I have 4 litres of cider in a demijohn that I'd like to force carb so I can drink it while the summer is here (finished this Wednesday).
Has anyone any suggestions on how to do this?
Putting it in a 19L corny will just waste stacks of CO2.
Carbonator caps arrive next week
You could bring it up to me and we try the carb stone? Still loads of Co2 though. I think you're in soda stream territory though.
