Jika-gumi: Directly to Bottle?

Really?

tobiniriIn last month’s newsletter, we spoke of the middle part of the pressing, and its numerous names. In other words, when the rice solids that remain after fermentation are filtered away, via a press of one sort of another, the terms nakagumi, nakadare and nakadori all mean the same thing, and all refer to the middle part, which is what comes out after the rough first part but before the start of the tired final bits. In other words, the middle part is the best.

And there is no end to the list of vaguely defined and less than universally applied terminology in the sake world. It keeps things delicately balanced on that fine line of interesting and frustrating.

Another variation of sake worth knowing about is something called jikagumi, which can be loosely but understandably translated as “directly from the press.” As might be clear from that English rendering, jikagumi on a label means that the sake was bottled directly from the pressing apparatus.

While that pressing apparatus may have been a modern machine (good), a traditional fune box press (better) or just drip-pressed (best), the sake in yabutathat bottle went directly there. This differs from the norm in that most sake is first sent to a big tank where it all sits for a spell. Further sediment will settle, and the sake in that one tank is all thereby guaranteed to be uniform in taste and aroma.

Furthermore, almost all kura will then blend the tanks of a given product brewed in that year to make sure that each bottle tastes the same. But jikagumi will render each bottle just a little bit different, at least in theory, since (supposedly) it was not blended with any other bottle.

So, not only is jikagumi sake not blended with others, it also should be muroka (unfiltered, or at least, no charcoal or ceramic filtering), genshu (undiluted) and nama (unpasteurized). However, sake can be pasteurized in-bottle as well, so jikagumi can in fact be pasteurized by the time we get it.

funeThrow all that together and in a sake labelled jikagumi, we can count on having an unfiltered, undiluted sake that has not been blended with any other bottle or batch. This makes it appealing in that each bottle is unique in our time-space continuum, in our universe, and in our reality. Wow.

There are just a couple of problems with this: one, they are not allowed to legally do that, and two, practically speaking it is not very realistic.

However, as the term is not legally defined, there is some leeway in the interpretation, and at the end of the day the point is to give us something close to the above. Which is nice.

Legally, when a brewer makes a sake, they press it (filter out the rice solids), and then they must send the sake to one tank, and weigh it. Concurrently they weigh the kasu (lees), or the rice solids remaining from the pressing process. The weight of the sake and the weight of the kasu are recorded – and their sum must equal the weight of the moromi (fermenting mash). Once this has been done and officially recorded, the brewer can bottle the sake, but not before. The point is, of course, to make sure that no sake slips through the tax-cracks.

So from that point of view, jikagumi is not legal. However, thanks to the vagueness of things in Japan, some tax authorities may allow a brewer to bottle it directly, and count the number of bottles multiplied by the volume of each. It should be the same thing, right? Indeed. And surely that is how some places are handling it. Prolly.

Also, practically speaking, it is very labor intensive and a huge hassle to hold one bottle after another under a funnel gathering sake dripping from the fune1press. We are talking like 2500 bottles for an average sized tank of premium sake, one after another. One. After. Another. Sure, the whole batch need not be done that way, and only a few bottles could be labelled as such. But still: it’s “hassle city.”

And in fact, when sake is pressed, it is first allowed to gather in a small holding tank called a kame, and as the kame is filled it is repeatedly pumped to a larger tank. So in truth, something called jikagumi would not even be allowed to gather in the kame. To not do this would call for changes and tweaks that would drastically affect the flow of things.

Yes, it can be done. But it has legal and practical limitations. But yes, it is being done, at least based on the fact that sake labelled jikagumi are out there.

However – and this is important – the term is not legally regulated. So in truth a brewery does not have to it by any set of rules at all. Just because funneljikagumi is written on the label does not legally mean that anything had to happen or not happen. Trust that no one is trying to fool us here, but rather that some leeway of execution exists.

But knowing what jikagumi is (sake bottled directly from the press), and also knowing what it should not be (legally or practically doable), we are left with what the term actually implies.

And that is this: a unique sake to which as little as possible has been done between brewing and bottling. Therein lies its goodness, and its appeal.
In truth, sticking to strict definitions will not serve us here. (They rarely do in the sake world, but I digress.) The spirit of things is what is important.

There was, a few years ago, a spate of jikagumi sake. I recall seeing lots of them during seasonal tastings, usually from smaller brewers with a willingness to experiment and create more appealing sake. But then, I noted that less and less of them were visible.

Upon inquiry, it was as I expected, and as readers might infer from the above. In other words, because the term was not likely to be exactly as it was suggesting, and because there were potential legalities involved, some of the brewers using the term began to steer clear of it, opting for instead other appealing marketing terms. So as quickly as it appeared, it is fading from lexicons a bit. Yes, there are jikagumi sake out there, and yes, they are potentially special and wonderful. But they will not likely constitute a trend with any momentum.

So a sake with jikagumi on the label might not really be so; but it will be as close to that as was legally and practically possible. Enjoy it for what it is.

Sakagura: How Big is Big? How Small is Small?

In any industry there are big players and little players. There are always huge companies that produce DSC02231widgets – or sake – in volume, with stable quality and cost-efficiency. And there are also companies that produce much less and do everything on a smaller scale. This juxtaposition exists in the worlds of widgets, beer, wine and of course sake.

