From whence does the added alcohol come?

In recent years, the line between junmai-types vs. non-junnmai-types divide seems to be strengthening, in many senses. One such sense is sake style. Brewers that focus on junmai seem, at least to me, to be making the richer and fuller styles that junmai types can be, and those that make non-junmai, i.e. added-added alcohol types, seem to be making lighter, more aromatic and seamless sake styles that added alcohol affords.

While there is a lot of information out there on these two divisions of the sake market, here is a semi-brief synopsis. About 80 percent of all sake has pure distilled alcohol added to it just after fermentation. Water is later added to bring the alcohol back down, so it is not really fortified. When alcohol is not added the term junmai is put on the label.

So junmai-shu, junmai ginjo-shu and junmai daiginjo-shu are the three premium types of rice-only sake. Honjozo-shu, ginjo-shu and daiginjgo-shu are the three types of added alcohol premium sake. For the 65 percent of the market that is non-premium sake, this addition of alcohol done for economic reasons. For the 15 percent of the market that is premium and non-junmai (honjozo, ginjo-shu and daiginjgo-shu), this added alcohol is done for good technical reasons: it helps extract flavor and aromas, and predisposes the sake to time in the bottle.

In recent years, the junmai types have grown in popularity, but the non-junmai types have been a bit maligned, unfairly so in the opinion of many, myself included. Those that are anti-added-alcohol say they can taste it, it gives them a hangover, it is somehow cheating, and other unfounded arguments. While a rant is not the aim of this article, the topic is one about which many in Japan feel passionate.

However, interestingly, in blind tastings many ostensibly dedicated junmai fans will choose non-junmai sake over junmai sake. This I have seen again and again. But like I said, this is not intended to be a rant.

Beyond the untenable arguments above, though, there are a couple of valid positions. Namely, whether or not sake is made from rice, and whether or not the ingredients are domestically sourced. For example, brewers must list on the label the source of rice. They are permitted to use imported rice (very, very few do, and only for very, very cheap sake), but in the ingredients list it must say “domestic rice” or “imported rice.” The same stipulation is not, however, applied to added alcohol.

Almost without exception, the alcohol used when making non-junmai sake is roughly distilled from sugar cane, imported into Japan, and then distilled again for purity. By the time it gets to the brewers it is pure ethyl alcohol, blended with water for safety reasons. So it is not made from rice, and it is not from Japan. To have a product like sake – the national drink of Japan – which is known as a rice-based product – be made with something other than rice, and other than Japan-based ingredients can be a sore point with some folks.

Again; not me. I enjoy sake completely unfettered from such concerns. Perhaps I am just a hedonistic simpleton. But I digress.

So yes, junmai types are growing in popularity in Japan, but so is an understanding of the very positive aspects of added alcohol sake.

And related to all of this: I recently saw in an industry publication a very interesting idea that has arisen of late.

In order to make premium sake, inspected rice must be used. Inspection ensures certain levels of quality in the rice, which will vary from rice to rice. And in any event, rice in general is just expensive in Japan.

But what if the alcohol used for making non-junmai were to be distilled from really, really cheap rice – broken stuff or rice that did not pass inspection. Again, since it is taken down to being pure ethyl alcohol, the quality of the original rice should not matter.

Surely this is more expensive than sugar-cane based alcohol. But the other side of the coin is that by using this, the entire product can be rice based, and one hundred percent domestic. Surely this will help the agricultural sector as well, since even schlock rice has a use.

What I am curious about is, if premium sake were to be made using added alcohol, but that alcohol was made from domestic rice, would the junmai jihadists concur on its validity as sake? Certainly the quality would be there, or at least, there is no technical reason it would not be so. If so, the idea holds potential for the sake world in bringing non-junmai types back to the fold, and the rice-growing industry would benefit as well.

Making non-junmai using alcohol distilled from domestic rice, even domestic schlock rice, would not be cheap. Surely it would be more expensive than using imported sugar-cane based alcohol. But just as surely there is a market for such products.

And, equally as surely, there is a sector of the market that does not care, only cares about price, enjoys cheap sake – and deserves to have it. So to insist all sake be made in that way would not be fair to all brewers or all consumers. But I see a compromise.

What if cheap sake were to continue to use imported ethyl alcohol and premium sake, i.e. honjozo, ginjo and daiginjo, were to be limited to added alcohol made from domestic rice? This could be indicated on the label, just like the source of the rice.

While I think this is a great idea, it is clear there would be humongous challenges. It would be hard to regulate or enforce. Brewers might be reticent to try this for a handful of reasons, from technical to image-related to economic. Many consumers might not be convinced, won over, or trusting. They may choose to stick with their junmai-only mentality – which of course is their prerogative.

Furthermore, sake brewers are – for the most part – an intelligent lot. Something tells me that someone somewhere along the line has thought of this. If it has not been realized, there must be a good reason. As an indication of this, there are a few brewers that distill their own junmai-shu and use that as the alcohol they add to their sake. So some experimentation has taken place, but nothing remotely resembling widespread adoption.

