Keg question
Keg question
I have for some time use two kegs in a converted fridge for my beer dispensing, I use an adjustable faucet and 1m of 3/16 beer line ... the question I have is every now and then I get a brew with a foaming issue.
One issue is, I can get a perfectly good beer that holds pressure (i.e. doesn't increase and needs topping up with C02 when dispensing), it is a very clear beer, but after a while, approx. halfway through the keg, its starts to foam excessively when dispensing?
The second issue is recently, using a Lalbrew yeast, although it fermented out correctly to its FG, after I have dropped it into the keg it starts making pressure, to the point that no C02 is required when I dispense. The beer is clear but foams allot. I usually have to fill 3 glasses to let it settle?
I am a bit baffled with it, as generally I don't get foaming and pour a good pint straight from the faucet.
Cheers.

Re: Keg question
Your problem sounds like you are not allowing your beer to finish fermentation and are relying on an fg calculated by a recipe based figure. Try leaving it a few days longer before kegging.

Re: Keg question
Thanks for the reply... using the same yeast next so will be more thorough.
I also did some more research on the archives and realised I haven't changed the dip tube valves for a while and this may be letting gas by. Because on some brews one of the foaming issues is when its 50% through, and then its starts. I would assume as the beer is clear and fermented out and needs regular gas to feed dispensing, so a gas pressure bypass problem in the keg system?
Cheers.

Re: Keg question
Are you just topping up CO2 when it doesn't flow?
You need constant fixed pressure on top to maintain the carbonation.
If you are using a regulator what PSI is it set to??

Re: Keg question
Aside form the current couple of foaming issues, I keep the pressure at the right psi to temperature for the type of beer on the regulator. If i am not using the beer for a while, i disconnect the C02 and put a gauge on, and the pressure is normally maintained. Then reconnect when i use.
I am thinking at the moment i have poor seals on the dip tube? Which may explain foaming halfway through using the keg on stable clear beer?

Re: Keg question
Are you using cornies? If so I reccomend that you use a float takeoff

Re: Keg question
Yes cornies… i just googled the float system. Looks good, i will order with my next brew batch. Cheers.

Re: Keg question
Is the problem with the same keg or both?
There's a slim chance your beer out dip tube may have a pin hole in it. I had one when I first got my kegs, one keg would pour fine but the other was at least half a glass of foam. Eventually found a small hole just below beer level so it was drawing co2 from the space above the beer as well as the beer itself from the bottom of the tube.
Just a thought

Re: Keg question
Its both kegs, when dispensing clear beer and pressure is maintained. I have bought some new o rings, but will check the dip tubes. Cheers.

Re: Keg question
If the beer out dip tubes in both kegs have holes that would be very rare
