Ardbeg An Oa is singularly rounded, due to time spent in Ardbeg\'s new bespoke oak Gathering Vat where whiskies from several cask types - including; sweet Pedro Ximenez; spicy virgin charred oak; and intense ex-bourbon casks, amongst others - familiarise themselves with each other. The result is a dram with smoky power, mellowed by a delectable, smooth sweetness. Hallmark Ardbeg peat, dark chocolate and aniseed are wrapped in smooth, silky butterscotch, black pepper and clove, before rising to an intense crescendo of flavour.