It is important to acknowledge that both scales of operation are good. They are all good companies, the big and the small. Or at least, if they are not good companies, it is not a function of their size. So it is important not to lean one way or the other, not to prejudice against either the big or the small, and to appreciate what both big and tiny sake companies contribute to the overall picture.

There is much to say about this situation, and I go out of my way to support brewers of all scales of operation. But let us save that long and interesting conversation for yet another day.

What is quite interesting to grasp, though, is just how big is big, and just how small is small? And how do the twain compare? The figures can be eye-opening.

CIMG3925To begin with, the sake industry is very polarized. There are just about 1200 kura (breweries) actively making sake these days. Or at least, 1200 that say they are making it. The truth might be more like 1000, but I digress. Let this be a part of the conversation we have set for yet another day.

Of those 1200, about only 15 combine to account for over half the sake made on the planet. Fifteen. Make. Half. And at the other end of the polarized spectrum, we have about 1000 breweries that combine – all one thousand of them – combine to comprise 25 percent of the market. Numerically expressed 0.8 percent of the kura pay 52 percent of the sake taxes. Conversely, 94% of the industry combines for 25 percent of the sake taxes. Dotted across the chasm between these two there are 200 or so kura of medium and stable size.

Look at those number again. Think about them. It’s a huge spread.

What is interesting is that the large companies have their own challenges and responsibilities as an CIMG1932enterprise, and problems-opportunities that only large companies can have. And the smaller companies, which often make barely enough to be sustainable and barely profitable, have their own sets of trials and tribulations to face – as well as challenges and opportunities. Neither one is inherently better than the other.

The difference in the size of the big and the small is astounding. For example, if one tours Hakutsuru in Nada, the biggest company in the industry, there is a raised hallway from which we can look down on four identical pressing machines that are more or less continuously cranking out just-completed sake.

There is a sign on the wall that runs through some rudimentary math, and tells us that if we were to drink two full glasses of sake a day, every day (hey, no problem here!) it would still take 220 years to finish what was pressed in the room below in a single day. And bear in mind this is but one of their several facilities (albeit the largest for sure).

Hovering clustered near the other end of the scale are about a thousand breweries that make in an entire brewing season about half of what the above-mentioned place makes in a single day. It’s whacked to say the least.

CIMG1947During the Japan-based winter running of the Sake Professional Course each year, I take the group of attendees to four kura. One is impossibly tiny, the brewers of Soku in Kyoto. They have five tanks, each of which will yield about 2000 bottles of sake at a pop. He will rotate through them and end up using each two to three times. He employs like five people, including his wife and his mom.

The next day we visit the largest brewer in the industry, the aforementioned Hakutsuru. In one of the two brewing buildings we visit, there are about sixty tanks, each of which can yield about 20,000 bottles – ten times the other place. They make four a day of these, and press four a day. That alone is 40 times the production of the other – from but one of their kura. And it’s delicious honjozo as well!

Each has different means, ends, and philosophies as well as different resources, infrastructures and goals. And I emphasize again: they are both great companies, and both companies make some great sake.

Many of us love to love the smaller kura because of their romantic appeal, and surely it is there. I’ll not CIMG1948deny that. We all love a good story, wherein a small kura has the flexibility to try new rice or yeast types, to make sake of which there is little and it’s hard to get, where little old ladies put on the labels by hand and where they can’t even spell the word machine, much less use any. Sure; that’s fun.

But there are just as many interesting, impressive and satisfying stories about the large brewers, and their sake can be great and always well priced. Bear in mind, companies like that can make exactly what they want, and with great consistency. And their contributions to the industry over the years have been indispensable to its progress.

So in the end, don’t let size be a factor. But at least be impressed with the difference in scales of operation in this highly skewed and polarized traditional industry

End-of-season Festivities: Koshiki-daoshi and Kaizou

The sake brewing season is drawing to a close. Except for the handful of large breweries that brew year-round in climate controlled factories, most kura will be finishing up their brewing sometime this month. Naturally, there will be ceremonies tied in to significant activities within the kura. One such activity and ceremony is known as koshiki taoshi.

The large vat used to steam the rice in sake brewing is called a koshiki. In traditional breweries, the koshiki is made of wood (cryptomeria, or Japanese Cedar) and sits on top of a large iron pot of water called a kama that tapers a bit at the top. (If you have ever had kama-meshi, rice, vegetables and meat steamed in a small iron single-serving pot, the kama for this is  very similar in shape.) Beneath the floor, this kama is heated (long ago by coal, wood or oil) to produce the steam for steaming the rice.When the final batch of rice for the season has been steamed – usually sometime in April – the koshiki is removed from on top of the kama and knocked over (taoshi) on to its side for a thorough cleaning. This is what “koshiki taoshi” refers to: knocking over the rice-steaing vat. In other words, the last of the year’s rice has finally been steamed.

But more takes place than simply knocking over the vat. It symbolizes the beginning of theA yeast starter in action end of a long season of brewing, and as such a party is in order. A big announcement is made. The kuramoto (brewery owner) and all of the kurabito (brewery workers) have a celebratory meal. Also, a bit of newly-made sake is offered to the gods in thanks for the blessings of the brewing season.

