Highland cask Imperial Stout Imperial stout fermented in a freshly emptied Highland whisky hogshead (Blair Athol distillery). Brewed with an array of roasted and crystal malts, and fermented with a historical yeast. We cast the wort for this stout directly into the barrel to undergo primary fermentation. An experimental process for us, warm fermentation in a freshly emptied barrel has proved itself a unique process to draw out intense flavours from deep within the wood. Expect treacle toffee, dried fruits, cinnamon, caramel and chocolate.
