I have been intrigued by barrel-aged gins and even have bought a couple but both were lightly aged and on not pungent wood, as it were. That changes with the new releases from The Botanist.
One is Islay Cask Aged and the second is Islay Cask Rested Gin. The latter “has been matured in cask for a minimum of 6 months, and Aged has been matured for a minimum of 3 years.”
The Botanist has a big selection of botanicals that just might meld with an Islay cask.
