This fourth release of cask strength Highland Park has been matured predominantly in first-fill sherry seasoned European oak casks and American oak casks, along with a small quantity of refill casks, ex-bourbon casks and - for the first time - ex-port casks too.  Bottled straight from the cask, without the addition of water to reduce alcohol content, this Cask Strength series marries the traditional craft of whisky making with a modern approach to flavour exploration.
