Five years is sufficient to age a good bourbon in the American South’s hot, humid summers and mild winters. While Scottish law requires no less than three years maturation, the colder weather of Scotland means that most single malts are aged 10 years before release. There are a few 8-year single malts out there but that is not common.
One wonders why Ardbeg, known for a superb 10-year and a collection of standout NAS whiskies, would release a young whisky like the Beastie, and as a permanent selection at that. Other whiskies are made with spirit as little as 5 years old, but more typically, distillers hide the spirit’s youth behind an NAS label. The Wee Beastie label proudly proclaims 5 years of maturation. I expect economics plays a part. If Ardbeg can figure a way to market their younger spirit in a way that does not sully their reputation, they can increase output and thus market share.
