Alright, I'm having problems with my kegerator again! I've been down this road ever since I've started kegging and it's very frustrating to say the least.

I typically "boost carb" a chilled keg (40* F) at 30 psi and shake until it's a little under the volume I'd actually want (by taste of course). I then release the gas and set at 12 psi at around 43* F for my serving pressure.

I have a dual tap Danby kegerator and have 10 ft lines by the way.

It's been about a week since I kegged an APA of mine and it's now pouring straight foam! It's not only on the first pour, but all of the pours (this morning I tested it and I filled 4 pint glasses up with foam!!). It was a little frozen last night b/c I was playing with the temp gauge, but it's not today (I opened and checked).

I turned my gas off and it's not sitting with 12 psi that's in the keg and no more going into it. I've been kegging long enough to know when my beer is overcarbed and I don't think this is the problem.

What pressure do yall serve at b/c I'm thinking this may be my problem?

the problem with "boost" carbing, as you call it, is it's very easy to overcarb a beverage. A good rule of thumb I know many people follow including myself, is to NOT carb at Hi pressure...carb it at the serving pressure you wish to use. If you serve at 8psi, then hook your keg up to the co2, adjust to 8psi and let it slowly carbonate over a week or so..then you'll have perfectly carbed beer, and correct serving pressure as well. I can't even count the number of posts I read like that, where people have foaming issues after they force carb at high pressure.

How long is your dispensing hose? and what is the I.D.? Also 12psi is too high to be serving at.....you should be down closer to 6-8psi.

Basically sounds like your beer is now overcarbed....turn the gas off, and over the next day or so..go out and pull the let off valve on your keg to let off extra/unwanted co2....keep doing this until it releases no or minimal gas...then you can start over.

Well, I have 10' 3/16 ID beer hose. I have it off of the gas right now and I think that I'll try what your saying.

Thanks,
J

I've got 12' of 3/16" line and I serve all my beers at 12 psi, although I'm not sure about the temperature.

Could be an obstruction in the Out line. Try the above suggestion first and if its not a fix, vent the keg, pull off the out post and dip tube, clean it, re-install, and then check the tap line for anything like hop leafs or a glob of 'something', including the tap spigot itself.

Well, it is an APA and it's highly hopped, but I used pellets so I don't think that's the problem, but hey, I'm willing to try anything.

Thanks,

It's just overcarbed, nothing more. It's very difficult to decarb quickly too. Warm the keg up a bit, then pull the release slowly until foam comes out. Wait 4 hours, pull the release until foam comes out. Repeat again about 3 more times. Then chill it back down. Rather than boost carbing it at a higher pressure, try making the beer cold and shaking it at serving PSI. That will speed carbonation but it will never overcarb. It might take a couple days with a few shakes per day, but it will be right.

Alright, thanks Bobby. Yesterday I left the kegs in the kegerator, but purged the air out of them twice before setting at 8 psi and leaving it there last night. I didn't get a chance to pull a pint due to the fact I had a lot of work to do last night, but I will see tonight.

I'll give you guys an update later on.

Thanks,
J

I figure I have waited 5 + weeks for the beer to make it to the keg, what's another 5-6 days while it conditions at serving pressure. I did the force carbing thing a few times - not a pure success, but needed to get the beer ready for guests etc.

Yeah, well I think I found out what my problem is. I popped open one of the kegs and it wasn't frozen, so I assumed the other one wasn't either. IT IS, BAD! I poked it with a sanitized brewing spoon and I'd say 7" was solid ice that just pushed down into the alcoholic mixture of what I used to call beer on the bottom. I have both of my kegs out of the fridge now and once their thawed, I'll put them back in and reset to serving temp.

<------Frustrated with this damn danby.