Finally, as almost all premium sake that is exported is of the junmai varieties, this is not a problem that will resonate with many. It is not exactly rocking the sake world. It is, however, an interesting potential solution that may present opportunities to a handful of challenges at once. It will be interesting to see how it all plays out over the next few years.

How many producers, how much sake?

As interest in sake grows around the world, naturally enough more and more people express curiosity about the sake industry at its source and origin: Japan.

There are many angles from which the industry can be viewed and analyzed. Certainly sales growth and production numbers are one such metric. And as important as they are, those numbers are in constant flux these days. Sales of premium sake grows but overall production still drops as the older generation that was the main market for inexpensive sake gradually passes on. Certainly the growth of premium sake is a more appealing number, and surely it is a better indicator of what to expect in the future.

Another metric, one that is more tied to the traditional infrastructure of sake brewing, is the number of brewers active in the industry. And even these numbers can be confusing and open to interpretation.

For example, one survey on sake exports mentioned that of 1613 companies surveyed, 1526 responded. However, there certainly are not 1613 active sake brewers. It makes more sense when we realize that some companies that just bottle product also need licenses. Furthermore, there are a good-sized handful of kura that are no longer brewing, but refuse to throw in the towel, and so are “taking a break” from sake-producing activities. And, there are some companies – I would estimate ten percent – that have more than one facility, each calling for a separate license. So bundle all those together and perhaps we will get to 1613 or so.

Another survey by the National Tax Administration determined that during the brewing season that ended in July of 2015, there were 1225 sake-brewing facilities, down 11 from the previous year. However: there are breweries in existence that do not actually brew themselves, for any one of a myriad of reasons. They instead outsource it from factories that are under-capacity, and bottle it and sell it as their own. Some do this with only part of their lineup, others do it for all the sake they sell.

Practices like this are good for small companies with a local market but that might not have the manpower or capital to actually produce it anymore. It can also be helpful to the outsourcing company as well. So while not everyone would enthusiastically support this sector, it fills a need.

When I arrived in Japan in 1988, there were 2055 kura selling sake. Now there are 1225. So we are down 830 sakagura in 28 years.

Based on estimates from traveling the country, working in the industry, and actually counting breweries all around the country (I have a lot of time on my hands…), all observations indicate that there are probably close to 1000 sake companies actually making sake. And that may be a high-end estimate.

So, how many sake breweries are there in Japan? About 1600 with licenses, about 1200 selling product, and about 1000 actually brewing the stuff.

Amongst those thousand, how much sake is being made? About 550 thousand kiloliters a year (of recent). Let that number sink in: over half a million kiloliters. Of that, 13 percent is ginjo (including its four subclasses), and 12 percent is junmai-shu. Interestingly, just a scant 20 years ago, both ginjo and junmai were but four percent of production each.

How much rice did the industry use last year? About 250 thousand tons of genmai (unmilled rice), or 164 thousand tons of milled rice. Let that number sink in too. The average seimai-buai (milling rate) was 65 percent.

Of the 1225 kura out there, 41 are considered large, i.e. 1300kl or more. All 41 of these companies export sake. Of the small companies, the tiny craft brewers sector, 93 percent export sake. But still, 70 percent of all sake exports come from the big 41 kura. Indeed, the polarization of the sake industry is very interesting.

In spite of all this, only three percent of all sake brewed is exported. Only. Three. Compare that with the twenty to thirty percent of French and Italian wines that are exported from those respective countires. Or, compare that with scotch whiskey, for which 90 percent of all production is exported. Wow. Either we have a lot of catching up to do (the sake glass is half empty!) or the sake future is so bright, we gotta wear shades when we drink it (the sake glass is half full!).

Either way you look at it, start by filling the sake glass up back to the brim, and enjoy it. If everyone does that, the sake future is indeed a bright one.

The 2015-2016 brewing season is drawing to a close. This month and next, most of the 1200 brewers in the country will be pressing their last batches and cleaning their tools, then closing shop until the fall of this year. As I look back at the kura I visited, one particularly interesting place sticks out in my mind.

In February I visited a brewer making a sake called Kirei, written with the characters for turtle and age. Tortoises live a long time, hence the auspicious connotations. It is a tiny company in Nagano called Okazaki Shouten, with the brewing being done by two people, the husband-and-wife team that own it. They do, in fact, have a little bit of part-time help along the way.

Obviously, they cannot make very much sake. In fact, it is a true micro-kura, with their yearly production being only 100 koku. A koku is a traditional unit equaling 180 liters, so that means they only make the equivalent of 10,000 large 1.8 liter bottles, or 2000 nine-liter cases.

There are hundreds of such small kura around Japan. Such places may barely eke out an existence, which is just fine by (at least some of) them. Their sake might range from “fair to middling” or it might be great like Kirei, and they may in fact have other sources of income. It doesn’t matter. They love doing what they are doing. And that is all that matters.

