Smoky Islay barley and roasted Mexican agave share a barrel in Kilchoman Mezcal Finish Single Cask 2013, an Islay single malt Scotch whisky finished in ex-mezcal casks. The island’s young farm distillery built its reputation on bold cask experiments, and this bottling is one of the more daring: spirit distilled in 2013, matured for years, then given a final stretch in casks that once held mezcal. Two smoke traditions meet in the glass peat and earthy agave on the nose, then pepper-dusted dark chocolate and smoky vanilla across the palate, with dried fruit carrying the long finish. One cask means one short run of bottles. Pour it neat for the peated-whisky drinker convinced they have tasted everything.
