Learning more about sake at Izumi (OSWSC)
Education, truly learning something new, is one of life’s greatest pleasures. Thus, I found myself greatly enjoying another evening sip-n-learn session at the Ontario Springwater Sake Company (OSWSC, also known as Izumi, the brand name for their sake). The topic this time was Tasting Sake.
On a bit of a sad note, I learned today that Takahashi-san, their toji or brewmaster, will not be staying too long in Toronto. Her husband and family are still over in Japan!
Today, it was Greg (one of the apprentice brewers) and Kaz Hayashi (the general manager) who ran the session.
The first thing we tried was the moromi from one of the mature tanks. Compared to the one fromb last week, this one was noticeably stronger, a little bitter, with no riciness but very noticeable alcohol. The bitterness is, apparently, characteristic of sake that’s ready to be pressed. This tank in particular will be pressed tomorrow, and has been fermenting for the past 23 days.
The next sake we tried was Teion Sakura. It’s a little different than I remember it, but still quite enjoyable. It was lightly fruity, with some acidity, and a very forward personality. It was bold and brash like a teenager, but still smooth and refined – clearly a teenager girl from a good school, to continue the analogy.
Next in line was a shiboritate, or fresh-pressed sake. In fact, this one had only been pressed 2 days ago. It had subtle fruitiness without the sourness or forward personality of Teion Sakura. A bit of dryness or astringency but still very smooth and refined. It was, however, lacking the mushroom aroma and cheesy flavor that the shiboritate I tried before summer this year had exhibited. I was a little disappointed, but since the shiboritate can be from any desired sake, I should expect it to be different each time.
Next was Nama-Cho filtered, and served warm. It was savory, well rounded, and very nice.
Warm sake is not for low quality sake, though that is a common belief. The warmth actually accentuates everything, including all the negative characteristics. However, a high quality, well-balance sake will be great chilled or warm, whichever suits the weather and the food best. However, this is best with pasteurized or filtered sake where the freshness isn’t the focus the way it would be with a good unpasteurized and unfiltered sake.
However, to show us the difference, we then tried an unfiltered Nama-Cho also served warm. It was a totally different beast! The flavor was much bolder, still very well rounded, but just very unmistakably full flavored.
Filtering removes particles of rice and yeast and decreases flavor. Pasteurization removes even more fresh flavors. Most in-store sakes are double-pasteurized, losing twice the fresh flavor. Nama-Cho, designed for wide distribution through stores, is single pasteurized. The unfiltered version that we tried still contained particles that impart extra and more complex flavors.
Each sake very different, based just on the koji and fermentation. The exact same ingredients are used for each sake that the OSWSC makes. It is what they do with it all that makes each sake so different from one another. Filtering after the koji, fermentation and pressing makes a huge difference, as we experienced with the warm Nama-Cho.
All of the sake at OSWSC are junmai – meaning no brewer’s alcohol is artificially added at any point. Alcohol is added to low-quality sakes to make things easier on the maker – you don’t have to control the fermentation as skilfully because you can crank it up with warmer temperatures and then kill the fermentation by adding enough alcohol to the mixture. Alcohol is also added to some high-quality sakes as well to enhance the aroma by acting as an evaporative vector for the scent molecules, much like the alcohol in fragrances that you spray or dab on yourself.
So how does one enjoy the bouquet of sake? First, smell without swirling. Then sip, breathe in gently and quietly from mouth, and breathe out through nose. That is how to enjoy the bouquet.
There was no theory part of today’s sip-n-learn, but it was definitely a round of experiential learning. I am left with the conclusion that we are lucky to have local sake brewery. Unfiltered, unpasteurized sake has more flavor, and you can’t get them from regular distribution chains. The uncontrolled conditions inherent in many of today’s beverage and packaged food supply chains means that you can only ship pasteurized, filtered sake. Without “cold chain” logistics, you couldn’t be sure otherwise that the sake would be good and remain the way you intended it to be. That is why we get much flatter flavor profiles from store-bought sake.
If I could get a taste experience like the unfiltered Nama-Cho via regular store-bought sake, that would be fantastic. However, I can’t and heading down to the visit the folks at the OSWSC in the Distillery District isn’t really much of a chore. I can live with having to go a little out of my way for fresh, superbly crafted sake!
