There's something undeniably bold about taking the maritime character of island malt Scotch whisky and running it through tequila cask finishing. Rock Island Tequila Edition is a blended malt — despite what the category field might suggest — drawing from undisclosed island distilleries and bottled at a confident 48% ABV with no age statement. It's the kind of release that will divide opinion before anyone's even pulled the cork, and frankly, that's part of its appeal.
The concept here is straightforward: take the peat smoke, brine, and coastal grit that island malts are known for, then layer in the agave sweetness and slight vegetal spice that ex-tequila casks bring to the table. It's a flavour marriage that sounds improbable on paper but has a certain logic to it. Both traditions — island Scotch and tequila — are spirits shaped by their environment, by terroir in the truest sense. Combining them isn't gimmickry so much as a conversation between two strong-willed spirits.
At 48%, this sits at a strength that lets the whisky speak without shouting. No chill filtration would be expected at this ABV, and that typically means more texture and body in the glass. For a NAS release at £60.75, you're paying for the novelty of the finish and the blending work that goes into balancing island malts from multiple sources — never a simple task.
Tasting Notes
I won't fabricate specifics where my notes would be speculation. What I can say is this: expect the hallmarks of island malt — coastal influence, a thread of peat smoke, the mineral quality that sea air seems to impart — interwoven with whatever the tequila casks have contributed. That typically means a warmer sweetness, perhaps some tropical fruit character, and a peppery edge that standard bourbon or sherry casks simply don't provide. The interplay between smoky and sweet is the territory this whisky occupies.
The Verdict
I'll give the Rock Island Tequila Edition a 7.7 out of 10. This is a whisky that earns its score through sheer originality and the confidence to be different. It isn't trying to be a classic island dram — it's trying to be something that hasn't quite existed before, and it largely succeeds. The 48% ABV is well-chosen, giving the blend enough power to carry the unusual cask influence without overwhelming the malt character underneath. At just over sixty pounds, it sits in that middle ground where you're not gambling your evening on something untested, but you're still investing enough to expect quality. For anyone who enjoys island malts and has grown curious about what unconventional cask finishes can achieve, this is a genuinely worthwhile bottle. It won't replace your go-to Islay in the cabinet, but it wasn't meant to. It's meant to make you think, and it does.
Best Served
Pour it neat and give it five minutes to open up in the glass. If the ABV feels assertive, add no more than a few drops of water — just enough to unlock the middle notes without drowning the coastal character. A classic Highball with quality soda and a twist of lime would complement the tequila cask influence rather nicely on a warm evening, though I'd suggest trying it straight first to understand what you're working with.
