October 1 is Sake Day! But…why?

Happy “Nihonshu no Hi,” or Sake Day!

October 1 of each year is officially designated “Nihonshu no Hi,” or “Sake Day.”

But why October 1? Why not April 1? Or May 20, or any one of 364 other valid days?

There are, not surprisingly, several reasons. However, the biggest reason is related to the written character for sake.Long ago, it consisted of only the right half of its current form; in other words, the original form of the character for sake did not include the three short lines on the left side, which, by the way, represent water, or at least liquid.

Rather, the original character for sake consisted only of the part that was made to look like a jar, indicating something holding liquid, which was of course an alcoholic beverage o

f some sort in the mind of those looking at the character.

Enter the Chinese zodiac: 12 animal signs that are traditionally used to number years in the traditionally accepted sequence. Long ago, by the way, it also was used to count two-hour periods in each 24-hour day.

The tenth of these is tori, or chicken (or perhaps rooster or cock). However, the written character assigned to each of these animals as used in the zodiac is not the standard characters used when referring to the animals in normal writing, but rather a special character and reading used only in these traditional Chinese zodiacal instances.

Also, one reading of this character is “toh,” which is a synonym for ten, a point that is of course tied in to the association of this particular character to the tenth hour, month and year in a cycle.

As with everything in the culture of sake, it is hardly random, yet hardly obvious. Therein lies its appeal.So, by fortuitous coincidence, the tenth year, hour and month, i.e. October are represented in the ancient Chinese zodiac system, also embraced by Japan, by the old character for sake. And, coincidentally, sake brewing begins in the fall, usually in October. And that is why the first day of the tenth month, October 1, is known as “Nihonshu no Hi,” or “Sake Day,” in Japan.

Traditional Fall Sake: Aki Agari and Hiya-Oroshi

2013 Sake Professional Course in Texas

Finally things are beginning to cool down as we move through nature’s most endearing season. Along with the rapidly turning leaves, cooler breezes, and better food, autumn is the traditional time when sake brewed the previous season goes on sale. Two types of sake you may come across in your autumnal perusing are aki-agari and hiya-oroshi.

Although sake is not usually aged for long, it is in general a bit too young to drink when the brewing season wraps up in the spring. Both the flavors and the fragrances are brash and sharp-edged, and a bit of time sitting quietly helps round out and deepen the sake.

Traditionally this was just about six months, and so the fall became the time when properly aged sake was released. Naturally, brewers often had to release some sake earlier to satisfy demand. But the connoisseurs knew that properly matured sake was well worth the wait. Sake released in the fall after the proper maturation period came to be known as aki-agari.

The only problem is that the term does not apply too well to modern times.

Fall still remains the traditional time for releasing sake, and this is the season with industry tastings galore. But in actuality maturation periods are far from uniform. Along with the advent of refrigeration came massive flexibility in terms of maturing sake.

These days, some brewers still only mature their sake six months or so, but others do so for a year or longer, and many at very low temperatures, to get just the profile they are looking for. Temperature affects the speed of changes during maturation, as does the choice of aging vessel (bottles or tanks). This allows brewers to tweak their flavor profiles, and maintain consistency throughout the year. But everyone does it a bit differently, and it makes the term aki-agari a tad less applicable.

Today, aki-agari refers in a broad sense to sake from the most recent batch released in the fall. You may see it at sake shops and department stores all across Japan.

Then, there is hiya-oroshi. The word hiya-oroshi has its origins back in the Edo period. Back then, finished sake was stored in the large cedar tanks used for brewing. Normally, this sake had been pasteurized once (by heating it for a short time) before being put in these tanks for maturation. If they needed to ship some out, they would have to pasteurize the sake a second time before putting it into small cedar casks – called taru – for delivery.

This is because the outdoor temperature was still high in the summer, which  would allow the sake to become warm enough where dormant enzymes could become activated, potentially sending the sake awry. A second pasteurization permanently deactivates these enzymes, removing that fear, but taking a bit of the zing of the sake along with it.

However, once it became cool enough in autumn, brewers could fill their taru from the storage tank without pasteurizing the sake, and ship it with no fear of it going bad. The lower temperatures of autumn ensured enzymes would not be activated. Such sake – sold in the fall without pasteurizing a second time before shipping – came to be known as hiya-oroshi.

