I have fridge space issues and I can't chill down my kegs to carb. I hooked one up to 30psi for 2 weeks and bottled from the keg to sample. All four bottles were very undercarbonated. I'm counter pressure filling so the issue is probably coming from the force carbonation. I just can't put my finger on what it is exactly.
At room temp you are probably only getting to just under 2 volumes of co2 with your current setup. Have you tried naturally carbing in the keg? I have done this at room temp with good results. Edit: just over 2 volumes*
So, weird situation here, at 30 psi at that room temp for that time you might get a bit more than 2,2.Are you sure your gas tank has enough gas pressure?.No leakages?
Im sure there is no leaking going on. I cranked it down to serving psi and poured a glass at room temp and carb was great. I then took some bottles out of the freezer and bottled from the keg so that I could chill them down to sample. All 4 came out flat.
Was there any excessive foaming? It would seem at that temperature that CO2 would come right out of solution as soon as the pressure was released.
30 psi at 66F should get you to about 2.7 volumes at equilibrium. It's quite probable that you had not yet reached equilibrium after two weeks.
ive had issues with caps and cappers recently. I bought one of the models that is on a pole and has a handle that comes down to cap the bottle. I was using oxygen barrier caps and it looked like it was sealed. no liquid leaking. However after sitting in the bottle for a week the beer was very under carbonated. I returned the capper twice and went with the more expensive floor model for corking and capping which fixed the problem. the butterfly cappers work well too but wanted an upgrade. I did a second test with the butterfly capper and the desktop capper that i return and after another week the butterfly capped bottle was still perfectly carbbed while the desktop capper wasnt. This is when I realized it was the capper and it didnt like oxygen barrier caps. Just something to ensure before chasing other things
