I overcarbonated 50 bottles and think they will all spew badly . How can l save the contents? Some in Grolsch bottles, rest in good old refillable bottles. I drink one with a meal so maybe chilling just short of freezing, one at a time might work? Any better ideas?
Well you don’t want them to blow so I would keep them cold. I’ve had luck recapping
Get them super cold freezing temps. Then pop the topthe foam will blow off and recap them.
With the capped bottles, put the bottle in a bowl, crack open the cap just enough to release pressure and a bit of foam, and give it twenty minutes to reduce pressure. The bowl catches whatever spewed out so you don’t waste the beer. Be careful that a bottle doesn’t explode causing bodily harm. I agree with @brew_cat to keep them cold. These bottles at warm temperatures could be dangerous. There could still be fermentables left for the yeast to consume leading to even higher pressures.
