Kirkland Signature 15 Year Highland Single Malt Scotch Whisky is a sherry cask-finished single malt scotch from the Highland region of Scotland. Bottled exclusively for Costco by Alexander Murray & Co, this whisky is aged for 15 years and bottled at 46.0% ABV.

The whisky features a rich, sherry-forward profile with notes of golden raisins, dried cherries, and marzipan. The nose is slightly boozy with cherry liqueur and coffee grounds from a lighter roast. On the palate, the sherry influence is prominent with golden raisins as the main note, complemented by dark cherries and marzipan that emerge after letting it rest on the tongue. The finish is relatively short with lingering hints of sherry and marzipan.

This Highland single malt offers pleasant, approachable flavors with more complexity than a typical sherry bomb, though some reviewers note it can be a bit weak on the palate. The whisky benefits from a splash of water or an ice cube to open up the flavors and reduce the heat. At its price point, it delivers excellent value for a 15-year-old single malt scotch, making it a solid choice for both neat sipping and premium scotch cocktails like a Rob Roy or Blood and Sand.
