One of my more exciting outings this year has been to the Annual Sake Tasting and Lecture led by John Gautner at the Japan Society in New York City. Eleven brewers came from Japan to show off 32 labels of the highest quality sake available. The Japan Society is one of my top five favorite places in NYC and has been for years. The space is gorgeous and the programs offered are worth checking out. Lots of theater, film, language classes and business/cooking/zen buddhist lectures. But this blog is not about the Japan Society! It's about Sake!!
The process of creating sake is similar to a mixture of wine & beer, with a few unique steps all its own. In beer there are the 3 M's... Milling, Malting and Mashing. In sake production, we have our seimaibuai or "milling" step. Malting does not exist to extract sugars from rice as it does with barley due to the lack of germination. In short, malting does not work for a grain such a rice, so sake brewers use a seemingly magical fungus, Aspergillus Oryzae to break down the dense carbohydrates. This fungus is more commonly known as "Kōji." Kōji, like yeasts in beer, impart most of the aromatic flavors in this special beverage. It gives sake the flavorful allure of banana bread, papaya, cucumber, honeydew, citrus and more. Kōji is also used in the production of Shōchū, which is a distilled spirit (made from barley or sweet potato) with a higher alcohol content than sake (around 25%) but with very similar aromatics. Kōji is what prepares sake rice for brewing by making them into fermentable sugars. Go Kōji!
Specific types of rice and water will determine the style and flavor which will result in the final product. The percentage of excess outer layers of sake rice milled away also determine how pure and flavorful it will be, and how many imperfections or impurities will exist. The levels are as follows:
Junmai Daiginjo/Daiginjo: 50% or less remaining rice. (Only 3% of all sake made)
Junmai Ginjo/Ginjo: 50-60% remaining rice. (Only 4% of all sake made)
Honjozo: 70% or less remaining rice.
Junmai: No milling requirement.
Futsu (“Table Sake”): Also no milling requirement. (74% of all sake made!) This is probably what your drinking served hot at your local Japanese restaurant.
Now that we know a bit about sake production, I can mention this very unusual heirloom rice varietal produced by Imada Sake Brewing Co. after more than 100 years of disappearance. The "Forgotten Fortune" refers to the heirloom varietal of sake rice called Hattanso. It is native to Hiroshima and discovered in 1875. This rice had an important impact on the original style and flavor of sake brewed in Hiroshima and gave the region their excellent reputation. Through Imada's kind revival, we can all enjoy this historic rice varietal and all it has to offer the sake world and its consumers!
This was an awesome time! If any of you are interested in really jumping into sake culture, subscribe to the first ever sake magazine published in English! It's called Sake Today and the 2nd issue is coming out soon! Or go visit Sakaya in the East Village, NYC. I intend on doing both very soon. Mata ne!