Note that just because the last batch of rice has been steamed does not mean there is no work left to be done. There are still several tanks fermenting away, and it can be as much as another month before these will be finished and pressed. Completely finishing the final batch of the year is referred to as kaizou. And after kaizou, there is naught to do but clean up and go home for the summer. But the koshiki-taoshi is indeed a light at the end of the tunnel.

Today, things have changed a bit. Rare is the wooden koshiki sitting upon the coal-fired kama. Infinitely more common is a stainless steel koshiki with steam pumped in by hoses from a natural gas fired boiler. Often these are equipped in such a way that they can be turned sideways to make it easier to scoop out the rice. Kinda makes knocking them over a bit anticlimactic.

Large brewers sometimes have “renzoku jomaiki” (continuous rice steamers), huge Fermenting awaycontraptions that steam rice and pump it out onto a conveyor belt on a continuous basis. Some even use rice liquefying machines in place of steamers. Some concessions to modern times must be made, even in this feudally traditional industry. But nonetheless, the significance of steaming the last of the season’s rice is huge, and a ceremony and small party are held to acknowledge the significance of the last steaming of the season.

Also, the breweries that brew year round often shut down in July or so for yearly thorough equipment maintenance. This is the time when such breweries will celebrate their koshiki-taoshi.

After a cold winter of long days of grueling labor, a glimmer of the quiet half of the year to come must certainly be welcomed.

Brewing Beginnings of Autumn

It all begins again…

Fall has fully entrenched itself, complete with its colors, cooler weather, and culinary delights. It is also the most significant time of the year for the sake world: the brewing season is about to begin.

fallleavesExcept for a few dozen brewing factories operated by the largest sake brewing companies, sake is brewed in the colder months, generally from the end of October to the beginning of April, give or take a few weeks each way. Sake fermentation takes place at lower temperatures, and as such cannot be sustained during other times of the year. Larger brewers have facilities that keep fermenting tanks cold all year round, and although the quality of sake brewed in such facilities can be just as high, breweries with these facilities constitute the exception and not the rule.

Historically, tor taxation and accounting purposes, the sake-brewing year began October 1st of each year. (Currently, it is actually July 1.) Although this has always been the most practical time to begin, the shogun made it official in 1798 by dictating that no sake brewing was permitted before the Autumn Equinox. Stipends to samurai and taxes were paid in rice, and sake was brewed with what was left. Hey, first things first.

Much has changed over the last several centuries, yet much has remained the same. There are a number of *then and now* comparisons that can be made.

JG_SPC-23One thing that has not changed much is the connection between sake brewing and Japan’s indigenous religion, Shinto. Almost every brewery in the country has a small Shinto shrine on the grounds, and often a larger one nearby the brewery. At the beginning of the brewing season, the brewers, owner and other employees will gather with a priest for a ceremony to pray for a successful and safe brewing season. This takes place at even the largest breweries, amidst gleaming, modern equipment.

Until a scant few years ago, kurabito (brewers) and toji (brewmasters) were almost exclusively farmers from the rice-growing countryside with no work in the winter. They would travel a fair distance from their homes and live in the brewery throughout the six month brewing season. This is an integral part of how the culture of the sake world developed.

image41370_thumbnailTo some degree, this is still the case today. Most brewing personnel are fairly advanced in age, and still make the trek each season to live away from home. But things are indeed rapidly changing. It has become painfully obvious to the industry that young blood is desperately needed. As such, most places now use some local people as brewers, normal folk that go home at night to their families and in a few instances even punch a time clock.

Most kura actually use a bit of a hybrid system, in which the oldest and most experienced brewers and the toji are experienced journeymen from the countryside living in the brewery, but the heirs apparent, the next generation of brewers, are young and local. It is a phase of transition to the future of sake.

Still, many young brewers find it difficult to relate to their older sempai, and quit under the pressure of the harsh, feudalistic treatment of old.

The presence of women in the brewery is another interesting then-and-now comparison. Until quite recently, the presence of women in the brewery was anathema. Bizarre beliefs (or excuses expressed as such) dictated that the mere presence of a female amidst the fermenting tanks would cause all kinds of problems, both technical and psychological.

While many older male brewers still have some resistance to women in the kura today, many breweries have women helping in the day to day brewing tasks. There are even a handful of toji that are women (23 as of last year).

P3090055Young or old, male or female, any day now the brewers will gather at their brewery and begin the arduous task of preparing for the season. The first couple of weeks involve nothing but cleaning. Sanitation is paramount, especially with the open fermentation methods of sake brewing. Everything will be scrubbed, cleaned and sanitized.

Soon after, the milling of rice will begin, followed soon thereafter by the first batches of sake. Brewing begins with lower grades of sake. As the weather becomes progressively colder, higher grades of sake will be brewed, with the ginjo-shu brewing period peaking in January and February.

The inside of today’s sake breweries also contain a mix of ancient and modern. Much of the equipment is modern, things like boilers, fermentation tanks, and even the occasional computer. But much remains as it was long ago.

