Highland Park is known in using sherry casks throughout their core expressions for the entire aging process, not just a finish. Whereas the 12 and 18 year whiskies use mainly Spanish oak, the Highland Park 15 uses American oak (though not American sherry, thankfully). Not content with one cask alteration, the 15 is aged in 30% first fill sherry casks and 70% refill. While not in the same class of exclusivity as Highland Park’s Valhalla Collection, it is a little more elusive than the celebrated 12 year expression.
