I've got a problem that is driving me to drink...pun intended. I generally use the set and wait method and it has worked fine for me over the last three kegs. this time I cold crashed my beer (black IPA) 24 hours in advance. transferred it to the clean and sanitized keg and pressurized to 12 PSI for 5 days. At this point i tested the beer and it was barely carbonated if at all. I pulled the pressure relief to ensure there was pressure in the keg and that was fine. I checked my connection with spray bottle of starsan and no bubbles. I did think that the poppet pressure relief may have been loose so I have tightened it. I isolated the other IPA on service (that is working fine) and cracked the pressure up to 20 PSI. I intend to wait 2 days and test again. Any suggestions? :-[
