So the 12g canister fits nice, a filed down Allen key can sort the triangular screws...
Next logical question...
How much do we prime the PET bottle? As usual for longnecks or less?? Anyone over/under carbed yet?
Phil,
CO2 is more dense than oxygen, meaning it is heavier and will always give you a nice little barrier between your wort and oxygen. Provided you don't disturb it, it will sit happily for weeks.
Cheers
