Hey all, a neighbor friend of mine has a Danby kegerator and has had recurring problems with foaming, which I've tried to help him out with, to no avail. And I'm no newbie to setting up and balancing a draft system... Here's what we have to work with and what we've done so far:
- Danby fridge holds 40 degrees, more or less, so to get ~2.5 volumes of CO2 we have the regulator set at 11-12 psi.
- We have 5.5 - 6 feet of B3 3/16" tuibing from the coupler to the faucet.
- Using the standard sanke coupler that came with the kegerator.
- Using the standard shank that came with the kegerator.
- Switched to a Ventmatic forward-seal faucet.
- He normally has Yuengling Lager or Premium on tap.
- We have tried shutting off the gas and venting out the keg 2 or 3 times over the course of a few days to bleed down the dissolved CO2.
- We have tried adjusting the dispense pressure up to as high as about 14 psi and down as low as about 8.
- We have cleaned the shank, there's no gunk anywhere in the system.
- We don't see any signs of air bubble leakage anywhere into the system.
Each time we do a pour, be it the first glass or the 10th, it's at LEAST half foam, if not more. What's more, the foam is meringue-y and rocky. Wierdest, though, is that the stream of beer coming out of the faucet itself is bubbly, like the CO2 is breaking out. Our faucet connection to the shank is tight, and I can't see where any air is leaking in. I have had Yuengling on tap at my house before, and the stream of beer that comes out is sparkling clear.
I'm stumped. We've gotten every variable addressed, as far as I can see. I'm out of ideas, so can anyone see if I've missed something? TIA,
