I stand corrected. It was at the San Diego Brewing Company's tent that I tasted this. Frickin' awesome...it's the ChocoLatte Porter : http://www.sandiegobrewing.com/beer/beers.htm
Their Hopnotic IPA is pretty good too....but not as good as Stone's or Pliny the Elder, IMHO. If you live in this neck of the woods, try that porter. You won't be sorry.