However, in the case of Kirei, their smallness has not crimped their quality at all. Not. At. All. On the contrary, the reason they are so interesting is that last year their sake was the top sake in the government-sponsored tasting for the Kanto-Shinetsu region of Japan, which includes not only venerable Nagano but revered Niigata Prefecture as well. And Shinshu Kirei was tops. Wow. That is impressive.

But with such a small production, obviously there is not much of this sake to go around. Certainly the opportunity is there for them to expand, grow, develop, invest, hire – and all that stuff. Many would think they would ride this wave, and certainly they could. Some folks might think that any businessperson in his or her right mind would do so, right?

Sure. But sometimes it’s not about that.

As Okazaki-san, husband-half of the dynamic duo, led me around the kura, the conversation naturally moved in that direction, and of his own accord he addressed the questions that he must get so often get asked. Why not make more sake? Why not grow, develop, expand?

“I dunno,” he begins. “Sure, we could hire someone and increase our production at least a little bit. But the risk is for a company of our scale is huge. This new hire would then be a full one-third of our labor. Should something happen, we would immediately lose a huge chunk of our staff.”

As we moved amongst the two rows of tanks of moromi (fermenting mash) they use in the small fermentation room, he continued.

“But it’s not only that. If we were to hire people, I would necessarily need to go into management of our staff, and do other things related to maintaining and managing growth. While that is all perfectly valid and good work, it is not what I want to be doing day-to-day.

“In other words,” he summed it up, “if we try to grow much, I will not be able to look after the moromi.” So maybe he loses out on a chance for growth, but he’s going to be happier doing what he loves, and that energy will get conveyed into his sake.

Very cool. They know what they want to be doing and are aware of the consequences of their choice to do that, as well as those of choosing something different – to grow. And they daily make a conscious and rational decision: they choose the merits of staying small.

I’ll drink to that.

Note, there is also a brand Kirei in Saijo in Hiroshima. The brand name and characters are the same as the company introduced above, so to eschew confusion they often add the traditional name of Nagano Prefecture, Shinshu, to the name of this sake, i.e. Shinshu Kirei.

Note, too, their sake is light and young, with great balance and breadth rather than just impact, and perhaps more defined by banana and melon aromas than the wilder fragrances of many modern ginjo sake.

Yamada Nishiki. One cannot tread far into the sake world without encountering the name of the most important sake rice in existence today. Yamada Nishiki.

It is the “king of sake rice,” there is no challenger in sight. It is the best choice for top-grade sake for a handful of reasons, and it is as expensive as it deserves to be. Yet, while it is admittedly deserving of its reputation, it can be a bit “in your face” sometimes. Yamada this and Yamada that, yada yada yada. (Yamada yamada yamada?)

But, what is it, really? What is behind its fame and success? From whence did it come and when? What, f’gad’s sake, is the big deal? I mean, it’s rice, right?

Indeed, it is just one variety of sake rice, of which about one hundred exist today. And it is the most grown sake rice, with about 1000 of the 1200 kura in Japan using at least some. But note, it is not by any stretch of the imagination the only game in town. There are plenty of other sake rice varieties that are interesting and lead to outstanding, deliciously enjoyable sake. The point of this article is not to worship Yamada Nishiki nor to idolize it, but to present some background as to what it is and why it is.

Taking a half-step back, let us recall that sake rice is as different from table rice as good wine grapes are from the fruit we buy at the grocery store. It is larger, has less fat and protein, and more starch which is centered in the grain, thus allowing the offending components to be more easily milled away and removed from the equation.

Most sake, in fact, is not made using sake rice. The 65 percent of the market that is non-premium (if enjoyable!) sake is made using much less expensive table rice, i.e. rice for eating. And much of that is perfectly enjoyable sake. Even some premium sake is also made with table rice; it is possible to make very decent sake from such rice.

However, the truth is that it is immensely easier to make good, tasty sake from proper sake rice. And not only is most premium sake is in fact made using sake rice, but in order to make great sake you must have great, proper sake rice. End of story. Full stop.

Furthermore, the better the sake rice the easier it is to make good sake, and great sake. Even within the realm of sake rice – and even within the realm of one variety of it – there are greater and lesser producers, harvests, regions, fields and grains.

Better might mean larger, more starch and in a manageable position and a manageable size  within the grains, solubility that is just right, and more. Of course, price will vary with that quality, and the quality of the grains in even one single field will vary too. (They will be separated by size and other criteria, and a good or great field will have more great grains than a ho-hum or mediocre one.)

So wuzzup with Yamada Nishiki? Yes, it is big, even for sake rice. And it has an ideal-sized and centered starch center (known as a shimpaku, which means “white heart”) enabling it to be easily milled so as to remove the fat and protein and leave the starch behind.

During fermentation it dissolves readily – but not too readily. It is harder to grow than regular rice, but not nearly as challenging as some other types of sake rice. And, of huge importance, it is predictable. Brewers know how it is going to behave – or at least, a bit more so than with other rice types. One reason for this is that it is so widely used that there is data out the wazoo.