Most brewery buildings themselves are old, classic studies in Japanese architecture. Many of the brewing tools remain rudimentary. There are plenty of bamboo poles and brushes, and other implements fashioned from traditional materials, as they have yet to be bested by modern counterparts.tobiniriYet, mixed in with these tools of old are modern gadgets, everything from temperature sensors and automatic mixers to full-on koji making machines and conveyor belt driven continuous rice steamers. Each kura draws their own line on how much automation to use.

Regardless, this time of the year holds great significance in the traditional sake-brewing world. And so, as the centuries-old traditional cycle begins again, let’s all hope for another safe and successful season.

Shochu and Awamori

What is Shochu?

Shochu is Japan’s other indigenous alcoholic beverage, but unlike sake, shochu is distilled. It is also made from one of several raw materials. The alcoholic content is usually 25%, although sometimes it can be as high as 42% or more.

The word “sake” in Japan can actually refer to all alcoholic beverages in general, although it most often refers to the wine-like rice brew so tightly associated with that word overseas. But in some parts of Japan, most notably the far western and southern regions, the word sake is understood to refer to a totally different alcoholic beverage, also indigenous to Japan, but distilled and not brewed: shochu.

Like almost all such beverages throughout the world, shochu developed as it did as an expression of region, especially climate, cuisine and available raw materials. Perhaps the factor most affecting the development of shochu is the weather. The island of Kyushu and the western part of the island of Honshu are significantly warmer than the rest of Japan.

Brewing sake calls for relatively lower temperatures, but shochu can be distilled in these warmer regions. Also, the higher alcohol content and drier feel is more appealing to many in milder climates.

Unlike many other beverages, shochu is made from one of several raw materials. These include sweet potato, and shochu made from these is called “imo-jochu.” Other materials commonly used include from rice, soba (buckwheat), and barley. There is even one island where there a few places that make shochu from brown sugar. It can also be made from more obscure things like chestnuts and other grains.

And, each of these raw materials gives a very, very distinct flavor and aroma profile to the final sake. These profiles run the gamut from smooth and light (rice) to peaty, earthy and strong (potato). Indeed, each of these raw materials lends a unique flavor in much the same way that the peat and barley of each region in Scotland determine the character of the final scotch whiskey.

There are, in fact, many parallels between shochu and scotch, regional distinction based on local ingredients being only one of them.

Another parallel to scotch can be found in the distillation methods. There are basically two main methods of distillation. The older method – it has been around since the 14th century or so – involves a single round of distillation only, and is made using only one raw material. Known as Otsu-rui (Type B – in an admittedly loose translation) or Honkaku (“the real thing”) shochu, this type will more often reflect the idiosyncrasies of the original raw material. In this sense, it can be likened to single malt scotches.

The second method is one in which the shochu is goes through several distillations, one right after another. It is often made with several of the commonly used raw materials. Known as Kou-rui (Type A, in the same admittedly loose translation) shochu, this method has only been around since 1911, although it only became a legal classification in 1949. With a bit of a stretch, this kind of shochu is similar to much blended scotch. In other words, it is much smoother, ideal for mixing in cocktails, and with much less … well, character.

Beyond these variables, the type of koji mold (used to create sugar from the starch of the raw materials during the fermentation step that necessarily takes place before distillation) can be one of three, (yellow koji, as is used with sake, white koji and black koji) and the distillation itself can take place at either atmospheric pressure or at a forced lower pressure. These parameters too naturally affect the style of the final product.

Kou-rui shochu, of which much more is produced by far, is quite versatile. As it is lighter and cleaner, it lends itself well to use in mixed drinks. Perhaps its most ubiquitous manifestation is the popular “chu-hi,” a shochu hi-ball made using a plethora of different fruit flavors and sold in single-serving cans or mixed fresh at bars and pubs. (Since it is supposedly cleaner by virtue of having been repeatedly distilled, it is said by some to give less of a hangover, although there is no evidence to truly back this up.)

Otsu-rui shochu, the “real thing” honkaku-shochu, on the other hand, has a more artisan, hand crafted appeal associated with it. The nature of the raw material can really come through, and be it soba, rice, barley, or chestnuts, each has its fans and foes. This is especially true when it has been distilled at atmospheric pressure, not forced lower pressure.

Perhaps the most interesting – and illustrious – of all shochu are those made from the sweet potatoes of Kagoshima Prefecture: imo-jochu. While the flavors can be heavier and more earthy than shochu made from other starches, Kagoshima imo-jochu offers complexity and fullness of flavor that makes it quite enjoyable to many a connoisseur.

Honkaku “the real thing” shochu is usually enjoyed straight, on the rocks, or with a splash of water. Another way to enjoy either type of shochu is known as “oyu-wari,” which is simply mixing it with a bit of hot water. This both backs the alcohol off a bit, releases flavor and aroma, and warms the body to the very core. Unbeatable in winter, for sure. From experience, I can guarantee it will warm you from the core outward.

Shochu overall is enjoying massive popularity these days in Japan. Over the last couple of years, both beer and sake consumption have continued to drop, where as shochu has actually increased.

While shochu has its roots in either China or Korea, probably having come across during trading, the traditional home of shochu in Japan is Kagoshima, on the island of Kyushu. In fact, the first usage of the term shochu appeared in graffiti written by a carpenter dated 1559 in a shrine in the city of Oguchi in Kagoshima.

