I tell you I would hate to have to ever pick just one brewery as my favorite but if some put a gun to my head and told me to choose just one Long Trail might just be the one I would pick. I have had a lot of beers I really liked but then it will turn out that particular beer is the only one from that brewery that I care for. I have honestly only had a couple from LT I didn't really care for (they can scrap the blackberry wheat if you want my opinion).
Anyway enough of my babbling. If you like Chocolate Porters go get yourself a bottle of Culmination
