Man this is a potent whiskey. Bottled at 63.9% ABV, this selection oddly tastes hotter than some slightly higher proof offerings I've tried from Highland Park. ( Westray, for example is bottled at 65.1% ABV ) The front of the taste is very sweet. Its hard to tell that this was aged in sherry seasoned casks because I don't taste the powerful influence of berries or red fruits like I normally would in a sherry cask whiskey. At this proof, the whiskey creates an interesting tingling sensation on my tongue. Not unpleasant but unexpected indeed. Toward mid mouth and all the way through, the sweetness gives way to a sensational hit of peat smoke. This whiskey finishes hot, with a stinging bite and high proof warmth. I get that cask strength selections are intended to be sampled with varying amounts of water drops. However, much to my downfall I cannot bring myself to introduce water or ice to any whiskey in the Highland Park catalogue. Still, for such a high proof offering; this whiskey still sings with the complexity I did not expect to find at this ABV. Even though this might be one of my least favorite Highland Park offerings, it is still significantly better than a lot of competing cask strength whiskies in this price point.
