Octomore 16.1 is distilled from 100% Scottish Mainland Concerto barley, malted to 101.4 parts per million phenol — among the highest peat levels of any commercial whisky. Despite this extraordinary peating, the 16.1 is crafted for delicacy: matured for five years entirely in first-fill ex-bourbon barrels, which lend vanilla and caramel notes that frame rather than mask the intense smoke. The five-year age statement belies the depth achieved through cask strength bottling. Released at 59.3% ABV, non-chill-filtered, at natural colour, as part of the Octomore Series 16 annual release from Bruichladdich Distillery, Islay.

Bruichladdich Distillery is located on the western coast of Islay, Scotland, established in 1881 and revived in 2001 after a period of closure. The distillery is owned by Rémy Cointreau (acquired 2012) and operates under its 'Progressive Hebridean Distillers' identity with a commitment to Islay barley and terroir-driven production. Octomore is Bruichladdich's super-heavily peated range — the most heavily peated whisky series in the world. Each annual series explores extreme peat levels alongside premium cask maturation, released in three editions: the '.1' from Scottish Mainland barley; the '.2' using experimental cask combinations; and the '.3' from Islay-grown barley grown on the historic Octomore Farm directly above the distillery.
