Can I store ginger beer in screw-top metal flasks? Answered
I used to make ginger beer as a kid in England when there was ample access to screw-top soft drink bottles, but now they are like hen's teeth. I have been saving these sturdy, metal (aluminium, I believe) screw-top flasks which seem to be lined with some plastic material.
So, can I ferment my ginger beer in these flasks, as opposed to the always stipulated "glass screw tops"? I am sure they are strong enough to withstand the pressure buildup.
