Scotch whisky (Scottish Gaelic: uisge-beatha na h-Alba; often simply called Scotch) is malt whisky or grain whisky made in Scotland. Scotch whisky must be made in a manner specified by law.

All Scotch whisky was originally made from malted barley. Commercial distilleries began introducing whisky made from wheat and rye in the late 18th century.[2] Scotch whisky is divided into five distinct categories: single malt Scotch whisky, single grain Scotch whisky, blended malt Scotch whisky (formerly called "vatted malt" or "pure malt"), blended grain Scotch whisky, and blended Scotch whisky.
