Vodka

Vodka is a clear distilled alcoholic beverage. Its varieties originated in Poland and Russia. Vodka is composed mainly of water and ethanol (alcohol), but sometimes with traces of impurities and flavourings. Traditionally, it is made by distilling liquid from fermented cereal grains and potatoes since the latter was introduced in Europe in the 18th century. Some modern brands use maize, sugar cane, fruit, honey, or maple sap as the base. Read more on Wikipedia