Kagoshima is rightfully proud of their shochu heritage. It is the only prefecture in Japan that brews absolutely no sake, but only produces shochu. If you ask for sake down there, expect and enjoy the local sweet-potato distillate.

The difference between soju and shochu

Korea also makes shochu, although it is called soju in Korean. And, Korean producers got to the US with it first. As such, in US legalese, the product is known as shochu. As far as I know, all Japanese shochu will be legally referred to as soju in the US. It is, in essence, the same thing. Judge it on its flavor, not its label.

What is Awamori?

Awamori is an alcoholic beverage indigenous to and unique to Okinawa. made from rice, however, it is distilled from rice, not brewed. The traditions and methods of Awamori originally came in from Thailand (although with influences from the south, from Indonesia and Taiwan, and from the north, from China and Korea it is said), and awamori was actually the very first distilled beverage in what is now Japan.

Awamori is made only in Japan’s southern most prefecture, the tropical island group of Okinawa. Currently, there are but 47 makers of this unique, earthy beverage, although awamori is enjoying a boom right now, and business is brisk. Due to the influence of the US presence from WWII until 1972, for decades the drink of choice in Okinawa was scotch or whiskey. Now, however, this erstwhile gift to the Shogun of Japan has resumed its rightful place as a very popular sipping beverage in its own land.

There are quite a few ways in which awamori is unique. The pre-distillation ferment is made in such away that there is plenty of citric acid created, which allows awamori to be made all year round in this hot climat. It is distilled once, and afterwards the alcohol content is lowered with water to about 25 to 30 percent, although some awamori is found at 43 percent alcohol.

There are several theories on the origins of the word awamori itself. “Awa” means foam and “mori” can mean to rise up. One theory then is that the foam would rise in great swaths during per-distillation fermentation. Another is that long ago the level of alcohol was measured by pouring the awamori from a height of an outstretched arm into a small cup, and measuring how much foam rose in the cup. Yet a third, less romantic, states that this name was forced upon the Ryukyu distillers by the Satsuma clan of Kagoshima to be sure that it would not be confused with their beloved shochu.

Etymological considerations aside, as mentioned above, awamori is a beverage distilled from rice. It differs from sake, mainland Japan’s indigenous drink, in that sake is brewed, not distilled. Also, sake is made with short-grain Japonica rice, whereas awamori is made using long-grain indica rice that is imported from Thailand (even today). It differs from shochu, Japan’s other distilled beverage, (although much shochu is made from materials other than rice) in several ways, including process variations, as well as the type of koji mold (used for saccharification) and yeast.

A word worth remembering when shopping for awamori is “kusu.” Kusu is aged awamori. It is written with the same characters as the Japanese word koshu, which refers to aged sake, the pronunciation is unique to Awamori and Okinawa.

Awamori was meant to be aged, and aged for a long time. Like many beverages distilled from grains, aging mellows the flavor and rounds out the edges. While awamori aged ten years can be wonderful, it becomes even more enjoyable at 20 or 25 years. (One of the challenges to the awamori industry is how to remain financially viable while they wait on the returns of their long-term investment.)

But the traditional method of aging awamori, known as “shitsugi,” is very curious and does not boast a high degree of repeatability. To explain it, we need to bear in mind that hundreds of years ago, when the Ryukyu kingdom was in its heyday, folks would have several lidded urns of awamori lined up outside the house. The urn containing the oldest awamori was closest to the door, with each urn having successively younger product inside.

When a drink was ladled out from the first urn, the amount taken was then replaced with awamori from the second urn. This in turn was refilled from the third urn and so on. Freshly distilled stuff was placed into the last urn when ready. This led to each urn having inside of it an indeterminable blend of awamori of different degrees of aging. So although kusu refers to aged awamori, traditionally it was not really possible to be any more precise than that.

Modern times, laws, and consumer guidelines call for a bit more accuracy, and currently for a bottle of awamori to have kusu on the label, at least 51% of the contents must have been aged at least three years. While this allows for the traditional shitsugi method of aging, it still means that 49% of it could be freshly distilled stuff. So, while it may be a bit harder to find and a tad more expensive, it is worth it to search for 100% kusu of ten years or more. It will be clearly written as such on the bottle, i.e. “100% aged 10 years,” or something to that effect. Having said that, it is very difficult to find something like a bottle of kusu of which 100% has been aged 25 years.

When the Ryukyu kingdom was in its prime, the best kusu was served at only the most special of occasions. It was presented in very small thimble-sized cups, called “saka-jiki ,” holding perhaps a tablespoon, that are dwarfed by the average “o-chokko” sake cup. These ae still used today in some situations. It was said that while wealthy people might entrust their money to others, they would always keep the keys to their awamori cellar with them.

The land

Rice paddy sunsetThe region from which a sake comes is indirectly connected to the type of rice, since just like grapes and wine, different rice strains grow better in certain regions. Small as Japan is, there are many distinctly different climates, and different things grow in each.

This page, once developed, will explore some of the key variables related to land and weather.

The koji

Koji is one of the crucial ingredients in sake brewing

Just what is Koji?

