The intro postings from fizzypish got me thinking:
Are swing tops safer than crown caps.
I can see that the pressure required to pop off a crown cap would be massive and the bottle would break first!
But what about the swing top? Would the pressure escape past the rubber seal?
Remember I am not talking of a leaky seal and not getting any carbonation.
Has anyone first hand info on potential bottle bombs in swing tops venting excess pressure?
Has anyone suffered a swing top bottle bomb?
If no answers forthcoming then someone will have to do a hydraulic test!!
I overcarbed an entire batch of coopers European lager with a mix of swing-tops and coopers plastic bottles. Some of the swingtops showed evidence of a some liquid bubbling/seeping out between the seal and the bottle/white stopper. This happened on 5 or 6 bottles but they were still massively carbonated, i.e. they sounded like a champaign bottle when popped. None of them broken.
The coopers bottles were solid as a rock with the only difference being that the cap was bulging at the top when compared to a different batch.
Hi Will
all of the swing tips I have filed over the last three months have sounded like champagne bottles being opened. thankfully none have any signs of leakage or breakage. I get the feeling those rubber seals are pretty tough specially when the porcelain lid is being held in place by two metal rods.
