The Glenlivet - Triple Cask Matured, Rare Cask is originally a Travel Retail Exclusive. It’s a fruity expression that has matured in 3 different types of cask, with the majority of the whisky having spent its years in first-fill sherry casks. The whisky is bottled in small batches, although small is definitively relative here, as The Glenlivet is the second largest Scotch single malt brand in the world. Founded in 1824, Glenlivet has set the standard for Scotch Whisky for almost two centuries.
