Whisky is an alcoholic beverage distilled from grains, often including malt, that has been aged in casks. The alcohol content of a whisky ranges from a legal minimum of 40%, and although it has no upper limit, the highest common content to be found is 63.5%.

"Whisky" is the name generally given to the drink in the United Kingdom (including Scotland), Canada and Japan, while the term used in the United States and Ireland is "whiskey".
