Single Malt Scotch is whisky made in Scotland using a pot still
distillation process at a single distillery, with malted barley
as the only grain ingredient. 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). - "Malt" indicates that the whisky is
distilled from a single "malted" grain. Several types of grains
can be malted (for example, barley, rye and wheat are all grains
which can be malted); however, in the case of single malt
Scotch, barley is always the (only) grain used. - "Single"
indicates that all the malts in the bottle come from a single
distillery. Multi-distillery malts are usually called "blended
malt", "vatted malt" or "pure malt".
