Matured first in bourbon barrels then Oloroso casks, there's no finer example of a sherry cask finish than our 15 Year Old. It's the final three years spent in Oloroso sherry casks that gives Bowmore 15 Year Old the rich, deep colour and robust warming finish. Taste: Wonderful cedar wood and rich treacle toffee flavours. Spicy, toffee, sherry and barley. Appearance: Burnt Sienna. Aroma: Dark chocolate and raisin aromas compliment the classic Bowmore smokiness.
