I know this question has been asked before, but none of the threads I have found have actually explained the phenomenon that is occurring. Essentially, when I dispense the beer from my keg, it pours complete foam, but when the foam settles out, the beer in the glass is completely flat. Anyone know what is going on here?
This doesn't seem to be a simple issue of balancing the system. I could reduce the pressure in the keg, increase the line length, etc. in order to pour a slower or less foamy glass. What I don't understand is how the pour can be complete foam without being noticeably carbonated at all. It is as if, once the beer reaches the glass, all the CO2 instantly bursts out of solution as foam, thus leaving the beer devoid of CO2. But I don't understand why this would happen, if this is what is actually happening.
