Foamy beer dispensed from keg

Post by brayson » Thu Jun 15, 2017 11:08 pm

Hey folks, I have been struggling with one of my beers.
I am not new to home brewing, but still an early novice. I have built a 3 tap keezer, and have 3 different beers on the go at the moment.

Two of my beers dispense fine, hut I have an oatmeal stout, that leaves the keg as nothing but foam. Before it even enters the beer line it is foam and gaps of CO2.
I have tried 2 different kegs, 3 different disconnects, de-pressurizing and re-pressurizing.
I'm at a loss. Does anyone have any ideas?

Have you tried dismantling your tap, cleaning thoroughly and reassembling? I recently had this issue... not as severe but the problem ended up being my tap. (Not a perlick)

I'm a bit unclear as to the variables you've experimented with here - you've tried the same beer in 2 different kegs? Or you've tried different beer in 2 different kegs but from the same tap?

Just trying to determine what is the commonality.

Foaming can be caused by many things, however. Common causes are that the beer itself it over-carbonated, or your CO2 serving pressure is too low (to keep the CO2 in suspension) or too high - search for keg line balancing, there are some formulas that take into consideration your beer line diameter, length, and CO2 pressures.

@TheGrainBarrel - Yep, dismantled all 3 taps and cleaned them obsessively.

@mikeorr - Yes, I siphoned the same beer into a different keg after running low on ideas. I have also tried through all of my taps. When looking at the line, it is already foamy as soon as it enters the beer line after leaving the keg.
I fully depressurized the beer in question, and used the same method as my other beers to carbonate again, to no avail.
I'm looking at the line balancing now, but at a glace I'm within these thresholds.

Anyone wanna come over for a beer and help troubleshoot in person?

What is your serving pressure?

Tear down your posts. Take a picture of your poppet, post, and dip tube. If it goes into the beer line as foam it's where I would look. Also take a pic of your disconnect.
