Which is more important, rice or technique?

The answer: Yes.

The sake world is rife with paradox. There are so many aspects of sake that are this way, you are told, but a day later another authority says, no, it is not that way. And while you are still scratching your head to figure it all out, you discover things to support both sides of the story. And then, yet a completely different side appears too. Sure, there are principles and rules, but sometimes the exceptions to them outnumber the conforming instances.

One major enigmatic part of the sake world is rice, or more specifically, the importance of using proper, high quality sake rice rather than just regular sake rice – or even table rice – in making good sake. According to some folks, the choice of rice strain determines everything about a sake. Some brewers insist on using only one variety, or just a few.

Then there are those that say technique and brewing methods are more important than the choice of rice in determining the nature of imada yamadanishiki 70 / 35the completed sake. This concept is backed up by the fact that a dozen brewers can take the same rice, even milled to the same degree, and make a dozen completely different sake. How then could the rice really play that much of a leading role?

Rather than the folly of attempting to answer that – an exercise in futility of there ever was one – let me instead be part of the problem and actually support the paradox by showing an extreme example of each of these facets of the jewel that sake is. While this approach may not be so helpful in ultimately understanding sake, it may help encourage us to stop even trying, and just enjoy it.

So let us first look at this idea: to make the best sake, one needs to start with the best rice available. This would be easier to state if there was such a thing as “the” unequivocally best sake. But there ain’t. So let us lower our expectations just out of the gate and say that to make really good sake you have to start with really good sake rice.

Often but not always this means Yamada Nishiki. It has all the necessary qualifications in that it is easy to work with and easy for brewers to bend to their will. It behaves. Of course, it is not the only game in town, and there are brewers that do not use it at all. But a ridiculously high percentage of breweries use at least some Yamada Nishiki.

So Yamada is good. But there is good Yamada Nishiki, and there is great Yamada Nishiki. There is a ranking system, used predominantly in Hyogo Prefecture where the best Yamada grows. And there are microclimates and even particular rice fields in which the best Yamada Nishiki is harvested, measured by objective and measurable standards.

And make no mistake: when top-grade rice like that is in the hands of a good toji and crew, the resulting sake is something special, something beyond the norm. It is not really a matter of being sweeter, or dryer, or more balanced or more expressive or fuller. It’s much harder to nail down concretely, but the difference seems to be a matter of reverberation or resonance in the overall flavor profile. But it is immediately recognizable as something that is clearly a but above. One great example of this is Isojiman Junmai Daiginjo made with Yamada Nishiki from Tojo in Hyogo, but there are others. And this makes it clear that the best rice can lead to subtle qualities that appeal to almost everyone.

But then there’s the rest of the story…

There are also breweries that can make extremely enjoyable sake using less than stellar rice. Traditional techniques combined with modern measurement and technology help brewers tweak things to the point where they can maximize some things during production and minimize undesirables at the same time.

There is a brewery of which I am fond that is located in western Japan. It is quite popular and well distributed these days, and while the company is growing steadily, they are far from huge. I’ll hold back on naming it as the below might not be public information. The toji there is very regimented, and is not emotionally attached to traditional techniques, or at least not just because “that’s the way it’s always been done.” He uses plenty of machines, and eschews some steps that other toji consider indispensable.

After a recent visit to the kura, I was tasting through the lineup with the toji (master brewer) and the kuramoto (the owner of the company), and we were discussing their labeling as we did so. They do not hide the grade of each of their products, but do not put it on the front label either, relegating it to small characters on the back label. But each product has a unique name, like a sub-brand, that lets consumers associate an impression with it. So selecting and remembering their products are quite easy.

“Too much information, like grades and seimai-buai and all that, is distracting in our opinion. Sake should be judged on how it tastes and smells, and not much else. So we do not hide this information, but we deliberately downplay it,” they explained.

This attitude is slowly taking root, with more and more brewers releasing products with that kind of minimalist labeling. While there are admittedly few such product on the market right now, I expect it to grow to trend-like proportions over the next few years.

“Also, you’ll notice we do not put the name of the rice on the bottle either,” continued the kuramoto. “And that is deliberate too.”