What does sake made with Yamada Nishiki taste like? It has breadth and depth, and flavor that billows into the expanses of one’s palate. It has a wide range of flavors that somehow work together well, often with ideal levels of sweetness and umami. However, it is extremely important to remember that the range of flavors and aromas is massively wide, since in the end rice is only half the story. The way the brewer manipulates, directs and coaxes the rice through the production process is, as they say, “the rest of the story.”

Just like any agricultural product, each variety of sake rice grows better in some regions than others, and has climates and soil types within which it thrives. Often these can be small and vary with just a short distance. And the best Yamada Nishiki undoubtedly comes from Hyogo Prefecture in western Japan, within which sits the city of Kobe.

Even within Hyogo there are regions, villages and even plots of land that yield superior Yamada Nishiki rice. And the two best villages in the region, country, world and Universe for Yamada Nishiki are Yokawa and Tojo. If you remember two place names related to top-notch Yamada, let it be those: Yokawa and Tojo. But as is always the case with sake, it’s not that simple.

Yokawa is a township in the city of Miki in Hyogo Prefecture. However, Tojo no longer exists, at least not officially. (So, yes, you are being asked to remember the name of a place that no longer exists. Ain’t sake fun?)

Tojo was a region that was annexed during a spate of consolidation of sparsely populated municipalities that took place in Japan a few years back. So now, what was the township of Tojo is currently the city of Kato. However, the Yamada Nishiki from Tojo was so damn good that it had branding power. So the growers of the region formerly known as Tojo banded together and registered “Tojo-grown Yamada Nishiki” as a registered trademark. So Tojo-grown Yamada Nishiki exists even if Tojo itself no longer does. Ain’t sake fun?

Why does it grow best here? A veritable plethora of reasons! The soil is rich in minerals. The climate is perfect, and the Rokko mountain range to the south isolates the area just enough to make the difference between daytime and nighttime temperatures significant, which sake rice prefers since this climactic condition helps the starches accumulate in the center of the grain.

Yokawa-cho in particular is high in elevation, and the growers there use rice fields cut into the mountainside like a set of descending shelves, which lets the water flow down through the fields smoothly.

From whence did it come? Yamada Nishiki was created in 1936 as a crossbreed between two other rice strains, one being Yamadaho. This was also a great sake rice, but was too tall and lanky and frustratingly difficult to grow. So the prefectural agricultural research center at that time (which has since morphed into a broader organization but still exists in spirit) crossbred it with a shorter, sturdier sake rice called Tankan Wataribune. This made the progeny that became Yamada Nishiki more manageable and better in many ways.

Sake rice can be shipped all over the country, and brewers from northeast to southwest seek Hyogo-grown Yamada Nishiki for their top grades of sake. Not all, mind you, but many. However, Yamada Nishiki is also grown in many other places in Japan, some almost as well as Hyogo. In fact, 33 of Japan’s 47 prefectures grow at least some Yamada Nishiki, although a full 60 percent of all grown comes from Hyogo.

Interestingly, though, Yamada Nishiki seeds have never officially left Hyogo Prefecture. This is significant because, in order to put a premium grade of sake on the label, a brewer must use rice that has passed a certain level of inspection. And in order to have rice inspected, the rice must be registered with the local authorities, and the seeds must also be sourced from a proper source. It is all a bit gray, sometimes even to sake producers.

So if the seeds never left Hyogo, how do other prefectures know that what they have is the real thing? And why do other prefectures recognize it? Hm. Not sure about that. Let’s chalk that up to the mystique suffusing this venerable rice and sake in general.

Also, credit must be given to the largest sake brewers in the country, the current-mass producers of sake in the Nada region in Hyogo. It was they that drove the production of this standout rice from the start. When their technology began to help make decent sake with less expensive rice, Yamada Nishiki became more available to the rest of the sake industry. As is too often the case, their significant role may be unappreciated.

All of the above combines to create the legend, the reputation, and the mystique that surrounds and suffuses Yamada Nishiki. So next time you come across it – and that should not be long if you drink sake on anything remotely resembling a regular basis – bear in mind it is not just another rice. It’s Yamada Nishiki.

Although brewers have been working on making better and better sake for, heck, 900 years or so, the last century or so has been fairly exponential in terms of gains in sake-brewing methods and technology.

Even though we can say that, for many centuries, sake-brewing has remained basically the same, in fact there have been many changes. From just about 100 years ago, technology and science began to augment the well-entrenched experience and traditions of brewers.

Often, we hear that ginjo sake is leaps and bounds better than the sake of yesteryear, replete with complexity of flavor and fragrance that allow it to be appreciated as a such a premium beverage. Let’s look at some of the more significant contributions over the last century to what has become today’s sake.

1568: Brewers in Nara began to heat sake up to about 65C to “remove the evil humours,” thus pasteurizing and providing stability to sake. Louis Pasteur lent his name to this process centuries later, and he got all the credit.

