Went into 'storeroom' to put some beer into condition, and when i opened door there was a bottle on the floor, about a foot away from the shelves. when i picked it up it had this ...


As you can see, a hole about the size of a marble near bottom. Now, I haven't had this experience before, but i would have though if that bottle was under that much pressure it would just explode, hence the expression 'Bottle Bombs'
This bottle was on top shelf, about 3 and a half feet high, and not near the edge so i must have been some force to send it where it landed. It is also one of an older brew , and i wouldn't have said the rest was over carbonated!!
Anyone else seen this, and can put me out of my confusion??
