The Macallan 15 Years Old Double Cask is a Speyside single malt matured in a combination of sherry-seasoned American oak and sherry-seasoned European oak casks. The American oak adds sweetness and vanilla, while the European oak brings richness and spice. Expect honeyed butterscotch, dried fruit, ginger and toffee, with a smooth, well-balanced finish that suits slow sipping neat or with a drop of water.