1895: Sake yeast was first isolated. Until this time, yeast cells were allowed to simply fall into the vat from the ambient environment. Finally, brewers were able to see just what the yeast cells looked like, and to study their life cycle.

1904: The Ministry of Finance forms the National Sake Brewing Research Center. Here, research geared toward helping producers make better sake continues to this day.

1910: Sokujo moto, the fast-starting yeast starter, is developed. Until this point, creating the moto yeast starter was a long, exhausting process and an extremely labor intensive part of sake brewing. When it is discovered that the result of the techniques was to create a bit of lactic acid, researchers found that putting a bit of pure lactic acid in at the beginning accomplished the same thing, saving significant labor and time.

1911: The first Shinshu Kanpyoukai, or New Sake Tasting Competition, was held. The longest-running competition of its kind in the world, this yearly tasting continues today and has driven major advances and trends in sake profiles over the years.

1923: Stainless steel tanks begin to replace traditional cedar tanks. As the woody flavor imparted by cedar tanks can be strong, sake brewed in stainless steel tanks is now free to express a myriad of new and delicate flavors, fragrances and nuances. This was huge.

1933: Modern vertical rice milling machines are introduced. The condition of the rice after milling “how much it has been milled, how much heat was generated during milling, how many of the rice grains fractured or broke” affects every single step on down the line. With this major advance, rice could be polished more accurately, carefully, and efficiently. This was also extremely huge; it eventually led to the era of ginjo.

1936: The mighty Yamada Nishiki, the king of sake rice strains, is born. It is created as a cross breed between two other sake rice strains, Yamadaho and Wataribune. Although expensive and relatively hard to grow, Yamada Nishiki is the most widely used sake rice, especially when brewing ginjo-shu. There are other rice strains that make character-laden and wonderful sake, but Yamada has yet to be dethroned.

1943: The sake classification system of Special Class, First Class, and Second Class is created by the Ministry of Finance. All sake is designated as one of these three, with First and Special classes requiring government tasting and certification, and (of course) higher taxes. This system is later abolished in 1989 for several reasons, one of them being that many brewers simply did not submit their sake for certification, thereby keeping prices of great sake lower. As such, the system lost much of its meaning.

Also in 1943, it became obligatory to add distilled alcohol to sake at the end of the brewing process. The obligation was removed in 1946, but brewers were not forced to stop this practice. This can enhance flavor and fragrance and stabilize the brew, but can also be used to simply produce cheaper sake.

1946: Yeast Number 7 is discovered and isolated by Masumi Brewery ofNagano. This yeast is still today the most used yeast in the country. That year, Masumi sake wins every single award in sight for their sake.

1953: Yeast Number 9 is discovered in Kumamoto Prefecture, by the brewers of Koro sake. Yeast Number 9 produces fragrant and fruity sake, with a decent acidity. It is today the most widely used yeast for ginjo-shu, although it has a lot of competition these days. A biggie on the flavor and fragrance fronts.

1968: The first post-war junmai-shu (sake brewed with no added distilled alcohol, nor any additives of any kind) is brewed. Although two brewers, one in Kyoto and one in Kumamoto, claim to have done it first, it marks a move of great significance (i.e. a biggie) by members of the brewing world toward quality and better sake, and profit margins be damned.

1974: National sake production hits an all-time high. Unfortunately, since that point it has been mostly downhill, with production volume decreasing almost every year since then.

1975: The Jizake boom begins. Jizake is a vague term that means sake from smaller brewers in the countryside, or at least sake not from large national brands. Such sake began to gain popularity for its supposed character and regional distinction.

1981: The Ginjo boom begins. Premium sake begins to increase in both popularity and production from this point. Even today, while overall sake production declines, ginjo-shu production increases, albeit by very little.

1989-2015: Dozens of new strains of yeast and new sake rice strains are developed and come into use in sake brewing. Many of these are proprietary, and many are kept within the prefecture of origin. These factors alone contribute to a new and wide range of sake profiles.

All of the above have built upon each other to create sake as it is today. But modern equipment and microbiology alone could not have led to the ambrosia that is the sake of this era. Just as much credit must be given to the craftsmen and craftswomen, and their decades of accumulated skill and refined senses. Indeed, their craft deserves much appreciation!

Sake has a long and storied history, going back centuries and centuries. Just how many centuries is a matter of interpretation: exactly when did the rice-based mash look and taste enough like today’s brew to call it sake? The answer likely depends on who is trying to convince whom of what.

But most agree that sake brewing goes back some 1700 years, based on archeological finds that show that the locals were deliberately making an alcoholic beverage from rice. It hardly resembled the glorified ambrosia we take for granted today, but if you want to trace the history of sake, that is where it leads.

We also hear from time to time about kami-kuchi sake. This was made by folks chewing rice a bit and spitting it into a vat around which they stood. The enzymes in their saliva converted the starch into sugar, after which yeast in the air took things from there and converted that into alcohol. Appetizing, iddn’t it?