Hiya-oroshi often has a bit more of a fresh, lively taste to it than other sake. While not as brash as freshly pressed sake, there can be a slightly youthful edge to it. Naturally, this varies greatly from sake to sake, and from kura to kura.

And, interestingly, some prefectures in Japan, most notably Nagano and Sago (although there are others) have set an official day for releasing hiya-oroshi, September 9. Naturally, this is not law, but just something the brewers have mutually agreed upon to add a bit of specialness to the event and the sake that it highlights.

What all this means is that now – right now – is the best time to try hiya-oroshi, and notes its slightly youthful touch, and the attendant appeal.

Yeasts that don’t foam up? Huh?

Non-foaming Yeasts

Admittedly, the subject of yeast types begins to push the envelope of geekdom. While some want to know both in theory and practice the difference between a Number 9 and a Number 10, and perhaps even between a CEL-24 and EK-1, most of us are content to sip and smile. Even so, there are some interesting historical, cultural and technical anecdotes surrounding even things as dryly scientific as yeast, and the topic of foamless yeasts, or “awanashi kobo,” is one such example.

First of all, just what is foamless yeast? Usually, when sake undergoes its 20- to 40-day fermentation, the foam rises in great swaths and falls again, especially over the first third or so of this period. In fact, brewers of olde would judge the stage, progress and condition of a given batch by the appearance (and smell, and taste, and even sound) of this foam atop the fermenting mash. Also, there are ten times more yeast cells in the foam than the mash itself, so very often yeast for subsequent batches is removed from the foam of healthy, vibrantly fermenting tanks.

So foamless yeasts, obviously, are strains of yeast that do create as much foam (there still is a little bit) as they convert sugars to alcohol, carbon dioxide, and more. The question is, why would anyone want to use them?

There are, actually, a number of very good reasons. Most of these are centered around efficiency, sanitation, labor-savings, and even safety. For instance, since the foam rises so high during fermentation, brewers cannot fill a tank to the brim with rice, koji and water since it would soon overflow with foam, leading to hygienic nightmare. Rather, they can only fill the tank initially about 3/4 of the way to leave room for the foam to rise and fall. Naturally, this puts a damper on one’s yields and efficiency. There may be 30 tanks in a fermentation room, but if you can only fill each up 3/4 of the way, your monthly yields are only 75 percent of what they might be. With foamless yeasts, however, this concern is all but a non-issue, and a brewery can get the higher yields out of each batch and tank.
Also, when foam does rise and fall, the remains that cling to the side of the tank are a veritable hotbed of bacterial activity, an orgy of undesirable microorganisms just hankerin’ to drop back in and do damage to the unsuspecting ambrosia-in-waiting below. So this must be assiduously cleaned off by the brewers. Not only is this hard and time consuming work, it is also quite dangerous, since it generally requires leaning into the tank. Falls into tanks are almost always fatal since there is no oxygen and the huge amount of carbon dioxide billowing up from the mash is harshly engulfing. So by eliminating the foamy remains, time, labor, and risk are spared. Finally, without all that gunk in the way, the hard-working yeast cells move and work a bit more freely, so that fermentation proceeds a smidgeon faster and can finish a day or two earlier.

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

The foamless yeasts that are commonly encountered out there today are non-foaming versions of the “usual suspects,” rather than being new, unknown, or total mutant life-forms.

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

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

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

Are these foamless yeasts really the same as their bubbling counterparts, except for the foam? Most brewers say, “Yes, the results are essentially same, and the practical advantages make it a clear choice for us.” However, there are a still a few hardcore toji who insist that the foamless manifestations are not quite as good as the foaming yeasts. Naturally, the ability to gather information from the appearance of the foam is eliminated. Still, most brewers feel that with foamless yeasts they get the same quality of sake, with less mess.

Foamless yeasts, at least those distributed by the Brewing Society of Japan, are designated by a -01 after the normal nomenclature. So a foamless Number 7 is known as 701, foamless Number 9 as 901, and so on. Those you are most likely to come across these days are 701, 901, and 1801.

Brewers are not obligated to provide information on the choice of yeast used, but often do. While there are countless yeasts used in sake today, just a few are non-foaming, and now you can recognize them.
