Bunnahabhain sits at the northern tip of Islay, reached by a single-track road that tests the patience of anyone arriving at the wrong tide. The distillery was founded in 1881 by the Islay Distillery Company, and unlike most of its island kin it has built its reputation on unpeated spirit — a deliberate departure from the Islay norm that the marketing department now describes as a virtue and which was, in truth, simply what the founders decided to make.
The standard 12 year old has been the house introduction for decades. This cask strength expression presents the same maturation regime without the customary reduction to 46.3%. What emerges is a fuller, rounder version of the familiar profile: sherry casks doing most of the talking, the spirit's natural oiliness preserved, and the coastal character — that faint brine which visitors to the warehouses know intimately — amplified rather than softened.
Batches vary, as cask strength releases must, and the ABV has moved between roughly 55% and 58% across recent iterations. The distillery bottles these at natural colour and without chill filtration, which is consistent with the broader Bunnahabhain policy adopted in 2010. The result is a whisky that rewards water sparingly added, though it stands well enough neat in a decent glass. Among unpeated Islay malts it remains the benchmark, and the cask strength format is how the distillery's supporters have long preferred to drink it.
