I’ve had a few imperial stouts aged in whisky barrels however I’ve never really had much joy with them. What I enjoy in a single malt (peaty) I don’t think transfers well to an imperial stout. This one however is really good. I really must pay closer attention to the kind of single malt barrel being used in future! It’s incredibly smooth. Chocolate flavours from the stout and a delicate caramel sweetness. Earthy metallic notes, leather and gentle, sweet tobacco come through too. Far too easy drinking, 375ml came and went too fast.
