Sake is an alcoholic drink made from fermented rice. Often referred to as nihonshu (日本酒) in Japanese (to differentiate it from "sake" which in Japanese can also refer to alcohol in general), the drink enjoys widespread popularity and is served at all types of restaurants and drinking establishments. And as interest in Japanese cuisine has grown internationally, sake has started to become a trendy and recognizable drink around the world.
The foundations of good sake are quality rice, clean water, koji mold and yeast.