Koji baskets

Koji being cultivated in small trays

Koji is steamed rice that has had koji-kin, or koji mold spores, cultivated onto it. (See photo at right, which is a grain of rice cultivated with koji mold.) This magical mold, for which the official scientific name is Aspergillus Oryzae, creates several enzymes as it propagates, and these are what break the starches in rice into sugars that can be fermented by the yeast cells, which then give off carbon dioxide and alcohol. Without koji, there is no sake. For what it is worth, sake is not the only beverage in the world using koji. There are a couple of others throughout Asia. But the brewing methodologies are vastly different.

A quick comparison between the production methods of sake versus other alcoholic beverages may prove useful. Wine is fermented from grapes, which already contain sugar (glucose, to be chemically correct). This is what yeast cells need for food. There are other kinds of sugars, but they cannot be metabolized by yeast. So in winemaking, yeast is added to a liquid already containing sugar.

Beer and other beverages made from malted barley begin not with sugars, but with starches, which are molecularly monstrous. Here, brewers employ enzymes brought out in the barley malting process (where the barley is moistened and warmed, i.e. the sprouting process begun, albeit artificially) to break down the starches into sugars. These enzymes, which activate within very specific temperature ranges, chop the starch chains into much smaller sugar molecules. Some will be glucose and feed the yeast, some will be chemically different sugars and add to flavor.

Koji spore

Grain of rice on which koji is propagating

Back to sake. Sake is brewed from white rice stripped of its husk. There can be no malting, so the starch-chopping enzymes must come from somewhere else. Enter the cooperative koji. The dark-green spores, sprinkled onto steamed rice, graciously provide the necessary enzymes for saccharification. There are many enzymes involved in this process. Some act to create fermentable sugar (glucose), others act more to create sugars that will not ferment but will instead affect texture and flavor in a sake.

Koji production (known as seigiku) is at the very heart of the sake-brewing process. The leverage it holds over the final product is immense. From a good beginning all things flow naturally, and so it is with koji. Koji is cultivated in a special room in the kura (brewery) called the koji muro. When ready, it is mixed with more steamed rice. Initially, yeast and water are added here. In later stages of a batch, koji is transferred into the large tank within which the sake-to-be is fermenting away. It continues to do its sugar -making work, while imparting the effects of its own sensitive production, until fermentation is finished.

As an example of how sensitive yet powerful koji can be, I once had sake presented by the brewer with an apology: “Look, we just rebuilt our koji muro last year. The wood used for the walls was not quite as ready as we thought, and you can unfortunately taste the cedar wood in the sake.” Sure enough, delicious though the sake was, the faint essence of cedar was evident in the flavor and fragrance.

In general, the koji-making process takes 40 to 45 hours. During this time, the developing koji is checked and mixed constantly to ensure proper temperature and moisture, as well as an even distribution of both. As the koji mold works its way into the center of the steamed rice grains, heat is generated. Different temperatures are ideal at different stages of the process. Not only that, but these ideals will change depending on the sought-after flavor profile. The type of rice, pH and mineral content of the water, and a myriad of other things affect the way koji is made as well. These variables compound to create a process that is more art and intuition than science.

When koji is ready for use, it looks like rice with a small amount of white frosting on each grain. The smell and taste are slightly sweet, as might be expected. There is a characteristic light chestnut-like aroma that wafts wonderfully up.

In response to the demands of the times, there are several manifestations of automatic koji-making machines. Some of these are fully automatic; insert ingredients here, stand back for 42 hours, here’s your kooji. Others allow much more human intervention, some being only closed-loop temperature controlled tables. Even robotic-finger kooji mixers are out there. All of these work well; some better than others. On the quality-versus-labor-saved curve, these score very high indeed. But it is interesting to note that almost every kura in the country makes kooji for their best sake by hand.

The yeast

Importance of Yeast in Sake Brewing

The importance of yeast in the production of sake is extremely important, as yeast influences many elements of sake taste, most noticeably sake fragrance. And since our sense of taste is highly influenced by (if not dependent on) our sense of smell, this is crucially important. Indeed, the proper tasting of sake requires a well-developed sense of smell. There is the initial sniff, noting the general fragrance of a sake. Then comes the fukumi-ka, or the fragrance that arises as you hold the sake in your mouth and breathe. There is also the modori-ka, a third fragrance that becomes discernible immediately after you expel or swallow a sip. Yeast will affect all of these.

What is Yeast? What Does it Do?

Yeast converts sugar to alcohol and carbon dioxide. It is the heart of the creation of all alcoholic beverages. But different yeast strains will produce different things, like esters, alcohols, and acids and other chemical compounds that affect the nuances of fragrance and flavor.

Each yeast will give rise to its own specific array of chemical compounds, with scary names like ethyln caproate and isamyl acetate. These will be present in varying quantities, depending on the choice of yeast and the successful progress (or lack thereof) of the fermentation. Which esters, alcohols and
other compounds are produced are highly dependent on the temperature at which fermentation takes place. All of this will help to determine the character and nature of the sake. In this way, the choice of yeast also directly affects flavor.

Are All Yeast the Same?

How does one strain of yeast physically differ from another? There are many ways, but not all are so obvious. It is often not simply a matter of size or physical appearance. In fact, when the cells of two yeast strains are set next to each other in a microscope, the average person is not likely to be able to tell the difference.

