Any idea what causes the insane amount of foaming that occurs w/ some bottles? I opened one of my Father-in-law's bottles (Sam Adams Clone) a few months ago and it foamed right out of the bottle. I thought it was altitude, but we're lower than he is. I helped a friend brew a few weeks ago and he had the same problem. It doesn't happen w/ the whole batch, just one.
I want to say I've had this happen w/ commercial beers, but I'm not sure. Any thoughts?
infection, or unequal amount of priming sugar. Either you did not equally mix the priming solution in the beer and some bottles had more than other. Or, some of your bottles were not clean enough and not properly santized.
I rack on top of my priming sugar (after I boiled and cooled it); I don't think that's it. So, I guess maybe I didn't dunk the bottle into my star san all the way or I left a booger in the bottle and didn't notice it.
