Vodka

Vodka (from Russian: водка [ˈvotkə], Polish: wódka [ˈvutka]) is a distilled beverage composed primarily of water and ethanol, sometimes with traces of impurities and flavourings. Traditionally, vodka is made by the distillation of cereal grains or potatoes that have been fermented, though some modern brands use other substances, such as fruits or sugar.