The differences are more evident in other things Like the length of the life cycle of the yeast: how long will it work before becoming dormant, or how robust or fickle it is against alcohol and/or temperature.Which alcohols, esters and other things it tends to give off as by-products of its life cycle during fermentation is of course, another important factor.

How is Yeast Developed?

Although we speak of a yeast being “developed,” it is more a matter of being isolated. The process of coming up with a new, specialized yeast strain, usually takes about three years, and is actually a kind of reverse engineering.

Yeast is usually isolated by starting with a tank of sake being made. It may be one in which many, many strains of naturally occurring (i.e. floating in the air) yeast strains were allowed to initiate the fermentation. Some of the thick foam on the top of the moromi (the fermenting mash) is taken and analyzed. This foam has the highest concentration of yeast cells in the tank. If the sake comes out well, the strain of yeast that is most populous is isolated and reproduced for further study. If it continues to demonstrate the desired qualities, it is made available on a larger scale.

History of Yeast in Japan

In the early 1900s, the Central Brewers Union first began taking pure yeast strains that had been isolated (usually by larger breweries from particularly good tanks of sake) and making them available to kura (breweries) across the nation in pure form, usually in small glass vials. These yeast strains have since been assigned numbers by the Central Brewers Union.

Common Yeast Strains

At present, they are up to number 15. Each one has its own special qualities. Yeast #1 through #6 are no longer in use, as apparently the acid produced was too strong.

Yeast #7, #9, and #10 are perhaps the most important these days. Yeast #7, discovered by Masumi of Nagano, is the single most commonly used yeast in the country, with its mellow fragrance and robust strength during fermentation. Yeast #9 is the most common yeast for ginjo-shu, due to its wonderful fragrance-creating abilities, and fairly healthy constitution during fermentation. Yeast #10 produces a lower-acid, fine-grained flavor in sake, but is a bit fickle at all but the lowest fermentation temperatures.

More recently, Yeast #14 (which is low in acidity with lots of pears and apples in the fragrance) and Yeast #15 (which is very fragrant but not of such robust constitution) are often seen used in finer sake, especially in particular regions.

There are, on top of the publicly available yeast strains, dozens of others that are used on varying scales throughout Japan. Many of these are proprietary, having been developed by kura and used only by them, or more commonly, developed by prefectural brewing research institutes and used by kura in that prefecture.

Many of these are wonderful indeed, and go well with the water and rice of that region. A few examples of this include F701, also known as Utsukushima Yume Kobo from Fukushima, the wonderfully fragrant Alps Kobo from Nagano, and HD-1 and NEW-5, which help Shizuoka sake be the wonderfully drinkable brew that it is.

And finally, no discussion of sake yeast would be complete without mention of the awa-nashi kobo, or foamless yeasts. Yeast #6, #7, #9 and #10 all have cousins that do almost an identical job without producing the massive amounts of foam that rise and fall and breathe majestically throughout the course of the fermentation. These are designated by adding 01 to the number. For example, #901 is a foamless version of #9.

Why foamless? This saves hours and hours of grueling cleaning time, scraping the remnants of the foam from the side of a tank before starting the next batch. Also, since a third of each tank must usually be reserved for the rising foam, more sake can be brewed with less space using such awa-nashi yeast.

However, some experts say that the these foamless versions are not quite what their bubbling cousins are, in terms of the final product. Fragrance and flavors are not quite as refined, although they may be 99 percent of the way there, say some. This is somewhat unsubstantiated, and may be nonsense. It is most likely affected by preconceived notions, but such talk has been heard.

Often these yeasts will be given working names, names that are more romantic than a simple number. One example given above is the F701 from Fukushima, known much more commonly as the Utsukushima Yume (dream) Kobo. Others include mighty #9,also known as Kumamoto Kobo, in honor of the prefecture from which it originally comes (more specifically, from the kura that brews the fragrant and very fruity sake called Koro. Number 10 was discovered by a gent named Chikara Ogawa, so that it is often called Ogawa Kobo (especially in northern Japan, where it was isolated). Number 14 is often referred to as Kanazawa Kobo, and #15 is commonly known as AK-1, for Akita Kobo, both in recognition of their origins.

Why Pay Attention to Yeast?

Yeast is one of the newer developments in the sake world that we can all follow with interest. Over the last ten years or so, dozens of new yeast strains have been developed and come into use. This has been one of those great technical advances in the sake world — one factor that separates great ginjo of today from the run-of-the-mill sake of yesteryear.

Although it may not make much of a difference once you are sipping, learning to identify the qualities of a yeast strain and searching for and comparing fragrance and flavor profiles can be extremely instrumental in improving your palate. It can also simply be a lot of fun.

More and more commonly, especially for decent sake, the yeast used is listed on the bottle. Be sure to look for and try to identify the various special qualities of the various yeast strains.

It is also interesting and important to note that yeast development is one area of progress that has taken place outside of the actual brewing process, yet still affects the final product greatly. In other words, great sake might be brewed using a brand new yeast strain, but the actual brewing process still relies on old hand-made ways that eschew modern machinery.

The water

Suwa water fallsSake is, at first glance, a simple creation. The main ingredients are water, rice, koji, and yeast. Pristine and uncomplicated. But things get a bit more involved just beneath the surface. Water is an appropriate analogy of the apparently simple yet inherently complex nature of sake brewing.

