Glenmorangie 18 Year offers rich marmalade flavors, honey and fig, with touches of caramelized orange and far-off campfire smoke. After 15 years of maturation in American white-oak, ex-bourbon casks, around 30% of the whisky is transferred into Spanish Oloroso sherry casks for three years. When both parts have reached 18 years, they are blended together. The Oloroso casks provide an incredible degree of vibrancy, while the American oak balances the raisin-like sweetness of the sherry. Enjoy neat, with a little water or 2-3 large rocks of ice.
