I've had something similar happen. I was keeping home-made ginger beer in our refrigerator for some weeks after I'd made several bottles of it. Ginger beer is yeast, water, sugar, ginger juice, and a few other things. I didn't realize that - even at 3-4 degrees Celsius the yeast would continue doing their thing, albeit slowly.

I was sitting at the kitchen table, right next to the fridge, when a 750 ml glass bottle of ginger beer exploded. It took out another bottle along with the tempered glass shelf it had been sitting on.

Not only did it take more than an hour to clean up, the replacement shelf my wife ordered was the wrong one, so she had to order yet another replacement. It took ages to arrive.

I have not yet been allowed to make more home-made ginger beer, which is a shame because it's very tasty and is excellent for making cocktails in the summer.
