Part of Glenmorangie?s Prestige Range, this 18 year old spent its first 15 years in American white oak bourbon casks. After this time, 30% was transferred to Oloroso sherry casks where it spent its final days, as the rest remained in bourbon casks. After 18 years has passed in total, the whisky was reunited and bottled at 43% ABV. A thick, creamy and fruity single malt presented in a wonderfully elegant bottle. It certainly looks prestigious.
