Bunnahabhain 18 Year Single Malt Scotch Whisky
Bunnahabhain Single Malt Scotch Whisky is made from fresh Optic barley, which is lightly peated to approximately 3 phenol parts per million. Once the barley arrives at the distillery, it is milled and mashed with pure spring water drawn from the Margadale River. The water, which travels through an ancient bed of limestone, is transported by pipeline to the distillery and as a result, avoids travelling through the peatbogs of Islay.
Once the barley has been mashed, it is fermented in washbacks made of Oregon Pine for nearly three days. While wooden washbacks are more expensive and difficult to maintain as compared to stainless steel washbacks, they absorb a portion of the heat generated during the fermentation process and thus, create a lighter and more rich whisky. Following fermentation, the wash is distilled twice, first through Bunnahabhain's copper-pot wash still and again through its copper-pot spirit still. Then, the heads and tails of the distillate are removed by Robin Morton, Bunnahabhain's stillman (Morton began working at the distillery in 1978), before the whisky is allowed to mature at Bunnahabhain's warehouse. The sea-facing warehouse, which rests on the banks of the Sound of Islay, enjoys a cool, salty breeze that adds a touch of salt to the whisky as it ages. "Over the years, you get this slight salty taste," says Andrew Brown, Bunnahabhain's distillery manager. "The older the whisky gets, the saltier it becomes. It's not overpowering — it's just a hint." Bunnahabhain 18 Year Old Single Malt Scotch Whisky is matured in combination of used sherry and bourbon casks, before it is bottled without the use of chill filtration.
