This is a single malt Scotch whisky selected as a single cask bottling, with 17 years of maturation and a natural cask-strength style at 51.1% ABV. That combination often means a more individual character than large-batch releases, with fuller texture and more intensity in the glass.
Glen Garioch is known as a Highland distillery, and refill barrel maturation generally suggests the oak has supported the spirit without overwhelming it. For a novice drinker, expect a whisky where the distillery character is likely to remain clear, and consider adding a little water to explore how the aromas and texture open up.
