The Macallan 21 Years Old exemplifies classic Highland Single Malt, delivering an extraordinarily smooth, delicate, yet complex palate. Each cask influences its contents in different ways. Spanish oak casks, seasoned with sherry, impart a deep, rich colour with aromas and flavours of dried fruit, spice and chocolate orange. American oak casks, seasoned with bourbon or sherry, impart a subtle, delicate colour with hints of apple, floral, vanilla and sweet citrus aromas and flavours.
