The Glenfiddich Experimental Series has launched with Glenfiddich India Pale Ale Cask Finish, the world’s first single malt finished in IPA craft beer casks. The result of the project, overseen by Malt Master Brian Kinsman, is a liquid with a zesty citrus note followed by sweet vanilla and a hint of fresh hops. Pale Ale Cask Finish is the first in the series, which will include a number of unexpected variants over time. 86 proof.
