I have a kegerator with a tower and I've been drinking a keg of blonde ale for a for weeks. I have some friends coming over this weekend so I haven't been drinking it for a few days. I poured a beer last night and it was 100% foam. I opened the fridge and the regular had a psi of 30! I have no idea how long it's been at 30. My guess is last weekend I filled a growler to take to friends house. I purged the keg last night and set to the correct psi. Poured a couple times and it's all foam, no liquid coming out. I just checked again this morning and the psi stayed but the beer was still all foam. Anything I can do to fix it other than pour foam glasses. Interesting to me is once the foam turns to liquid I thought the beer would be super carbed but actually seemed less carbed.
Only put enough pressure on it to seal the lid and the carb level should drop. Vent it every now and then as well
I wouldn't think you'd need to leave gas on it. When I take gas off of a keg and still drink it the carb goes down...that's what I'm basing this off of haha. Just take as much c02 pressure that you can off of it without losing a seal on the keg.
I've had 2 kegs that I over carbonated in the last month. Here was my procedure: 1.-Remove the gas line to the keg 2.-Vent all of the pressure from the keg 3.-Let it sit for a couple hours and then release the Co2 again. After doing that 3-4 times, I was able to get it just right. If you leave the gas line on, you're not fixing the problem because you're just going to vent what you just put in. Or in your case, just leave the PRV opened for 24 hours and then check again.
When that happens, I generally turn off the gas and pour over the next few days using just the pressure that is escaping the beer into the headspace. It takes a few pints over a few days for things to settle down. You could also vent the keg from time to time to hasten the process. Unfortunately, there's no hard and fast rule on how long this will take. It may be perfect in time for this weekend or it may not be. If it's still overcarbed, reduce the serving pressure and make the best of it. It's nice to pour perfect heads, but people tend to be pretty forgiving with homebrew (mostly because it's free).
Your gauge is reading the set inlet pressure, not the pressure of the keg which is much higher (a check valve keeps gas going in one direction only). Your beer is carb'ed to 30psi which is easily correctable. As mentioned, you want to vent the headspace and leave the gas line disconnected. The excess gas in the beer will move into the headspace. If the keg is full this may take multiple re-venting's (new word) as you have lots of beer (CO2) and a tiny headspace. If you only have a gallon or so it will correct itself with one purge. It's likely (and not a problem) you may vent too much here, just reconnect the gas line and set-forget. If thirsty during this process just pour yourself one a few minutes after a vent . . . the off-gassing beer should give you enough headspace pressure to push out a tasty one, sans foam.
I haven't done this, but I've heard of people attaching a picnic tap to the liquid out and flipping the keg upside down then blowing the foam out of the tap while disconnected from the gas. I'd guess that would work if you are in a rush.
OP has foam because his beer is over carbonated and the CO2 is breaking out of solution when pouring. I don't see how turning the keg upside-down will fix that. The foam will keep being made (As the beer is dispensed) until this beer's CO2 level is reduced.
@PortLargo @mikehartigan @CADETS3 @ghostinthemachine Thanks for the help! I vented the keg, turned off the gas and poured a few glasses last night. Poured kinda slow but they were perfect pours. Cheers!
I understand why the OP has foam. CO2 will come out of solution faster if you agitate the keg by flipping it upside down. I know if I pour an overcarbed beer into a pint glass and agitate it with a fork the CO2 will come out of the beer faster than just letting it sit there and waiting for the bubbles to dissipate.
I followed some advice on the interwebs that soled my over carbonated keg problem rather quickly. It's anti-intuitive though, I'd suggest giving it a shot since it worked for me. 1) Turn down the pressure on your regulator to something low... maybe 5 psi. 2) Disconnect your gas in, and liquid out from the keg. 3) Vent the CO2 from the keg 4) Connect the CO2 fitting to the liquid out dip tube. 5) Vent pressure. 6) Let the CO2 bubble up through the keg and vent the pressure a few times 7) Pour a glass. 8) Repeat steps 4-7 until satisfied. The first time I did this, I took too much carbonation out of solution, and had to carb it up some more
