectorated, after 100 or so the inevitable buzz that you actually do not want rears its ugly head. It’s definitely a long-ass day. What can you do to make it easier on yourself? Several things, in fact.

Breakfast is key. To taste like that on an empty sake is just plain stupid. Still, a huge meal before tasting would dullen your senses, but if too little is eaten the buzz wins, the taster loses. Next, consciously minimize what you take in, and be sure it is consistent in volume. There is no need to take in any more than is necessary to thoroughly assess the sake, and because it is absorbed through the tongue, minimizing that helps.

Obviously frequent breaks for deep breaths and water are essential both mentally and physically. You have to remain focused through the inescapable fog. Also, after a while, a thertain numbneth theth into the tongue. Water, vigorously swished, will usually clear that out.

In one tasting in which I judged years ago for Fukushima Prefecture, they had a unique way of keeping the judges’ palates fresh. On a table in front of a chalkboard, laid out neatly, were a pitcher of water and requisite glasses, two dishes of white powder, and (get this) a bowl of eggs. It didn’t take a genius to figure out this was the palate cleansing station.

The powders proved to be salt and baking soda, and were quite effective in helping my tongue forget temporarily the barrage of ambrosia to which it had just been exposed. The eggs, however, were new to me, and I had to ask how to use them. The egg is cracked, the yolk is manually separated from the white, swished around the palate and swallowed – raw. Of all the options available, this was (surprisingly) the most effective in absolving the taste buds of any previous experience.

The above will help, but nevertheless tasting that much always takes its toll. Don’t plan anything later in the day. While this seems obvious, some people are ambitious – often judges will go grab a beer after tasting that much.

So, yeah, write off the rest of the day, and the first half of the next one as well.

In truth, tastings of that scale are rare. This example is extreme; most people judging will never have to taste that much. Should you ever find yourself a judge in a sake tasting, the above should help you maintain perspective and focus.

This article originally appeared in the April 15 issue of Sake Industry News. 

Amongst the many steps of the sake brewing process, some are more glamorous than others, and that therefore garner more attention. “Koji-making” and “yeast starter” sound so much more romantic than “milling the rice.” As such it becomes easy to dismissively abridge the more mundane-sounding processes, and even more so when modern machines do a much better job than hassle-laden traditional hand-crafted methods.

And rice milling is the epitome of this. We usually say, “first, they mill the rice…” and move on to the more glamorous steps. But that belies how incredibly important milling is. One could say it is the most important step, since if the rice is not milled well – if there are lots of cracked or broken grains as one example – then the rest of the processes will not proceed well and the resulting sake will suffer.

Why, again, do they mill the rice? The objective is to remove fat and protein from the outside of the rice grains while leaving the starch in the middle intact, and doing this in such a way that the rice grains do not crack or break. Protein and fat can give character to sake, but they are usually viewed as the cause of rougher flavors. And avoiding cracking and breaking while milling is important so as to let the microorganisms used in the process to do what they need to do effectively and predictably.

From eons ago, rice in Japan has been milled a bit before being consumed. But really, only the outer eight to ten percent is milled away; that is enough to significantly improve the way it tastes. Long ago rice was milled using using grinding stones, often driven by water wheels when available. But this was rough, and only the very outer portion (that eight to ten percent) could be milled away.

In 1896, the company Satake, located in Hiroshima, developed automatic milling machines that made all that much easier. And that company grew into the largest rice milling machine company in the world, which they remain today. In the 1930s, Satake went on to develop special milling machines to mill rice especially for sake brewing. These employed harder milling stones that were much larger, and through these developments brewers were able to mill the rice much farther then ever before. This technology led to higher and higher milling rates, and eventually, the advent of ginjo-shu.

So for a long while, it was all about Satake. But note, the company’s bread and butter (or rice and pickles, as it were) was machines for table rice, a market they dominate today as well. But there are other milling machine producers, and many have come and gone. Today, the other main company that makes rice milling machines is Shin-Nakano. Both are great companies, and both continue to make their presence felt.

Shin-Nakano, while a much smaller producer of milling machines, is part of larger holding company that owns other sake industry businesses, including a couple of sake breweries as well. And they have maintained plenty of relevance by focusing on craft breweries, and offering plenty of added value, in the form of research with backed by proper scientific methods that has from time to time gone against what has been common sense in the industry. For this and other reasons, many sake brewers stick with Shin-Nakano machines, and they are quite visible in the sake world.

