Whisky or whiskey is a type of distilled alcoholic beverage made from fermented grain mash. Various grains (which may be malted) are used for different varieties, including barley, corn, rye, and wheat. Whisky is typically aged in wooden casks, which are often old sherry casks or may also be made of charred white oak. Whisky is a strictly regulated spirit worldwide with many classes and types. The typical unifying characteristics of the different classes and types are the fermentation of grains, distillation, and ageing in wooden barrels. == Etymology == The word whisky (or whiskey) is an anglicisation of the Classical Gaelic word uisce (or uisge) meaning "water" (now written as uisce in Modern Irish, and uisge in Scottish Gaelic). This Gaelic word shares its ultimate origins with Germanic water and Slavic voda of the same meaning. Distilled alcohol was known in Latin as aqua vitae ("water of life"). This was translated into Old Irish as uisce beatha, which became uisce beatha in Irish and uisge beatha [ˈɯʃkʲə ˈbɛhə] in Scottish Gaelic. Early forms of the word in English included uskebeaghe (1581), usquebaugh (1610), usquebath (1621), and usquebae (1715).
