Dumbarton 25 Year Old 2000 Unicorn is a rare and characterful Lowland single grain Scotch whisky, distilled at the now-closed Dumbarton Distillery and bottled exclusively for The Whisky Barrel as part of the highly collectible Unicorn Series. Distilled in 2000 and matured in a first fill Oloroso sherry hogshead (#TWB1043), this exceptional single cask was bottled in 2026 at a natural 56.6% ABV, yielding just 259 bottles.

As stocks from Dumbarton continue to diminish, releases like this offer a unique opportunity to experience whisky from one of Scotland’s lost distilleries. The first fill Oloroso cask brings depth and richness, layering the whisky with notes of dried fruits, chocolate, and warming spice, while the long maturation enhances the smooth, creamy character typical of well-aged grain whisky.

The Unicorn Series label pays tribute to Dumbarton’s most famous guardians—the legendary “Scotch Watch” geese. These Chinese white geese famously protected the distillery’s bonded warehouses from 1959 until 2012, becoming an enduring symbol of Dumbarton’s history and folklore.
