It is believed that production of sake in Japan dates back to the third century BC. Today, sake is defined by the Japanese Government as an alcoholic beverage containing between 1 and 22% alcohol, produced using rice, rice koji and water, and has a production process involving the pressing/filtering of mash.
The national beverage of Japan, sake (pronounced “sah-KAY,” but usually called something more like “sockey” by Americans), is a fermented rice beverage — typically referred to as a rice wine — that has been enjoyed since at least the 8th century, though some historians believe it was consumed hundreds of years earlier.
