Ardbeg An Oa is a single malt from the Ardbeg distillery on Islay, named after the Mull of Oa peninsula. Whisky matured in a range of casks, including Pedro Ximénez sherry, virgin charred oak and ex-bourbon, is married together in a large oak 'Gathering Vat'. The result is a smoother, rounder Ardbeg, with smoke balanced by toffee, dried fruit, aniseed and warming spice.
