Single malt Scotch is single malt whisky made in Scotland. To be a single malt whisky, the whisky must have been distilled at a single distillery using a pot still distillation process, from a mash of malted grain. In Scotland, the only grain allowed to be used in a single malt whisky is barley. 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. (Most single malts are matured longer.)