The popularity of bottled and spring water over the last few years attests to the difficulty of maintaining a pure water supply. A quick discerning sniff of the ordinary tap water of many cities can crinkle the nose of even the most insensitive of dullards, especially when compared with fresh spring or well water.Imagine if the delicate flavor components of sake were to be made to compete with that onslaught.

The Role of Water

Sake in its completed form is about 80% pure water. Before it arrives at that final manifestation, however, it is exposed to oceanic amounts of water in each step of the brewing process.The rice is washed, rinsed, and soaked before it ever gets close to the steaming process. Water is then added to the fermenting moromi in the tanks at each of the (typically) three “shikomi,” or additions of rice, water and koji. Finally, a little water is almost always added at the end to bring the alcohol down from the naturally occurring twenty percent or so to around sixteen percent.

All together, the amount of water that goes into a bottle of sake adds up to be more than 30 times the weight of the rice used. It deserves a bit of attention.

Sake Watering Holes

Water and Earl Most of the traditional sake brewing locations, like Nada (Kobe), Fushimi (Kyoto), Saijo (Hiroshima) and Aizu-Wakamatsu (Fukushima) came into existence partly due to the abundant supply of good water in the region. Chemical analysis was not exactly in its heyday in the 1700′s, but the final product told the story, and everyone rushed to set up shop where success had been proven.

The most famous example of this is the water that rushes down from Mt. Rokko in Hyogo Prefecture into Nishinomiya and Nada. Known as “Miyamizu,” sake made using this water was immensely popular among the elite. This led to the region having more breweries and producing more sake than any other place in Japan, a statistic which still holds true today.

Eventually science caught up to intuition and experience and found ways to determine what exactly makes “good water” for sake brewing, as well as what does not. The results of extensive research by sake-brewing research centers, which exist in almost every prefecture, have now become common knowledge to brewers.

What’s Good, What’s Bad

There are a number of elements whose presence is indispensable, without which certain steps of the brewing process will not proceed smoothly. There are also several things that are only detrimental, and either impede the process or adversely effect the sake in other ways.

The Bad Guys

The baddest hombre of the bunch is iron. Iron will darken the color of sake and adversely affect its taste and fragrance. This happens because it chemically attaches to the center of a normally colorless compound attached to an amino acid produced while the koji mold is being made. Also, as sake ages, the residual sugars react with amino acids present to change the flavor and smell, and the presence of iron hastens this reaction.

Manganese plays a different but equally despicable role. When sake is exposed to light, in particular ultraviolet light, manganese promotes a chemical reaction that will discolor and de-luster the appearance of a sake. In direct sunlight, this change can be seen in less than three hours. Although there are others, these are the main two culprits in water that would negate candidacy for sake brewing.

The Good Guys

Then there are the good guys; elements and compounds whose presence we cannot do without. In particular, potassium, magnesium and phosphoric acid are necessary to aid the propagation of the yeast in the “shubo” (yeast starter), as well as in the proper development of good “koji”. If these are not present in sufficient amounts the yeast cells will not multiply as well or as quickly, throwing off the timing off of the entire fermentation so that it can not be properly controlled.

One of the problems here is that potassium is water soluble, and can be washed away during the rice washing and soaking processes if the kurabito (or brewery workers) are not careful. A similar hassle exists with phosphoric acid, as it is generally attached to fat and protein molecules. It must be removed from these, and the bonds are broken by enzymes donated by the kind koji, thereby freeing it up to be used by the yeast. This shows how tightly the various aspects of the brewing process are intertwined.

To sum up, potassium, magnesium, and phosphoric acid help vigorous yeast propagation and also assist in koji development. Iron and manganese, on the other
hand, adversely affect the flavor, aroma, and color of a sake in a relatively short amount of time.

Where Do Brewers Get Their Water?

Leaving the chemical chicanery behind, where do kura get their water? More of it comes from wells than any other source. The stable temperature of deep well water gives it consistency,although the individual qualities of a well vary with depth and the land.

Rivers flowing from the mountains as well as lakes and other bodies of water are also used, but the less-than-positive changes in the environment over the last century or so have rendered many of these useless. Which is not to say this practice is completely obsolete. Many kura brag about their region’s “meisui” (famous water), insisting that it is one of the secrets of their fine brew.

Naturally, water can be chemically altered and synthetically produced to specifications, so many kura take that route. Still others use local tap water, and filter it or alter it as is necessary to fit their needs.

As a general classification, water for brewing is often referred to as “kosui” (hard water)or “nansui” (soft water), with several monikers that reside somewhere between those two extremes. Although both kinds of water have the potential to make wonderful sake,the brewing methods are subtly different for each. The famous Miyamizu of Kobe is kosui, whereas nearby Fushimi water in Kyoto is nansui. Both Hiroshima and Fukushima have, in general, soft water.

Among sake brewers, water is more often referred to as “tsuyoi mizu” (strong water)and “yowai mizu” (weak water). This refers to how well the water promotes fermentation.And just because the water is “weak” does not by any stretch mean it is not suitable for brewing; it just indicates that the timing of certain steps will be different. Although the correlation is not completely direct, hard water is generally strong water.

Lately, in the barrage of information that has come to appear on sake labels, the type of water used in brewing is sometimes listed.
