I apologize if this has been covered. I have had two commercial brewers (both went to Siebel) tell me to dry hop with the beer at room temp. When the one guy told me about it, I didn't make much of it because I wasn't dry hopping at the time. The second guy (who I know better) mentioned it on a recipe he gave me for his Amarillo-Citra pale ale. He specifically mentioned dry hopping with the beer at room temp. When I asked him about it, he said that dry hopping with the beer cold will bring out vegetal flavors from the hops. I was out with some homebrewing buds last week and I mentioned it and a few of them were surprised and a couple didn't believe it. One asked, "what about putting hops in the cold serving keg?" and I didn't have an answer. Anyone care to chime in?