“We brew almost all year-round here. And this product,” he said, hoisting a 1.8 liter bottle of their best-selling junmai ginjo, “is made from Yamada Nishiki. Basically. The thing is, we can’t always procure it for a full 12 months; there are years where there is not enough to go around. So once in a while, we have to use a different rice in a couple of batches.”

“So the truth is, I don’t know what rice is in there. There is an extremely high probability that it is Yamada, but I just don’t know for sure!” He exuded complete confidence in their way of doing things.

While the reasons and reality of that approach could go on forever, one things struck as quite significant. Their products are extremely enjoyable, and also extremely consistent. The toji has it dialed in: he knows just what to do with whatever rice he can get to make the final product taste just like that made with Yamada Nishiki. I am willing to bet he struggles more with the non-Yamada to get it to “behave” than he would like. But at the end of the day, he maintains great quality and stability while using “mostly Yamada, but not always.”

So yeah, great rice is important. Unless it isn’t.

In truth, this conversation could go on forever. It could easily wax philosophical. Some would argue that you need that top-grade rice to make top-grade sake, and even for exorbitant prices there is a market for it. And such sake is outstanding. But is it certainly is not the most fitting tipple for all occasions; no way. Glitter. Glam. Bling. And we all like glitter, glam and bling once in a while, this guy included.

Climate Change and its Effect on Sake Brewing

Warmer temperatures and strong storms are not to be trivialized!

The weather has been warmer the past few decades, and the environment has been much less stable overall. Japan is experiencing this as much as anywhere else, and while its effect on the sake world is not yet huge, everyone is aware of the changes and how they could impact things in the future. Sake production itself and, of course, rice growing are the two main things to consider.

Let’s look at production first. Of course, temperature is hugely important during sake production, as a difference of just a couple degrees during fermentation would lead to a completely different sake, in terms of both flavor and aroma. Basically, ginjo and daiginjo call for lower temperatures so as to stress out the yeast and extract all those fruity essences. Not that this kind of sake is the only game in town. But you know; I’m just sayin’.

But note, the industry pretty much has that covered. In the old days, sake brewing was much more at the mercy of nature. Kura (breweries) are built to be cold in the winter, and cooler than the outside in the summer. Thick earthen walls help that cause to some degree of course.

Jacketed tanksBut today, temperature control is much easier than in the past. Tanks can be concentrated into smaller space than in the past, and those rooms within the kura can be further insulated and cooled with modern climate control equipment, no problem. Individual tanks themselves can be chilled too, with all kind of tools now available such as jackets through which coolant can be run. Jury-rigged versions like garden hoses running chilled water can also be used for more budget-conscious breweries.

So proper, well thought-out industrial design can solve a lot of these problems. On top of that, there are also those breweries (like Taketsuru in Hiroshima) that take the philosophy that it is better to just let nature have her way, and let that be expressed in the year’s sake.

In truth, it’s not really this simple, since temperature control calls for more resources and energy. As time passes, we all need to be increasingly aware of that too as it can be part of the problem. The sake industry is not a large industry, and is just a drop in the bucket of energy consumption. But we still need to be conscious of such things.

Rice growing is another issue altogether. While changes are indeed apparent, thus far they are manageable rather than massive. But even bigger changes are afoot for sure.

For example, even though the climate has changed, the best Yamada Nishiki still comes from the same microclimates – such as Tojo and Yokawa – in Hyogo Prefecture, and the amount of top-quality rice that is harvested each year has not declined.

Surely modern technology in all areas helps this. For example, weather radar lenabled everyone to see the massive typhoon Hagibis that engulfed Japan in early October. This allowed the farmers growing Yamada Nishiki to quickly harvest the rice – albeit a bit earlier than they would normally have done it. An early harvest is much better than a ruined one. More significantly, though, climate change affects things in ways beyond higher temperatures.

There are other adaptations to the changing climate that are happening as well. For example, most good sake rice strains do not like colder temperatures, and so not much good sake rice has been grown in the northern parts of Japan. But as things warm up, the northernmost limit is getting nudged even further north.

Hokkaido, the northernmost of Japan’s four main islands, was long known for having not-so-good rice, to put it mildly. One brewer from there told me he found a company advertisement from the 80s that bragged – not stated but bragged – that all of their sake was made with rice grown on the main island of Japan, and not in Hokkaido!

