I see there are other keg-foaming questions on here, but they seem to usually be related to commercial kegs or have answers that I've tried (hastily).
I have a keg of homebrew brown ale and a brand new 2-tap Edgestar Kegerator which has a roughly 1ft tall stainless steel tower. We upgraded the hardware on the kegerator to have a manifold between the two CO2 lines as well as threaded disconnects to support either corny keg (ball lock) connectors or commercial kegs. The kegerator has been cold since Monday, and the keg was chilling for 24 hours on Monday/Tuesday in the kegerator before we started force carbonating it.
We are force-carbing it because we have a holiday party on Friday (tomorrow!) and we want to have it ready by then.
Finding various techniques for force-carbing, we ended up going with 20psi for one day and 30psi for another day, with rocking the keg every couple hours in between, before letting the CO2 out of the head space in the keg and getting it back down to 10psi.
We now have the liquid line connected, and nothing but foam is coming out, pint after pint. The beer itself, once the foam fades, is very flat.
Here's what other people have suggested to fix that I've already confirmed are not a problem:
- Get it cold - yep, the keg and the beer coming out of it are cold
- Use 3/16" ID tubing - it already came with that
- Make sure the lines are cold - they are, and the faucet itself gets cold once it starts flowing
- Make sure the lines are long enough - they are about 3', which according to the L = (P - (H x .5) - 1) / R formula they are more than long enough for 10psi
- Clean the lines - these are clean, brand-new lines
- Make sure the lines don't dip below the top of the keg - they're currently spooled up on top of the keg
Based on other answers and other websites, here's what I've tried:
- Setting the regulator to zero, clearing CO2 from keg, then slowing raising it back up - no luck at 5, 8, 10, or 12 psi
- Crank up the pressure to 10-12psi directly after clearing CO2 from keg - no luck
So is there anything I can do to get this ready for tomorrow evening? Is it undercarbonated (since it tastes flat) and the pressure is wrong for pushing it out, or is it overcarbonated and the flat taste is because of the foam? Do I really need to by a tower cooler fan to blow the cold air up into the tower? Or is there no hope for having it ready by tomorrow and we just need to let it sit at 10psi for 2 weeks?