But really: this is cave-man stuff. There was never a commercial product. No one really made proper sake in this way f’gad’s sake. Nor do any of Japan’s written histories or sake-brewing records mention any such a method. Yet so many writers likes to latch on to it and open stories about sake with references to it. It just makes for good article content fodder, at least the first thousand times you read it; then it just gets old and annoying. But I digress.

Lots of progress was made in the eleventh to thirteenth centuries in Buddhist temples in and about Nara, and that transitioned into the current method of making sake, which has remarkably remained pretty much the same, at least in terms of principles and objectives. Sure, modern machines save labor and cost. And very cheap sake is indeed made using methods that are far from traditional methods that yield stuff that does remarkably resemble sake.

But most premium sake is made in old, hassle-laden methods that have been around for centuries. Modern machines can help avert labor by moving heavy things around. But the assessments at each stage and the on-the-fly tweaking are performed in traditional painstaking methods.

Most breweries are owned and run by families (way over 90 percent are family owned operations) that were once aristocratic and can trace their lineage back sometimes tens of generations. As such, many kura today have long, long traceable histories.

In fact, there are still about 300 sake companies in Japan that were founded before 1800, in other words, that many have an over-200 year history!

Here is a list of Japan’s oldest sake breweries and the area in which they are located. Note, the top ten alone are all more than 458 years old!

10. Ueda Shuzo in Nara, brewers of Kicho, founded in 1558

9. Konishi Shuzo in Hyogo, brewers of Shirayuki, founded in 1550

8. Yoshinogawa Shuzo in Niigata, brewers of Yoshinogawa sake, founded in 1548

7. Shusenkurano in Nagano, brewers of Genbu, founded in 1540

6. Tomita Shuzo in Shiga, brewers of Shichiyonyari, founded in 1543

5. Yamaji Shuzo in Shiga, brewers of Kuwazake, founded in 1532

4. Kenbishi Shuzo in Hyogo, brewers of Kenbishi, founded in 1505

3. Hiraizumi Shuzo in Akita, brewers of Hiraizumi, founded in 1487

2. Sudo Honke in Ibaraki, brewers of Sato no Homare, founded before 1141

1. Imanishi Shuzo in Nara, brewers of Mimuro Sugi, estimated to be over 900 years old.

Currently there are less than 1200 brewers that continue to sell sake, Old Kura

although several hundred more have retained their licenses to do so. There were as many as ten thousand at one point in the early twentieth century. While it may be tempting to focus on how many have disappeared, it is amazing to see that such a traditional industry has survived more or less intact, and is now after decades of decline beginning to turn around gradually.

Let us all do our part! Enjoy some sake tonight with a heartfelt “kampai!” for the history of sake and its oldest members.

Last month in this newsletter we talked about aged sake, and pointed out that, although it is not quite mainstream, matured sake, known as koshu or chouki jukusei-shu, can be extremely interesting. And that is one reason the Nippon Jozo Kyokai, i.e. the Brewing Society of Japan introduced above (BSJ), a while ago began the One-Hundred Year Aged Sake Project.

Just what is the One-Hundred Year Aged Sake Project? Pretty much just what it sounds like it would be: a research project to age sake for one hundred years. Here are some specifics.

The idea was born in December of 2005, as a cooperative effort between the BSJ and the then-ten year old Chouki Jukuseishu Kenkyuukai, or the Aged Sake Research Group. Also, the National Research Institute of Brewing, NRIB, and Tokyo Agricultural University, known less formally as “Nodai,”( the “UC Davis” of the sake world), are helping out a bit as well. The stated purposes of the experiment are (in far less eloquent words than the original text) to “see what happens” and to “learn more about the possibilities related to aging sake.” Yeppir. Pretty much what you would expect.

Most of the sake will be aged in the iconic red-brick building (seen below) in Tokyo that housed the NRIB from 1904 until this year, when it moved to Hiroshima.

The amount of sake progress made within those hallowed red-brick walls is unfathomable. It really is sacred ground to the sake world. The sake aged there will sit on wooden (hinoki, like cypress) shelves with no metal anywhere near them. The rest, stored at Nodai, will be handled by placing the bottles inside metal tanks. Temperatures will be maintained between 15C and 20C.

Each of the 33 brewers participating will submit one 1.8 liter glass bottle, or the equivalent amount in either titanium vessels, or Kutani or Bizen (two types of traditional Japanese ceramics) vessels. Wow. I am not sure why they insisted on those two styles of pottery, but that is cool. Very cool.

And for good measure they have thrown in one bottle of sake made in 1925, already 80 years into its aging, found in a kura in Wakayama.

Along with the one bottle of sake destined to sit a full century, each kura submitted ten smaller bottles (720 ml) to be used at ten along-the-way tastings to be held every ten years. The first of those tastings was held this past November, exactly ten years since it all was laid down. I was fortunate enough to be invited to that tasting, and even if only for the uniqueness of it, the event was fascinating.

Of course, it went beyond the appeal of mere uniqueness, and the aged sake that were presented displayed a fascinating range of flavors, aromas and directions of maturation. It was really difficult to try to assess them all as a whole since the range of aromas, flavors and intensities was mind-boggling.

