General Flashcards
What is Saké?
Saké is a unique fermented beverage made from rice, water, yeast and kōji-kin.
What is aspergillus oryzae?
Also known as kōji-kin, aspergillus oryzae is a mold that converts the starch in rice into fermentable sugar in a process known as saccharification.
What is saccharification?
The process of creating sugar molecules from starch molecules.
What is heikō fukuhakkōshiki?
Heikō fukuhakkōshiki is also known as multiple parallel fermentation, the unique process in which saké is made.
What is multiple parallel fermentation?
The unique process for saké making in which saccharification and fermentation take place simultaneously.
What is seimai?
The process of milling or polishing rice for saké production.
How is rice for saké different than normal table rice?
Good sake rice contains a higher percent of starch in its center and most of the fat, proteins and minerals closer to the outside of the grain.
What is Senmai?
After polishing to the desired degree, rice is washed (senmai) to remove the nuka left clinging to the grains from the polishing process.
What is nuka?
The rice powder created from the seimai or polishing process.
Used in livestock feed, many foods as well as distilled for use in low-cost alcoholic beverages.
What is the seimaibuai?
The “percent of the remaining grain size” or degree to which the rice has been polished.
What is a seimaki?
A modern saké polishing machine.
What is shinseki?
The process of soaking the rice after milling in order to prepare the grains for steaming.
What is a koshiki?
The vat in which rice is steamed in the large quantities needed for saké production.
What is mushimai or jōmai?
The process of steaming the saké rice after it has been soaked and before kōji production can begin.
What is seikiku or Kōji-zukuri?
The process of making kōji.
Steamed rice is combined with kōji mold or kōji-kin and cultivated for 40-60 hours (usually about 2 days) to promote saccharification.
What is the room designated for kōji production in a saké kura (brewery) known as?
Kōji muro.
What is the Japanese word for saké? What does the word saké mean?
The Japanese word for saké is nihonshu- the alcohol of Japan.
(Nihon - Japan, shu - alcohol)
Saké literally translates to alcohol and can mean beer, wine, whiskey or actual “saké”.
When is a typical rice harvest?
September.
Traditionally saké brewing takes place over the winter and the same workers fish in the summer.
(Similar to wine.)
When is saké traditionally brewed?
Saké is traditionally brewed over the winter- the cooler temperatures are conducive to a cleaner ferment. Most breweries are open from October to March.
Does saké need to be made from fresh rice?
Saké can be made from rice of any age- it is made from dry rice and is soaked at the beginning of the saké making process.
What is the shinpaku?
The pure starch “heart” of a rice grain- what saké is ideally made from.
What is the purpose of lactic acid in saké making?
Lactic acid is used the same way as sulphur is in wine making- to kill any wild yeast or bacteria before the brewer inoculates with their preferred yeast strain.
Does saké contain sulfur like wine?
Sulfur is not needed in saké making- lactic acid is used in its place during the saké making process and then saké is pasteurized- often twice.
How long does the traditional kōji making process take?
40-45 hours. The kōji is rotated every hour for roughly two full days- often by the same individual.
What is the typical alcohol content of a finished saké? (Before water is added)
20-22%ABV
What is muroka?
A style of saké that is truly unfiltered- but clear. The yeast and rice are allowed to settle to the bottom and the saké is “scooped” off the top, resulting in a rich style of Saké.
How long does a typical batch of saké take to brew?
30 days is the minimum for high quality saké but sometimes up to 45-60 days.
