Single Malt Whisky – One Distillery, One Grain
Definition
A whisky produced at a single distillery using only malted barley as its grain.
What It Means
“Single” refers to one distillery, not one cask or one batch. A bottle may contain whisky from many different barrels, but every drop comes from the same producer.
Because the whisky is made entirely from malted barley, the character of the distillery and its maturation process often shine through, making Single Malts popular with enthusiasts.
Common Characteristics
Often showcases the personality of the distillery, with production methods, cask selection and maturation playing a major role in the final character. Single Malts can range from delicate and elegant to rich, complex and bold.
Depending on the cask and production style, Single Malts can also be rich, smoky or heavily influenced by sherry, port or wine casks.

Single Malt tells you where the whisky was made and what grain was used, it doesn’t tell you how old it is or whether it’s better than another style.

What It Means