I am thinking (or rather, hoping) I will be around for another couple-few of these, but will have to defer the tasting of the final round to someone a lot younger than I. Perhaps one of my grandchildren can represent me.

While I reiterate that very little sake is aged, most brewers do not make any aged sake at all, and that long-term aged sake is a totally different animal, I also will again add that it can be very interesting. Perhaps aged sake will be all the rage in 2105.

You can learn a bit more about the Aged Sake Research group here although it is in Japanese. You can learn more about this project itself here, and see a couple of pictures of the site as well.

Yeast is a crucial ingredients in sake.

The three main ingredients of sake are usually given as water, rice and koji, which is steamed rice with a mold grown upon it that converts starch to sugar. But although not usually listed as an ingredient, yeast is crucial in that it converts that sugar into alcohol, carbon dioxide, and many other things that make a sake taste and smell the way it does.

Yeast does and will occur naturally in the environment, but is – with only a couple of exceptions – manually added. More than anything else the choice of yeast determines the aromas of the final sake, although as we have come to expect with sake, it ain’t quite that simple.

There are hundreds if not thousands of yeasts used in sake brewing today.

Tons of ‘em. Oodles and oodles of ‘em. I am fond of saying that “everybody and his brother has a proprietary or special yeast.” Many (if not most) of them are recently developed and are to some degree experimental; if the resulting sake is a hit, great. If not, the brewer may move on to other yeast choices. As such, many are not long for this world. Indeed, few will last the test of time.

Not that it has always been this way. The surge in proprietary and specially developed yeast strains is about 25 years old now, I reckon. Before that the industry focused more on a handful of tried and true yeast strains that have been around for about a century. And before that, everyone depended on their own in-house ambient yeast, which alone could make or break a kura’s reputation.

Where do they come from? With so many out there, obviously there must be multiple sources. But it is probably safe to say that most sake in Japan is made using a yeast obtained from the Nippon Jozo Kyokai, known officially in English as the Brewing Society of Japan.

The “BSJ” has been around since 1906, originally as a group of researchers that had recently graduated from a governmental sake production course.

Their main functions are R&D, and of course stocking and distributing microorganisms, mainly sake yeast. The yeast strains themselves were for the most part discovered in sake breweries around Japan, and most have been around for decades and decades.

They are meticulously reproduced and kept pure year after year, providing stable and dependable fermentation to sake breweries all over Japan. While yeasts can have all kinds of names, those from the BSJ are recognizable by their very simple nomenclature, such as #6, #7, and #9 – which belie their significance in the industry.

While numbers one to five do exist, they are no longer distributed due to what is considered to be excessive acidity. In fact, amongst the handful of yeast strains that are actively supplied, the main ones to remember are numbers 6, 7, 9, 14 and 18-01. They were named in order of discovery, and the higher the number, the more ostentatious the aromatics. (Sorta. It’s not quite that simple, but for sound-byte purposes, that’ll do in a pinch.)

In terms of how these are reproduced, it varies a bit from yeast to yeast. But basically, stock yeast cells are put into an environment that encourages reproduction. Kind of like a love hotel for yeast, I guess. The resulting yeast cells are harvested, and washed with sterilized water, analyzed for purity and quality, and then bottled in little glass ampules.

Yeast cells mutate very quickly, and so the cells must be checked to be sure

the compounds they produce and the other characteristics are true to the original. Otherwise the acids, esters and alcohols could change, and brewers would end up with sake that is totally different from what was sought.

Once these ampules arrive at the kura, brewers will then use them by pouring the pure yeast directly into a yeast starter, or alternatively, giving the yeast cells a kick-start via a nutrient solution of koji and water. There are also other ways, of course.

However, as alluded to above, the BSJ is not the only source of yeast. Far from it! Many prefectures have their own research organizations that develop yeast strains for use by local breweries, and many breweries have their own proprietary strains as well. “Developing” yeasts really means isolating them from amongst countless strains naturally occurring in the air. (No genetic modification is done at all.)

But for almost all of these modern yeast types, rather than being a yeast that rose naturally to the top both literally and figuratively, they were the result of an active search for particular qualities like fruity aromas. Certainly there is nothing wrong with this; it is still a natural process. But many of these more modern yeast type are comparatively ostentatious in their aromatic profiles, with apple and licorice and tropical fruit more apparent than the banana and melon of olde.

Furthermore, many of these new whippersnappers amongst the ranks of yeast do not tolerate time well, in other words, the sake made using them changes comparatively quickly in the bottle, sometimes leading to bitterness in the background of the sake.

This is not to discredit or criticize their use, nor the sake to which they lead. Much of it is wonderful and popular, to be sure. The only point here is to highlight some of the differences.

However: it does seem to be that the modern yeasts, for all their lively aromatics, are very slowly falling out of favor. Perhaps a more correct way to say that is that there seems to be a slow but evident return to the more classic yeast types, in particular #6, #7 and #9, with a dollop of #14 in the daiginjo department.

