Pouring foam/no beer from keg.

[czmer1jw]

Hey all,

I been having problems with pouring beer from my kegarator. One tap pours the beer super foaming, like the whole glass was foam. My second tap isn't pouring anything, it starts out super slow and then dwindles to nothing. My co2 is set at 10 psi.

I would start with cleaning or Re-cleaning everything for starts, Just because at 10 psi I don't feel you should have an issue with it dwindling to nothing. I have had this happen before, for me it was hop junk clogged up in the faucet itself. So start with cleaning everything once more. And below are just some common things you will read for reducing foam. In my setup I run 10ft 3/16 diameter hoses.

• Use beer line that is at least 8 feet long

• 5-12 PSI

• Mid-low 40's temperature (liquid temp, not air temp)

• 48 hour keg rest after transport

hope this helps you

Thank you! I will have to clean everything and buy longer hoses on my day off on Tuesday. Hopefully it will work

Make sure all your o-rings are installed. I had a problem where one tap would pour nothing but foam; turns out I forgot to reinstall the dip tube o-ring. As for the no-pour, might be a clog somewhere. I'd switch the hoses from the 2 kegs, and see if it's the keg or the regulator. Also, put a sheen on keg lube on all your o-rings just to be sure they have a good seal.

also make sure your kegs aren't frozen

Thanks for the help. I have another question. I tried my beers in the keg and they both have a sour flavor it makes it impossible to drink. This all happened after I switched my co2 tank. Before the tank switch both beer tasted fine with no sour flavors.

Oh btw the one that wouldn't poor was due to being frozen... But no pools super foamy too

You might be overcarbed. If the beer froze it was down below 30 degrees which is going to be in the 2.9 vols range so won't pour well with short lines. Sounds like you need to get your keezer sorted - consistent temp around 40ish, fan(s) so there's cooling to the lines and minimal temp stratification, and long enough lines. Once the kegs are fully defrosted you may have to vent them for a few days to decarb.

Also assuming that it is overcarbed. Some people describe the overcarb taste as tart or sour.
Comment below pulled from another post...
"When CO2 is dissolved in solution it is in the form of carbonic acid, which may have sour or slightly tart flavor to it with a very dry aftertaste"

I believe it's over carbed. How would I go about fixing it? My last beer was an ipa in the same keg/tap/line and it didn't have this problem. Wonder why I'm having problems now

Disconnect the gas and vent it every time you think of it over a couple days, then try pouring again. It's overcarbed most likely because it got so cold - 10 psi at 37* will give you about 2.4 volumes, but if chilled under 30* it's more like 2.9 volumes. Did you figure out why it got to freezing temps and have you gotten that fixed yet? Once you get your temps stabilized use this chart to determine your needed psi.

Okay cool thanks. I completely vented all the gas out. I poured a little and it tasted fine. The problem I have is when I hook the gas back up it get over carbed. I'm going to go buy some longer hose this weekend as I think mine is too short. Also, my inconsistent temp is due to this fridge /freezer. I bought it off someone as a package deal (with kegs, taps, grain, etc) and the fridge itself doesn't work well. I'm going to be investing in a chest freezer here soon
