So last night I grab a bottle of Alesmith IPA, that I had to drive to Massachusetts to get, popped it open and poured a glass of foam. After seeing that the foam wasn't going to settle, I dumped it, and slowly tried to pour another glass and the sucker foamed up again. The beer that I did see looked like ginger ale with all the carbonation in it. I tried to taste it and it didn't seem funky.
So would this be infection or overcarbonation? I have never seen a commercial beer act like this and was wondering if anyone else has, either from Alesmith or some other brewery.
