As one of your readers from the UK I resent the term "thin like an English porter". There are plenty of amazing, full bodied and robust porters being brewed over here, you've just been drinking the wrong ones!
I mean thin as a mouthfeel term, no disrespect at all! I like porters to have a thin, easy drinking characteristic to them and this did, which is actually a compliment, I assure you! =)
