Beer or Wine

Wine is produced by fermenting sugars from fruits into alcohol.
Beer, on the other hand, is made by converting starch into sugar first and into alcohol thereafter.

Unlike beer, sake has alcohol content above 15%.

Hot or Cold

High grade sake is usually served cold in order to preserve aromas.
