Kirkland Signature Islay Single Malt Scotch Whisky is a heavily peated single malt from the renowned Islay region of Scotland, bottled exclusively for Costco by Alexander Murray & Co. This non-age statement expression is bottled at 100 proof (50% ABV), delivering an authentic Islay character at exceptional value.

The whisky presents a golden color with intense peat smoke aromas balanced by sweet vanilla, citrus marmalade, and maritime brine notes. On the palate, it offers a full-bodied, viscous experience with layers of smoked vanilla, salted caramel, dark chocolate-covered cherries, ginger, and tobacco leaf. The finish is long and warming, featuring persistent peat smoke, ash, pepper, and buttery toffee notes.

While the actual distillery remains undisclosed, industry experts speculate this single malt originates from either Bruichladdich or Caol Ila based on its heavily-peated profile and production characteristics. The whisky is frequently compared favorably to premium Islay brands like Port Charlotte, Laphroaig, and Ardbeg, offering similar quality at a significantly lower price point.
