Yep I've herd of glad wrap streatched over lid with pin prick in it! I'm no so trusting I'm too paranoid of baddies getting into brewYou can ferment in anything you like , I have a few different types of vessels I use
All are fitted with taps , some have airlocks but I ignore them anyway
The Coopers/Mr Beer DIY vessel is the easiest to dry hop not having a screw lid but having the tap so high up from the base annoys me
Long answer: No reason. Get a lid and make sure the gas has a way out and critters don't have a way in.quick question. Someone gave me an extra bottling bucket. I don't need two. Any reason why I can't buy a lid and use it as a fermenter?
