Inspired by our worm tubs, weve sourced casks from other producers of oak-aged spirits who also employ worm tubs to make their liquid wares. The first in our Craigellachie Cask Finishing Collection is our award-winning 13 year old Craigellachie Single Malt finished in Bas-Armagnac casks sourced from the northernmost part of Gascony, in France.
