I would like some ideas as to possible reasons I am having bottle bombs. I just had one today from a bottle that was bottled in November!! The bottle was a 17 ounce bottle-- bought new-- but has been used on other homebrews. The bombs show no favorites though-- have had 12-17 and 22 ounce blow. I don't keg because I give a lot away and I like to have at least 10-15 different varieties. HELP!! I've only had about 6-7 blow but it is such a pain to clean up. My bottles are on a 6 shelf unit.
