Just got a small (will hold the 23 litres and that's it) fermenter. Only noticed today just before I was about to put the brew in to start that it doesn't have a rubber O ring seal in the lid.
any thoughts on....
Where I could get one (live out of town, closest town doesn't have a great deal of resources)
Do I really need it (e.g. is there something I can dodgy up from around the house or will it just work fine without).
I realise it's probably best to have one for a better seal and hence better fermentation, thought I would ask the forum and see if anyone's had any experience with a fermenter without a rubber seal in the lid.