But beyond the machines themselves and their producers, there are developments that start out as ideas in the minds of brewers and such, and eventually work their way into the technology. One of those is what is called Henpei Seimai, or flat milling.

In order to grasp Henpei Seimai, remember that rice grains are not round, but are oblong, kind of like a rugby ball, and the starch center known as a shinpaku within is also basically of that shape. And like many of us human beings, there is much more meat around the midsection than at the top or bottom. This “meat” in sake rice is fat and protein. But when milling machines mill, they take the rugby-ball-shape and make it round by milling evenly everywhere around the grain. This means that, when milling is done, there is more fat and protein around the sides of the shinpaku then at the ends.

If they could somehow maintain the oblong shape and mill more around the midsection then at the top or bottom, a higher ratio of fat and protein could be removed. This idea was proposed about thirty years ago by Mr. Tomio Saito, a former Chief Official Appraiser at the Tokyo Regional Taxation Bureau.

And it worked! The concept was embraced by Daischichi brewery in Fukushima, and others followed soon after that, and Henpei Seimai was born. (Actually, Daishichi takes it a bit further and calls it Cho-henpei Seimai, or “Super Flat Milling.” You can learn more about that here.)

Henpei Seimai does not call for special milling machines. It just calls for modifying and jury-rigging older machines, a lot of skill and a ton of patience on the part of the miller. But basically things are tweaked so that the rice grains fall in fewer numbers against the milling stone, and maintain a vertical orientation as they do. This means that more gets nicked off the sides each time than the top or bottom, and the henpei seimai goal is achieved. So anyone with the requisite skill and experience can do it, it just takes longer, and uses more energy as well.

This is obviously appealing to most brewers: remove a higher percentage of fat and protein with less milling. But since it is a hassle, most brewers do not do it. Yet, amongst those that do, Shin Nakano seems to be the machine of choice, (although that is based on observation and word on the street rather than hard statistics).

However: Satake came back into the mix by recently developing a new milling machine that can do Henpei Seimai, but without all the little adjustments that are normally called for. No mess, no stress. Just select “henpei” and it works. It does it faster as well, and uses less energy in doing so.

But they also took it a step further: Satake developed a slightly different milling outcome that they call Genkei Seimai. Genkei means “original shape,” and as can be surmised from the name, it purports to mill the rice in such a way that it ends up closer to the original shape than normal round milling or Henpei Seimai. The result is that there is more fat around the middle than Henpei, but less than regular milling. However, there is less cracking and breaking since the original natural shape remains more integrated.

They have, in fact, just introduced this machine and this way of milling, so there are not enough results in the field to develop an opinion. That will come, and we will look at some preliminary mumblings in a moment. But to me, the most significant thing about all this is that the mighty Satake is actively getting involved in the sake rice milling game again. That bodes quite well for the sake world.

Back to the differences between the milling methods, please refer to the drawing. Regular milling takes a rugby ball and mills it into the shape of a baseball, Henpei Seimai mills more from the fat-laden sides than the ends, and Genkei Seimai is less flat, and mills somewhere in the middle, with the objective being maintaining the original dimensions, so to speak, of the rice grain.

Several breweries in Hiroshima cooperated with Satake to brew sake that were identical in every way other than one being milled using Henpei Seimai and the other using the newfangled Genkei Seimai. One of them was Imada Shuzo, brewers of Fukucho. The owner/toji, Ms. Miho Imada, sent me a bottle of each to do the comparison.

In truth, I only had one bottle of each, and both were freshly pressed and nama. While certainly delicious, I might be able to tell a bit more with some time in the bottle and pasteurization, but that chance will come in time. And from what I tasted, the results were as subtle as might be expected considering how slight the differences in milling are.

The Genkei Seimai sake seemed sharper and brighter in aromas, but more settled, broader and rounder in flavor. The Henpei Seimai seemed richer in aromas but lighter in flavor. While I am not sure why the aromas were that way, knowing that Henpei was brewed with rice with a bit less fat and protein, the slightly slimmer flavor seemed appropriate. But again, we would need another hundred samples or so to come up with a truly dependable result.

After having brewed with all three types of milled rice, regular, Henpei and Genkei, Ms. Imada emphasized one thing quite emphatically.

“None of these methods is unequivocally better than the other. None will replace the other two; they all have their place. It depends on what kind of sake you want to brew; that’s the deciding factor.”

And, as mentioned above, to me what is most important is that these developments continue to take place, and that important companies like Satake continue be involved at the research and product development levels.

