Hold on to your hats, folks, because we've gone and bottling some 23 year old Ardbeg! That's right, our Single Cask Series grows larger with the addition of a 23 year old single malt Scotch whisky, which was distilled in February 1991 by the legendary Islay distillery, set aside to mature in a bourbon cask and eventually bottled in January 2015 with an outturn of 216 bottles.
Age: 23 years old
Cask Type: Bourbon Hogshead
50.6% ABV /70cl
