Ardbeg An Oa is singularly rounded, due in no small part to time spent in the distillery's unique gathering vat, where whiskies from several cask types - including sweet Pedro Ximenez, spicy virgin charred oak, and intense ex-bourbon casks - familiarize 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 flavor.
