OK, so I have always bottled my brews, and never have I ever had this happen. I came back to eat lunch at home today, and I got to pop open one of my American wheats, and I hear this cracking noise as I pry off the cap. I look to see that the whole lip and about a half inch down had broken off with the cap, and the cap was still attached to the now broken top of the bottle. So the bottle is obviously trash now, but did I do something wrong to do this? The carbonation on all the wheats are perfect, but this sucker wasnt carbonated at all. Bad bottle?