But over the past decade or so, things have changed. There are several very good strains of sake rice being grown in Hokkaido, and the rice-growing industry there is actively marketing it to the rest of the country, and successfully so.

As an interesting anecdote related to this, Saga Prefecture is part of Japan’s southernmost of the four major islands, Kyushu. Plenty of good sake rice is grown there, including the aforementioned and sometimes overly adulated Yamada Nishiki. But one brewer I spoke to from Saga is going out of his way to buy and brew with rice from Hokkaido. Why would he bother with this when there is so much good rice locally available?

Yamada before harvestBecause he has his eye on the future. He feels that in time, good sake rice production may move further north. So he wants to get experience with the rice from that region and learn to make increasingly better sake with it. And, furthermore, he wants to open the channel of distribution and establish a relationship with the rice-producing industry up there, so that when Hokkaido rice gets more attention, he will enjoy the benefits of having developed a long-term, mutually beneficial relationship that will afford him preferential status.

Hopefully, we will all act in concert to slow down climate change and take better care of the planet. But the sake brewing industry is already pondering a handful of Plan B options. Let us see how it unfolds over time.

Blending in the Sake World

The brewing season – the first one of the new Reiwa era in Japan – has just begun. Most places have a tank or two, maybe more, already fermenting away. The fall is also the season for lots of tasting events of all kinds of groups and of various scales.

Indeed, the fall is the traditional season for announcing to the world how well the sake of the previous brewing period has turned out. But there is another tasting season, in April or so, where breweries will show their just-brewed sake, called “shinshu,” with all involved knowing it is a bit too young to completely enjoy. Worded more diplomatically, it is understood that most sake will get even better with a few months’ maturation. Such shinshu is brimming with potential, and can tell us a lot about how things went over the past winter.

Most of these are large tastings comprised of many brewers and a lineup of sake from each. But one in particular that I look forward to and value highly each year is put on by just one small brewer, for a couple of hours, in the dim, less-than-extravagant office of his main Tokyo distributor. The fact that I am extremely fond of this kura’s sake is surely a big part of my excitement.

The sake is called Hitakami, from Miyagi, and in short, what Hirai-san the owner does is to line up 30 or so sake, mostly pasteurized but some nama (unpasteurized), all genshu (undiluted, so perhaps a couple of percent higher in alcohol), and all very young. But what is unique here is the chance for those of us in the industry to taste each tank brewed with all its sparkling individuality. No homogenizing blending, not at that stage anyway. No chance for the sake to mellow out. And nothing to equal the playing field amongst them.

Bottles are lined up on a long, narrow table approachable on both sides, and flanked with spittoons strategically placed every meter or so. Each sake is labeled with the batch number of from whence it came. The handout received upon entering gives us the necessary information: “Batch #37, Junmai-shu, Hitomebore rice at 60%, Miyagi Yeast, Nama Genshu, Nihonshudo 5, Acidity, 1.5.” And so on down the line. Furthermore, we were given the date on which the sake was pressed, i.e. the day fermentation ended.

So each bottle at that tasting comes from a separate tank; none were blended. And this makes it extremely educational and interesting, as we can see how different tanks of sake brewed with the exact same ingredients and methods can be very, very different. And a tasting like this is the only time we can experience that. Why?

Because almost without exception, within a given brewery, each season all the sake of a particular grade that is destined to be sold as the same product will be blended together to ensure consistency. But they do not, for example, blend tank #33 and tank #54 since that combo would lead to something great, as they might do with some other alcoholic beverages. The intention is different.

Are there exceptions to this? Of course there are. There are exceptions to everything in the sake world. For example, there are some brewers that deliberately do not blend their products so as to let the uniqueness of each tank do the talking – the sake called Mana 1751 is one such example. And one large and historically very significant company, Kenbishi, does in fact identify three or more tanks in each year’s batch that will morph into something very special when blended. But most of the time, for almost all brewers, blending is done to promote uniformity across all the tanks destined to be sold as one particular product.

Consistency is an important expression of quality in the sake industry, both from bottle to bottle and from year to year. Ensuring that to the degree that it is possible is the objective of blending in the sake world.
