Edition 15.1 of Bruichladdich’s Octomore was made using barley grown on the Scottish mainland and malted to 108ppm, resulting in a heavily peated single malt. This whisky was matured for five years in bourbon barrels, imparting aromas of smoked caramel, mango, vanilla custard, and barbecued pork on the nose, with bright citrus notes, smoked heather, and ground coffee.
