This whiskey is fruity, thick, creamy and comes in an attractive and elegant bottle. The Glenmorangie 18 Year Old single malt Scotch whiskey spends fifteen years maturing in American white oak bourbon casks. About 30% is matured for three years in Spanish Oloroso sherry casks. When both have reached 18 years, they are blended back together and this produces a full whiskey with a rich bouquet and rounded flavour. The Oloroso sherry casks provide a degree of vibrancy and the raisin-like sweetness of the sherry is toned down by the nuttiness of the American oak.