Is this clearly measurable? Nah; not yet. It is still a fledgling trend. And it may not gather critical mass, and the tendency to use modern yeasts may continue. As such, not much is clear on the yeastern front at all. Vibrant ginjo aromas are still popular, even if less pretentious sake does seem to be making a comeback.

It is important to emphasize again that there is no one superior yeast or group of yeasts. As long as the sake is enjoyable by a significant number of people, anything goes. “It’s all good,” as they say. But the slight trend toward the classics, both in terms of aromas, choice of yeast, and brewing methods such as kimoto that tie in well with more less brazen yeasts, is interesting to observe.

More and more producers are providing yeast information for the sake available both in Japan and overseas. Be sure to take note of this information – and your own observations – as you enjoy sake from here on out. It can only enhance your sake experiences.

It is a rare occasion and ceremony that does not include some sake in Japan, and that harbinger of renewal, New Year’s Day, is no exception. Although sake figures prominently in O-shogatsu (New Year’s) celebrations from morning to night, opening the year with a prayer for health in the form of drinking O-toso is perhaps the most interesting.

In the movie (and play), “A Bronx Tale,” the members of a particular fraternal organization centered around their ethnicity ran a bar into which a group of members of another fraternal organization, this one centered on their preference for two-wheeled vehicles, attempted to enter.

“It’s a private club,” they were told. “You have to leave, you have to leave.”

“But we want nothing more than to have a drink in your fine establishment, sir. We mean to cause no trouble,” came the response.

“Fine,” they were told by the semi-philosophical owner. “You are free to have a drink.”

Well, not five seconds after getting beer in hand, the bar exploded into pandemonium, with the bikers shaking and shooting their beer and creating every kind of ruckus imaginable.  At which point the head wise guy shuts the door ominously, looks around the room, and says, “Now youse can’t leave.”

Immediately, as if on cue, a dozen or so club-wielding affiliate members poured out of the back room and exacted justice.

“Now youse can’t leave.” The movie, as good as it was, has been relegated to the attics of my mind, save for that one line. “Now youse can’t leave.” And so it is with some of my sake.

Backing gingerly back into the realm of sake-talk, we are often told “the rules” of sake care and such, but it is very important to remember that in the world of sake there are countless exceptions to every rule. One of those is the rule of drinking your sake young. Sure, it is true that almost all sake is meant to be consumed young, and that traditionally and historically it has always been done so (again, with some exceptions notwithstanding).

Of course, all this naturally leads to questions relating to how young is still young enough, or conversely stated, how old is too old? In actuality, there is no simple answer, which is why following the “younger is better, don’t mess around with aging sake at home” philosophy is best at first. But the ultimate truth is a bit higher than that.

The fact is that well matured sake can be very interesting, if you are into it, if you are open minded about what constitutes good, and if you have a sense of humor (for those inevitable mis-judgements).

There are several vaults for sake in my office, some cold, some not. Over the course of time, the nature of my work dictates that many a bottle finds its way to me. Try as I might (and oh, I do try), I cannot drink them all in a timely manner. So I often find myself peering into a three-level storage bin six bottles deep and as many wide, pondering what has to go next. And inevitably, I will find one or two that I feel should be tasted soon or they could potentially begin that long, slow, downhill slide.

But one of the great joys of this process is to find one or two that definitely should have been consumed a couple of months earlier. And if I think they can stand up to it, I look at ‘em and say with a forced sinister smile, “Now youse can’t leave.” And I deliberately lay them down for months or more, knowing full well the risk I am taking in doing so. Sometimes I am pleased with the results; other times I just tell myself that I am.

My point is decidedly not to suggest you indiscriminately leave your sake laying around. Rather, I simply want to point out that the world of aged sake does in fact exist. While it may be a small percentage of all sake made, and while few brewers make it, and even fewer apply an organized approach to producing it regularly, it can be a fascinating part of the sake world.

Aged sake is not unequivocally better, nor any more special, and in general only commands slightly higher prices. It is not really collectible and does not increase with value. And like most of us, it does not much resemble what it was in its youth. However, aged sake is in fact very interesting and worth checking out whenever you might come across it.

Tanks of sake awaiting perfect maturity

Should you come across an aged sake, by all means try it. Should you find one that has been forgotten, or one to which you did not get around to drinking after purchasing it years ago, do not despair! Lower your expectations, raise your sense of humor, and try it. You may be very pleased with the results, and if not, you have gained a useful education on how sake ages.

Such are the idiosyncrasies of the sometimes frustrating, often-times interesting, always one-step-ahead-of-human-intellect world of sake.
This kind of vagueness does not stop at aging sake; it keeps us all guessing at every step. After a certain period of time, after crossing a vague threshold of sake understanding, we become so interested in sake’s intricacies and exceptions that even if we wanted to stop studying it, we find we cannot.

This is the point in time when sake itself looks us all in the eye and says, “Now youse can’t leave.”
