A long time ago (well, sometime last year anyway) Carwyn Cellars and Tallboy & Moose joined together to brew a luscious imperial stout by the name of Dark Side of the Moose.
Although half was tapped at the Thornbury bar last August, the rest was split away to sleep a sweet sleep inside a bourbon barrel, quietly awaiting the perfect moment to resurface as The Moose Strikes Back.
While inside it's become uber-chocolatey with some added barrel vanillan creaminess and figgy fruitiness.
Carwyn will be tapping it on Wednesday afternoon along with a keg of the original Dark Side and the Apritang apricot sour, also brewed by the Preston brewpub.
