I have a Summit Kegerator that I was having some foaming issues with (1/3 beer, 2/3 foam per glass). After taking some advice from the forum, I tried lowering the temp while monitoring a glass of water inside the kegerator. After turning up the temp to max cooling, it got so cold in the kegerator that it froze the glass of water. When I tried to pour a beer at the low temp, I found that my CO2 has run out after only having the tank a week. I got a new tank, checked all the connections and found some leaks which I fixed. Now, the beer is better. There still seems to be quite a bit of foam at the pour but once it settles, I'm getting about 3/4 beer and a 2" head. The head is much thicker than before and tends to stay around for quite a while. The question now is, how can I fine tune the system to reduce the foam a bit more. Currently my CO2 pressure is at 12 psi, inside of fridge is around 30 deg F. The outside of the tower is cool to the touch. Any suggestion would be appreciated.
