Scotch whisky is malt whisky or grain whisky, made in Scotland.

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.
