Vodka, one of the world's most popular liquors, is composed solely of water and ethyl alcohol with possible traces of impurities and flavorings. Vodka is made from a fermented substance of either grain, rye, wheat, potatoes, or sugar beet molasses.
Vodka’s alcoholic content usually ranges between 35 to 50 percent by volume; the standard Russian, Lithuanian, and Polish vodkas are 40 percent alcohol by volume (80 proof).
Vodka is traditionally drunk neat in the vodka belt — Eastern Europe and the Nordic countries — and elsewhere. It is also commonly used in cocktails and mixed drinks, such as the bloody Mary, the screwdriver, the White Russian, the vodka tonic, and the vodka martini.
