Sake, saké (Japanese: 酒, Hepburn: sake; SAH-kee, SAK-ay), or saki, also referred to as Japanese rice wine, is an alcoholic beverage of Japanese origin made by fermenting rice that has been polished to remove the bran. Despite the name Japanese rice wine, sake, and indeed any East Asian rice wine (such as huangjiu and cheongju), is produced by a brewing process more akin to that of beer, where starch is converted into sugars that ferment into alcohol, whereas in wine, alcohol is produced by fermenting sugar that is naturally present in fruit, typically grapes. This process is called Multiple Parallel Fermentation.
Although similar, the brewing process for sake differs from the process for beer, in which the conversion from starch to sugar and then from sugar to alcohol occurs in two distinct steps. Like other rice wines, these conversions occur simultaneously when brewing sake. The typical alcohol content also differs between sake, wine, and beer; while most beer contains 3–9% ABV and wine generally contains 9–16% ABV, undiluted sake contains 18–20% ABV (although this is typically lowered somewhat by diluting with water prior to bottling).
