Ch.1 – What is Sake? Flashcards
What are the effects of global warming to Yamada Nishiki cultivation?
- The ripening period has become early (Yamada Nishiki is a slow growing rice that ripens late and is best suited for regions that have a long autumn)
- Ripening period falls in the high temperature months and the grains do not fill sufficiently
In the sake making, what is the fermenting mixture of rice (steamed rice), rice-koji and water ?
Moromi (main mash 醪)
During the Taisho period, the main stream sake was dry sake with high acidity. State the possible reasons
- proliferation of lactic acid in the moromi
- the rice polishing ratio was at most 90% which caused the yeast become overly active=>the amount of acid in the moromi increased
- When the rice-polishing ratio is high, the steamed rice is not readily soluable=>the moromi ended up dry with little sugar
In what year the Food Agency categorized Hyogo into two districts (A and B) according to regional differences?
1951 (the following year the districts were changed into three categories A, B and C)

In what year the Hyogo Brewing Rice Special District Promotion Association changed the existing “A-Districts” to “Toku-A-Districts”?
1964
(Toku-A-Districts were further divided into Toku A-a, Toku A-b and Toku A-c Districts)
From then on, Yamada Nishiki was no longer cultivated in B and C-ranking districts.
Explain Mura-mai seido (village-rice system 村米制度)

What triggered the expansion of cultivation of Yamada Nishiki by Hyogo breweries after the World War II?
In 1940, Enforcement of temporary rice-rationing regulative forced the breweries to use locally produced rice.
Up till then, they considered “Chugami-mai” mainly cultivated in Ibaraka, Osaka to be the best rice for making rice and were reluctant to try new varieties. This led to research on making koji with Hyogo produced rice including Yamada Nishiki
How was Miyamizu of Nada discovered?
A sake brewer Tazaemon Yamamura compared sake made from his Uozaki (Kobe City) and Nishinomiya (Nishinomiya City) and found that the sake made from Nishinomiya had superior quality

What makes Miyamizu suited for sake making?
Miyamizu is rich in phosphorous, potassium, and chorine.
These three minerals are vital compounds that promote the fermentation of the yeast. The minerals play an important role during the initial stages of the fermentation process.
