Hi, everyone,
With all of five brews under my belt (hey, you've got to start somewhere) I have noticed that some of my beer bottles foam rather excessively when I open them. So far all my beers are bottle conditioned, and most of them have come out quite well, with the beer being clear and the sedimentation staying at the bottom of the bottle.
However, sometimes I will open a bottle (carefully) and immediately the foam will rise out of the bottle, and the carbon dioxide come out of solution so vigorously that it stirs up all the yeast from the bottom of the bottle. This happens (as far as I can see) randomly, with one bottle being fine, and another bottle (same size, same temperature, same brew, same amount of carbonation, same careful way of opening the bottle) being "wild".
What causes this? I have a suspicion that solids in the beer may have something to do with it, since my first full mash brew (which has a few issues with excessive trub ending up in the fermenter) is more prone to excessive foaming upon opening the bottle than are kit brews and partial mash brews. Still, I opened a bottle of my Belgian strong ale this afternoon, and much to my surprise it foamed so strongly that practically all the yeast was lifted from the bottom. None of the bottles from that batch have done anything like that so far.
I know that over-carbonation is the first common suspect in this case, but trust me, all bottles have the same amount (within small tolerances of course) of carbonation.
What's happening here? Any ideas?
Cheers!
