Hi, I overcarbonated my corny. I've been keeping it off co2 and bleeding the keg to nothing. Once I put co2 on it quickly foams up too much again...

I know when I filled it, I put over 5 gallons so there wasn't a ton of headspace, but I should be at least down to the 5g mark by now.

When I pour a pint and wait, it does go down to a drinkable level, but what would could I be doing to improve the issue and minimize the foam?

cheers :mug:

check serving line length vs temperature. If that isn't it, shut off gas and leave purge valve open overnight.

There was a post about this a while back where the OP hooked up the gas line to the liquid post on the keg and by allowing the gas to pass through the entire beer 'column', it eliminated most of the dissolved gas. Or something along those lines.

I'll see if I can find that thread. Who knows, I could be talking out my ass.

once I read the statement about the in and out lines being reversed I ran (ok I sprinted) to check.. but not the case. But I notice bubbles in the beer line to the picnic tap. I'm befuddled. no other keg I've done had this problem. Only thing I did different was add more than 5 gallons because I had a lot of extra from my brew day...

bubble in the beer line is a new one on me...

  1. What are the details of the process you used to carbonate this keg?
  2. What is the keg temperature?
  3. What is the serving and/or storage CO2 pressure?
  4. What is the beer line length?
  5. What is the beer line ID?
  6. Keggerator or Keezer?
  7. Is full length of beer line at keg temperature?
The above are all things that can cause foamy beer. Without details on the above, it would be not be possible for anyone to diagnose your issue.

I had similar issue and mine tuned out to be bad oring on co2 dip tube. I had set psi at 10 for over week and tons of foam but wasn't overcarbed. With help here I was able to figure it out. Just another area to find the culprit. Gl.

Fair enough:

[*]What are the details of the process you used to carbonate this keg?
Force Carb

[*]What is the keg temperature?
36F

[*]What is the serving and/or storage CO2 pressure?
currently 8lb

[*]What is the beer line length?
about yay long (over 4')

[*]What is the beer line ID?
beer line ID?

[*]Keggerator or Keezer?
Keezer

[*]Is full length of beer line at keg temperature?
Yes

just looked again, not sure where the air bubbles are coming from in the line. weird... Could I have a air leak?

Bubbles are probably CO2 coming out of solution. If it were a leak, you should be losing beer out of the leak.

What pressure did you force carb at, and for how long? Did you do any keg agitation during forced carbing? Did you try to serve at higher than 8 psi initially, and if so, at what pressure?

Short beer lines are the most common cause of foamy beer. To prevent foamy beer line length needs to be balanced for the beer line diameter and carbonation level. You can learn more about it here: http://www.mikesoltys.com/2012/09/17/determining-proper-hose-length-for-your-kegerator/

Google or search this forum for "keg balancing" information. There are several factors at play, but it's not overly complicated. It all comes into focus after about 15 minutes of reading.

Btw, ID refers to your beer lines. It means inside diameter.

What I would do, after reading about keg balancing, is to determine how many volumes of co2 you want based on the type of beer. Using a carbonation table (http://www.kegerators.com/carbonation-table.php), you determine serving pressure and temp to reach your desired co2 volume. Once you work all that out, I'd let the beer sit at that pressure and temp for several days. If you have foaming issues after that, start looking at your liquid lines as the cause of your balance issue. This is where Soltys' calculator comes in handy. I wouldn't be too worried about head space yet.

Buy a 15' length of 3/16" ID beer line and try that. If it pours too slow for you, cut off a foot or two.

When carbonating, seal the lid with about 30 PSI, purge the air out a couple of times, and back the regulator down to the appropriate serving pressure for your beer style and the serving temperature. Leave the pressure alone until the keg is empty. Follow this process and you should never have over-carbonation problems.
