Vodka (Polish: wódka [ˈvutka], Russian: водка [ˈvotkə], Swedish: vodka [vɔdkɑː]) is a clear distilled alcoholic beverage with different varieties originating in Poland, Russia and Sweden. It is composed primarily of water and ethanol, but sometimes with traces of impurities and flavorings. Traditionally it is made by distilling the liquid from cereal grains that have been fermented, with potatoes arising as a substitute in more recent times, and some modern brands using fruits as the base.
Since the 1890s, standard vodkas have been 40% alcohol by volume (ABV) (80 U.S. proof). The European Union has established a minimum alcohol content of 37.5% for vodka. Vodka in the United States must have a minimum alcohol content of 40%.
Vodka is traditionally drunk "neat" (not mixed with water, ice, or other mixers), although it is often served freezer chilled in the vodka belt of Belarus, Estonia, Finland, Iceland, Lithuania, Latvia, Norway, Poland, Russia, Sweden, and Ukraine. It is also used in cocktails and mixed drinks, such as the vodka martini, Cosmopolitan, vodka tonic, screwdriver, greyhound, Black or White Russian, Moscow mule, Bloody Mary, and Caesar.
