I had a few D'Arcy's Choc Stout tonight. Damn it's very chocolaty! I've not had many chocolate stouts, few here and there. On draught my main comparison would be Porterhouse's choc truffle stout but D'Arcy's is far more chocolatty.
It's served a bit too cold for my liking but half way between what I call "a bit cold" and "a bit too warm/too old" (as in the pint's an hour old!) you get this deadly chocolate after taste just as you swallow. It's yum and I want more!
