Blair Athol's signature style comes from the use of water from the Allt Dour burn and its preference for sherry cask maturation, which imparts a deep, complex flavour profile to its whiskies. The distillery's production process, which includes traditional worm tub condensers, contributes to the rich, full-bodied character of its spirits. Blair Athol plays a significant role in the blends of its parent company, Diageo, while its single malts are highly prized for their balance of sweetness and spice, making them a must-try for whisky lovers.