Of course they do…

I do not get to Ishikawa Prefecture often enough. It sits nestled basking in its historical glory, on the Japan Sea side of the country, its rich history former reputation for wealth and opulence in stark contrast to mellowness and sleepiness that pervades much of the prefecture today.

During my most recent excursion there, I was able to visit a brewer called Kuze Shuzo, whose main brands of sake are called Choseimai (“The dance of long life”) and Notoji (“The road to Noto”). As is the case with a lot of Ishikawa food and drink, it’s enjoyable but hard to find near me, enough to cause one to think, “Why haven’t I heard of these guys more often, and why can’t I find this near me?”

They are unique and extremely interesting in many ways, one being that they grow their own rice that is also called Choseimai, although written deliberately with different characters. And one of the most interesting aspects of their brewing practice is the fact that they use two sources of water, one hard, and one soft.

Readers will likely recall a number of things about water used in sake brewing in Japan, including that since in the end sake is about eighty percent water, it exerts massive leverage on the nature of the final sake. And while iron and manganese need to be at very low levels to even begin to think about using a water source for making sake, beyond that brewers discuss the hardness or softness of water. This is measured by the amount of magnesium and calcium or calcium carbonate.

While one is not unequivocally better than the other, hard water encourages a fast fermentation that often leads to full sake with a quick finish, and soft water allows a slower, more lackadaisical fermentation that, when combined with lower temperatures, is conducive to ginjo production and more readily results in sake that is softer, rounder, and more absorbing.

Overall, Japan tends to have slightly soft water compared to the rest of the world. So even what is called hard water here in Japan is actually kind of soft when compared to the water in other countries.

Back to Kuze. They have a well inside the kura as do many producers, and like most places this is of course the main source of water that they use for making their sake. But just outside the brewery is another source of water, a spring that is sourced from a completely different origin, and has a significantly different mineral profile. It is, in fact, fairly hard water.

And so just for the fun of it, or perhaps just be-Kuze they can, they use that hard water for some of their sake. Interestingly, some of their products use both sources of water, i.e. both hard water and soft water in the same tanks of sake.

This of course complicates things hugely, and is in essence a nod to the history and culture of their immediate environs. And good marketing of course, if you can get people to listen to the story.

As they explained their brewing philosophy and methods to us, they eventually came to the sake that is brewed with both sources of water. And it came to light that they limit the hard water to being used in the moto, i.e. the yeast starter, and the soft water to use in the moromi, i.e. the subsequent fermenting mash.

Bear in mind that when making sake, the first milestone is the moto – the yeast starter – which takes two to four weeks to prepare, and the goal of the moto is to have a mini-batch with an extremely high populations of healthy, strong yeast. After that, more ingredients are added in three stages, roughly doubling the size of the batch with each addition, and then fermented for an additional three to five weeks, with the goal this time being more alcohol, and enjoyable flavors and aromas of course. This longer fermentation is often carried out at lower temperatures, and much more slowly, as such conditions encourage cleaner and more aromatic sake.

So when they told us that they use the hard water for the yeast starter stage, and the soft water for the subsequent longer fermentation, I immediately thought, “ of course they do.”

Indeed, of course they do it that way. While it does in fact make total sense, it is quite instructive to note why.

Remember that at the moto stage their goal is creating a strong yeast starter, and that means they want the moto to ferment strongly, so as to have the yeast reproduce quickly and healthily. And hard water will support that. Conversely, they want the subsequent moromi stage to take place more slowly, to some degree inhibiting fermentation speed, to bring out more appealing aspects of flavor and aroma in the final sake. And softer water will encourage that.

So, yeah; of course they use the hard water for the moto and the soft water for the moromi.

With about 1200 sake breweries out there today, and almost all of them making decent stuff, it is hard to do something truly unique yet still somewhat orthodox – and still be tasty enough to sell well. While it is not a choice that is open to many breweries, Kuze Shuzo has found one way to do just that. And when you hear of just how they do it, there is naught to say but “ of course they do!”

The epitome of it all expressed at Kikuyoi

As the climax of the Sake Professional Course Level II course, we visit a couple of breweries. This year, as is the case most years, we head down to Shizuoka Prefecture a couple hours south, wherein sits majestic Mt. Fuji and about 30 great sake breweries. One of them makes a sake called Kikuyoi.

The two largest sake brewing regions in Japan are also the most accessible!

