Cadenhead's Glenlivet is a single malt Scotch whisky presented at cask strength and drawn from a single cask. An 18-year-old age statement indicates lengthy maturation, while the high ABV suggests a concentrated style that may benefit from a little water in the glass.
For a novice drinker, this is likely to feel fuller and more intense than standard bottlings. Single-cask releases are often valued because they show an individual cask's character rather than a profile shaped for consistency across many casks.
