Love those bottle bombs. Brewed up a nice Porter (think Black Butte Porter in flavor) last 4th of July. Had it in primary for 4 or 5 weeks (don't have my notes on me). Been in bottles since. Tasting great. Than sometime with in the last month (haven't had one for a while, been drinking my Dunkelweizen instead) one or two of them must have blown. Went to get a few out of the box the other day to put in the fridge and just about got cut. Inspected the box some more and found two bottles were broken. One of them had the side completely blown out. I'm not positive if that caused the second one to break or if it was a bomb also. Either way, had dried beer on the floor and tiny shards all over the box. Moved the remaining ones from that box to the fridge and am properly disposing of them LOL. They seem overly carb'ed now (after being what seemed perfect for months). From now on, I'm not just going to let the siphoning whirlpool action mix my priming sugar. I'm going to very gently stir with a sanitized spoon.
Good learning experience and good thing they're in my basement and in boxes.
