Unlike some heavier and more robust Single Malts, Glen Grant is crisp, clear, fresh and light. What really distinguishes it from other malts is the unique distillation process. As a first step they use incredibly tall stills, which help ensure only the lightest spirit becomes Glen Grant.
Secondly, they are the only distillery to use purifiers in both of their distillations. This was an invention of James “The Major” Grant which they still use to this day. This ensures only purest vapour is allowed to pass from the still to the condenser and therefore creates a fresh, and light whisky.
