I have 24 bottles downstairs of a tasty brew. Well, at least the part that didn't cover the ceiling and my entire body. You see, it was a high sugar beer from my first attempts, and I naively bottled after only 2 weeks. Tons of sugar farting out C02.
My tester bottles from the bottom of the batch with heavy sediment were flat out dangerous. One repainted the ceiling. The next was opened outside with a motorcycle helmet on and only boxers. The cap cleared the yard and landed in the street.
The low sediment tester was decently bad, lost half of it.
So, any trick that will prevent the rest from exploding? I doubt they're dangerous, but they're gonna blow somewhat.
