A Single Malt Whisky is made entirely at one distillery, from single “malted” barley as the only grain ingredient.
Blended Malt or Vatted Malt
A combination of single malts from various distilleries is called a Vatted Malt or Blended Malt. A Vatted Malt contains a number of malt whiskies that have been skillfully blended together to create a consistent whisky with its own distinct and identifiable character.
Usually made from corn, maize, or other grains rather than malted barley. It is distilled in continuous distillation process stills known as Coffey stills (apparatus used in distillation) instead of the pot still used for single malt whisky.
Blended Scotch Whisky
A blend of single malt whiskies and grain whiskies. A blended scotch whisky may contain a combination of whiskies from over 40 or 50 different malt and grain distilleries. The normal ratio of malt to grain is 60% grain and 40% malt. The percentage of malt used determines the smoothness of taste and texture.
