Making some apple soda with store bought juice and a ginger bug. Previous juices have needed 2 days to carb and that was supposed to be today. Yesterday, one self vented, so I burped all 3. Today, one exploded. Never expected it.
Is store bought apple juice different than other store bought juices? Is my ginger bug different than last time? Idk.
The ginger bug is probably what affected it here, my wonderful neighbour has given me a few homemade bottles of ginger beer before, and one's exploded in the fridge, the other had enough pressure build to blow the lid off when opening from a remaining 2 inches of dregs.
Apparently, there's just something about ginger fermentation that really builds pressure
I think I said the opposite of that? Tempered glass does just suddenly blow up sometimes.
Anyway, I was a glassblower for 15 years and yes, mechanical stress builds up in glass over time as it gets bumped, tapped or knocked around. Small scratches and nicks can significantly weaken older glass too.