When work, vacation or other travel brings you to Japan, if you are reading this newsletter, chances are you will be interested in checking out something sake related. If you are here during the brewing season in the winter, many if not most sakagura (breweries) are open to tours, although in almost all cases you would need to call ahead and make reservations and arrangements. So if you or someone you are with speaks the language, this should be no problem.

If you do not have the linguistic wherewithal, though, all is not lost. In Kobe and Kyoto there are several museums attached to sake breweries that have plenty of information in English, and have normal business hours that provide flexibility in allowing guests to drop in almost any time with no reservations.

While museums might not seem like the most sake-intensive experience you can have, these are actually quite informative, interesting and fun. So here is a quick rundown of accessible places to visit in Kobe and Kyoto.

The Nada Region of Kobe

The Hakutsuru Sake Brewery Museum

This museum is constructed in one of the old brewery buildings. You need to check in at the main gate. But once that trauma is over, you wander into a beautifully preserved building with a gorgeous garden at the entrance, with the ultra-modern sake brewing plant all around you. Be sure to get an explanatory brochure upon entering (available in several languages). Then, explore the self-guided tour on the first and second floor. There are, at each of perhaps eight stations, television monitors with wonderful two-minute videos showing the major steps in the brewing process, complete with old film footage. Narration is available in either Japanese or English – just select the right button. There are also extremely detailed scenes with manikins and well-preserved traditional old brewing tools that convey quite a realistic feeling of the work load of old. When you are finished, there is a small sake sample of which to partake, along with a video of how to properly taste sake.

Also, the gift shop is great, with both great sake and wonderful accoutrements on sale. All in all an excellently informative tour. If you have time for only one place, this would be it.

4-5-5 Sumiyoshi Minami-machi
Higashi Nada-ku, Kobe
TEL: 078-822-8907.
Open daily 9:30 – 4:30, closed Mondays.
Access: Five-minute walk from Hanshin Sumiyoshi Station. Fifteen-minute walk from JR Sumiyoshi Station.
Admission free.

The Kiku Masamune Sake Brewery Museum
Perhaps a ten-minute walk away, this museum was destroyed in the Great Hanshin Earthquake that devastated Kobe in 1997, and reopened in January of 1999. The gate and entrance way have been well restored to their original rustic beauty. Be sure to grab one of the lovely brochures (in English or Japanese) at the entrance when you sign in, and look for a detailed map of the breweries in Nada if you do not already have one. In the first large room is an excellent video from 1934 showing black and white brewing scenes, to vintage music. The narration is all in Japanese, but the scenery is easy enough to understand, and the accompanying music is classic. Excellent coverage of large-scale brewing back then, with dozens of men at one time mixing moto (yeast starters) or stirring vats. A small model of a Tarukaisen, the ships that went back and forth between Kobe and Edo, doing nothing but delivering casks of sake, sits near the entrance. Here there are less large brewing implements (although there are some), and more small storage vessels, like bottles and tokkuri and red, lacquered “tsuno-daru.” When you are finished, there are several sake to be sampled in the tasting and retail purchase room.

1-9-1 Uozaki Nishimachi,
Higashi Nada-ku, Kobe
TEL: 078-854-1029.
Open daily 10:00 – 4:00, closed Tuesdays.
Access: Five-minute walk from Hanshin Uozaki Station.Two-minute walk from Rokko Liner Minami Uozaki Station.
Admission free.

Sawa no Tsuru Sake Museum
A short taxi ride away is Sawa no Tsuru’s wonderfully charming museum. Originally constructed in 1978, it was totally destroyed in the Great Hanshin Earthquake. It was reconstructed as a replica of the original, and opened in March 1999. Here, you start with a short film as well, half modern reenactments and half cartoons. But it gets the point across visually. You then follow the flow of the original brewing steps in the old kura. Of particular interest are the reconstruction of the kama (rice steamer) area, and the sunken funaba (sake pressing box) area. Dozens of wooden brewing vats, lined up as they might have been long ago, convey a feeling of what it must have been like. A model of a Tarukaisen is on the second floor. Each of these ships could carry about 1000 koku, or 180 kiloliters, in small casks. That is equivalent to the yearly production of many kura today. When finished, there is a tasting room which offers only one sake for tasting, their genshu honjoz-o, but there are plenty of interesting things like pickles and snacks to purchase.

1-29-1 Oishi Minami-machi
Nada-ku, Kobe
TEL: 078-882-6777
Open daily, 10:00 – 4:00, closed Wednesdays.
Access: Fifteen-minute walk from Hanshin Oishi Station.
Admission free.

