Scotch whisky (often referred to simply as "Scotch") is malt whisky or grain whisky made in Scotland. All Scotch whisky was originally made from malt barley, but commercial distilleries began introducing whisky made from grain and rye in the late eighteenth century.
Scotch whisky is divided into five distinct categories:
Single malt Scotch whisky
Scotch whisky produced from only water and malted barley at a single distillery by batch distillation in pot stills.
Single grain Scotch whisky
Scotch whisky distilled at a single distillery but, in addition to water and malted barley, may involve whole grains of other malted or unmalted cereals.
Blended malt Scotch whisky
a blend of two or more single malt Scotch whiskies from different distilleries.
Blended grain Scotch whisky
a blend of two or more single grain Scotch whiskies from different distilleries.
Blended Scotch whisky
a blend of one or more single malt Scotch whiskies with one or more single grain Scotch whisky
