Any ideas? I have 2 identical kegs (5 gal). I brewed 10 gallons of an IPA and put 5 into each keg after fermentation (10 days) and crash cooled to 38 degrees for 5 days . I then transferred to the kegs and let them sit overnight at 36 degrees in my keezer. I then set 40 psi on each keg for 18 hrs ( my usual burst method). Then I set to serving pressure ~10 psi for a week. The problem is one of the kegs is mostly ~ 80% carbed but the other one is not. I left the uncarbed keg on 40 psi another 6 hrs and still not carbed. There is some carbination but very little. I recently (about 6 weeks) changed all of the o rings on both kegs and keep them conditioned with keg lube every time I empty them. I don’t believe there is a leak as I just used this keg for an Oktoberfest that was properly carbed. I bottled the remaining oktoberfest (same day) so I could use it for the IPA. I did not burst carb the oktoberfest as I let it lager for 5 weeks. I set 9 psi for the 5 weeks and it was perfectly carbed. Therefore I didn’t notice if the keg had slow carbonation until today.
I do closed transfer so the way I fill my kegs is to weigh the empty keg for a tare (8 lbs empty and 8.2 if I use my keg dry hop tube loaded with hops) and then fill to 50 lbs which gets me to the right level. Both of these kegs were filled with exactly 42 lbs of beer for my normal known fill level so I don’t think one has more head space than the other. I did pull the prv just to see if there was good pressure and there is. I’m at a loss as to why one keg is so slow to carbonate. Both kegs were purchased brand new about 6 months ago from Kegco.
