Single Grain

A detailed explanation of the whisky style built on grains other than malted barley. Typically corn, wheat, or other unmalted grains are used, and the distillation is often done in column distillation, which gives a more neutral and lighter body compared with malted barley.

Definition

Single grain refers to whisky produced at a single distillery from unmalted grain. In Scottish tradition, the term often describes a whisky produced using column distillation, which yields a cleaner and lighter spirit than traditional pot still whiskies.

Grain choice and distillation method

• Common grain types: corn, wheat, rye, and other unmalted grains.
• Distillation method: column distillation (column still/patent still), which allows higher alcohol strengths and a more neutral, light profile.

Production and maturation

• The aim is to create a mild, neutral base, often used as the foundation in blends.
• After distillation, the whisky is aged in oak casks, developing notes of vanilla, caramel, and light spiciness, depending on the cask and aging time.

Taste and use

• Flavor profile: generally fresh, with a light sweetness and a more subdued character than malted barley. Depending on the grain type and the cask, notes of corn, vanilla, and dried fruit may appear.
• Use: primarily as a base in blends, but some single grain examples are released from specific distilleries as single-grain products.

Notes on terminology in different regions

• In Scottish tradition, single grain refers to whisky produced at a single distillery from unmalted grain, often distilled in a column still, and matured in oak casks.
