Despite making the world’s best-selling single malt from its distillery that produces 21 million liters of pure alcohol a year, Glenfiddich still innovates around its signature Glenfiddich 12 year old. After past experiments with toasted oak, peated, and American oak casks, this vibrant amontillado cask finish from malt master Brian Kinsman adds sweetness and depth to the 12 year old, to deliver shifting tones of orchard fruit, rich oak, dried fruit, and enduring spices. —Jonny McCormick
