Where does it come from ?
Japanese sake, which is made from rice as its raw material, cannot be produced without "rice." The culture of rice farming was introduced to Japan during the Yayoi period from the 4th century BC to the 3rd century AD. This is where the origin of Japanese sake lies.
In addition, there is "koji," which produces sugar from rice. This useful microorganism naturally occurs in Japan's humid climate and is not only used in sake brewing but also in various traditional Japanese food making, becoming an indispensable part of the Japanese diet.
What is sake made from ?
Sake is made from a combination of rice, water, yeast, and koji. The type of rice used to make sake is called "shuzo kotekimai" or saka-mai, which is a special type of rice that has larger, starchier grains than regular table rice.
The water used for making sake is also essential, and some sake breweries are located in areas with high-quality water sources.
Koji is a type of mold that is used to break down the rice starch into sugar, which is then fermented by yeast to produce alcohol. The combination of these ingredients and the brewing process results in the unique flavor profile and aroma of sake.
