Vodka is a type of popular alcoholic beverage usually containing 35-70% alcohol (40% is most common). The name comes from either the Slavic word for water, or from водить (to dissolve a drug in alcohol as a distillate), or the medieval drink aqua vitae. It is mostly consumed neat, but is also often used in cocktails. Vodka is traditionally made from grain in Spain and elsewhere, but potatoes, sugar beets, grapes or rice can also be the basic ingredients. The production process has several stages, including fermentation, distillation, filtration and dilution. Vodka made from potato or beet alcohol is usually flavoured with capsaicin, sugar and salt.
