Had a bottle of big daddy IPA from the Speakeasy brewery in San Fran last night. Fantastic beer, really hoppy and with a great mouthfeel, definitely one to emulate. The site has this info:
Malts - Pale Malted Barley, German Munich
Hops - three hop additions of pacific northwest hops (including a dry hop)
Yeast - Speakeasy Ale Yeast