Kobe Shushinkan

And then there is Fukuju…

The Kobe Shushinkan brewery was damaged severely in the Great Hanshin Earthquake in 1997, but has done a great job of rising from the ashes. The international award-winning sake brewed by this company is called Fukuju, and it is fairly prominent and lively especially compared to other sake from Nada. Tours are available, but not on a walk-in basis. You can learn a lot more about their brewery and facilities here and you can very easily make a reservation via email here to tour the brewery. It is very worth taking the time and planning ahead, and reaching out to set up a tour.

Also, they have an extremely cool shop, with sake, sake-related vessels and really interesting trinkets (like coin purses made from old sake filtration bags), and sake-friendly nibbles. Finally, the restaurant Sakabayashi is top notch, although reservations are necessary here too.

Lastly, if you click on the “Sake Breweries” link at the top of the first link mentioned above, you can see a list of all the breweries in Nada that offer tours, as well as a cool sake-centric map of the area.

Kobe Shushinkan
1-8-17 Mikage-tsukamachi, Higashinada-ku, Kobe, Hyogo 658-0044

TEL 078-841-1121
Open Daily 10-6

There are several other museums and points of interest in Nada, both museums and restaurants. A very useful map, entitled “Sake Breweries of Nada” and shown at left, can be found here. In fact, a proper search will reveal a whole bunch of maps of Nada sake breweries. And, in fact, a plethora of Nada maps can be found here, the result of a simple search.

Fushimi Region of Kyoto

Gekkeikan Okura Memorial Hall

In Fushimi, there are almost 40 sakagura, many in one tight neighborhood worth a walk-through. But perhaps the best museum would be Gekkeikan’s Okura Memorial Hall sake museum. Arguably the most significant brewer across the history of the sake world, many of Gekkeikan’s industry firsts are on display here. There is a partially viewable mini-kura attached, and a restaurant just around the corner. It is in the opposite direction from JR Kyoto station as most of the traditional Kyoto sights, but by no means out of the way. If you go to Kyoto, at least get here.

Also, right around the corner from this is a sake café that where you can try three sake from each of the breweries in Fushimi. Called the Fushimi Yume Hyakushu, it was the original head office of the company making Gekkeikan.

Gekkeikan Okura Sake Museum (Okura Memorial Hall)
A five minute walk from Chushojima station (Keihan line).
Phone No. 075-623-2056 Admission fee 300 yen (but you get a sake gift upon leaving!)
Open 9:00 – 16:30 Closed Mondays

Kizakura Kappa Country

Kizakura, also in the top five or six sake breweries in the country in terms of production, has amped up their tourist facilities with their Kizakura Kappa Country, with a restaurant, tasting room, and more – of both beer and sake.

It is a new-ish facility but it is in fact their original brewery building. You can see the brewing process here in all its largess, as well as lots of other sake-related stuff. Kizakura has always been a prolific advertiser, unlike most sake breweries, and you can see many of the advertisements they have used over the decades going back into the 50s.

And you can of course try (and buy!) their sake here. Furthermore, they also make good craft beer, and this too is available for sampling and sales at Kappa Country. The sake and beer are both more enjoyable with food, and of course there is a restaurant here as well so that you can confirm that for yourself.

By the way, a kappa is a mythical creature of dubious nature that has long been the corporate symbol for Kizakura. Learn more about kappa here.

Kizakura Kappa Country
228 Shioya-machi, Fushimi-ku, Kyoto City
Tel: 075-611-9919
Opening hours: 10am to 5pm
Closed on Mondays (unless Monday is a national holiday)

There are a few more breweries worth knowing about, and a few more sites to check out in Fushimi, and you can learn a bit about here. Of particular note is the place called Fushim Sakagura Koji, which is a indoor labyrinth of perhaps 20 restaurants and sake bars, at one of which you can order a flifght of 17 (count ‘em!) sake from Fushimi. Also of note is the sake retail shop Aburacho, which sells tons of Fushima sake, and where you can taste almost any sake from Fushimi brewers in the bar in the back. See more on that at the bottom of this guide page.

A guide to the sakagura of Fushimi can be found here, within which is a good map of those sakagura, and a veritable plethora of Fushimi maps can be found here.

If you are visiting Japan, even without a fully congealed plan, you simply must avail yourself of visiting at least the most accessible sake related places. Hopefully this guide will get you started. But remember, in many regions around Japan there are breweries open to visits – so be sure to check that out whenever you find yourself in places less accessible than Tokyo, Kobe and Kyoto.
