What kind of barrels is The Glenlivet 18 aged in?
The Glenlivet 18 Year Old is matured for at least 18 years in first- and second-fill American oak casks and in ex-sherry casks. According to The Glenlivet, the American oak brings tropical fruit and the sherry casks bring spice.
How does The Glenlivet 18 differ from The Glenlivet 21?
Age aside, casks set them apart. The Glenlivet 18 Year Old draws on first- and second-fill American oak and ex-sherry casks, while The Glenlivet’s 21 Year Old, part of The Sample Room Collection, goes from traditional casks into a finish in first-fill oloroso sherry, Tronçais oak cognac and Colheita vintage port casks.
