I have a brewbuilt X2 and have been using the pressure pack for about 4 brews now. The latest was a heavily dry hopped IPA and I have been using a hop bong to drop hops under pressure, oxygen free. I love the fact that the beer is carbonated when it's done and avoids oxygen (had a nice IPA spoil because of oxygen contamination). The biggest issue I have is transfers. For this heavy dry hopped IPA, I cold crashed down to 40 degrees over two days, but the dip tube kept clogging and turned into a nightmare, so I'm trying to figure out how I will adjust next time. I would have thought cold crashing would have prevented clogging from hop matter. Is 40 degrees not low enough? 2 days for cold crashing not enough? Do others use a mesh bag for dry hoping? This obviously can't be done without depressurizing and opening the fermenter. Last question, when to install the floating dip tube, I have been doing this just before packaging, but I suppose it could be installed earlier, and backflush with a shot of co2 before packaging.
