Last night I noticed my Pale Ale was quite foamy and was pouring much faster than the NEIPA I have in the same kegerator. I gave a short pull on the PRV of each keg until I heard the CO2 bottle refilling the co2, the pale ale had a whole bunch of pressure behind it (my rough guess would be 20-30psi judging by the sound) compared to the other keg(my guess is right around the 8 psi the regulator is at). The keg is halfway empty(or full?) and the first half poured issue free. The kegerator is a 2 corny mini fridge conversion, both kegs are fed from the same manifold and co2 is set at 8 psi. Not sure how this happened, I did notice frost on that keg last night so I upped the fridge controller a hair. The keg has been cold the entire time and the beer tastes fine so I doubt fermentation restarted or infection. Any ideas?
