Single malt Scotch refers to single malt whisky made in Scotland. To qualify for this category, a whisky must have been distilled at a single distillery using a pot still distillation process and made from a mash of malted barley. Therefore, a single malt means that the whisky has not been blended elsewhere with whisky from other distilleries. As with any Scotch whisky, a single malt Scotch must be distilled in Scotland and matured in oak casks in Scotland for at least three years, although most single malts are matured longer.

Single malt whisky is malt whisky from a single distillery.
