A friend sent me this bottle of New Holland Dragon's Milk around a year ago, I think. It's an imperial stout aged in bourbon barrels.
Really wonderful vanilla, chocolate and bourbon nose. Nice aroma. Medium bodied. Quite strong bourbon presence in this with an almost milk chocolate flavor backing it. Definitely stronger on the bourbon flavor than some others though not in alcohol heat. The bourbon faded a bit as I got used to it with the chocolate and vanilla coming to the forefront, making this quite enjoyable. This is also relatively readily available (or at least I think it is though it has been a while since I looked) so it would make a good choice for someone interested in trying bourbon aged stouts for the first time.
