I had a bottle explode on me a few weeks ago and not really sure why. Every other bottle from the 20L batch was fine so far. It literally made a bang Did not have room in fermentation press for once and of course I then get a bomb. I dissolved my glucose as usual and added to bottling bucket etc. The bottle that exploded was from near bottom of fermenter as I put an x on them. Only thing I did different was use protafloc, but doubt that has anything to do with it. Could have been extra sugar at bottom of fermenter some how.
