Black koji mold (koji) mail order｜Amazake specialty store Ren MURO Muro [official mail order]
Black koji mold is a koji mold that has long been used in the brewing of awamori in Okinawa. As the name suggests, it is black.
While most amazake from Honshu uses yellow koji mold, black amazake is made by fermenting rice with black koji mold.
Since it contains a large amount of citric acid, it can keep the mash (moromi) relatively strong acidity, which prevents rancidity and prevents the growth of bacteria during fermentation, making it an alcoholic beverage in areas with relatively high temperatures. Suitable for brewing.
Amazake made with black koji mold has a sour taste, and it is very delicious when you drink it chilled from early summer to autumn.
