Q

I have been bottling in bombers for three years without issues. Following my normal process I have had four detonations and everything has been a foam fountain for my last three batches. What could have changed to cause this?

A
Bottle bombs are really scary because glass shrapnel can cause severe injuries. The first question that always comes to my mind when hearing about this problem is “how old is your glass?”
