Keg and the problem goes away

I'm curious why so many here are suggesting sanitization as the most likely cause of the problem. It seems to me, an unsanitary bottle is just as likely to turn out flat as it is to 'gush' (if the bacteria killed the yeast) - Also, I think it would be fairly obvious from the smell/taste if it was an infection issue. Do folks have stories/text I could read to get some more info on this?

Infection / sanitation was my first thought. I tasted some of the remaining beer that I was able to capture from one of the gushers and right away I could tell something was off. I thought that maybe because of all of the activity the yeast did not settle into the bottom of the bottle, but now think that the taste was due to the infection. The taste was a yeasty flavor that was not present in the healthy beers. It was an IPA and was very clean and dry, other than being hoppy of course.

Sounds like a wild gusher yeast to me. I had one spoil a whole batch once, took it down to 1.000.

The bacteria doesn't kill your yeast, but it does chew through sugars that yeast cannot and ends up overcarbonating your beer. They also might have a weird geometry making for pretty explosive nucleation (think mentos and coke on Mythbusters).

My vote is for a wild yeast....need better sanitation.
