Glenglassaugh Evolution is created by maturing the whisky in a unique combination of the finest hand-picked ex-Tennessee first-fill whiskey barrels. This expression shows great depth of character and finesse, a harmonious combination of whisky and oak. Bottled at 50%, natural colour and non chill filtered, Evolution represents the heart of Glenglassaugh’s distinctive personality, and indeed the landscape in which it is set. Glenglassaugh has been producing whisky at their Sandend Bay distillery since 1875, with high quality ingredients and traditional distillation methods, to create expressions of the highest quality.
