Yes, i do. With sprayed on star san. Because condensation forms on the cling film then drips backinto the wort.

Yes I've got a Coopers bucket like that. Waiting on a new tap.
But I've also got a couple of other FV's that come with screw on lids that have seals.
People take the seals out and use as a big rubber band. I just loosen the lid slightly.

Yeah those buckets do not seal well. Now I understand why you would even consider cling foil.
Better to use something like this https://www.ebay.co.uk/itm/Plastic-...ood-Storage-Fermentation-5l-65l-/253316638283
One lid with a rubber ring in it which you push on the barrel. And then a big screw lid which secures the other lid in place.

Wouter I think you are missing the point the members are using cling film because they do not want to use a lid or haven't got one and are not worried about seeing a bubbling airlock.

What's with all this "sealing your fv up" stuff?
Your brew produces copious amounts of co2 which by its nature will force out any oxygen in your vessel, as it's heavier than air.
So as long as nothing can fall in and you don't disturb the vessel, you will get a natural layer of co2 sat on top of your beer keeping it fresh and un-oxygenated.
Yes I use lids, no they don't seal, no I don't even bother pushing them on anymore. They get laid on top and I ignore the thing for 2 weeks...

Ha ha. Yes, if it was as simple as CO2 being heavier than oxygen, we'd all be dead. The protection only lasts as long as the beer is vigorously producing CO2.

Which exactly why sealing the barrel as good as humanly possible is necessary. As long as the barrel is sealed then the only way in and out is through the air lock and you're CO2 blanket is maintained. If the barrel leaks air then air simply mixes in.
Hi!
I think necessary is far too strong; it's only your opinion (although many believe the same thing). I certainly don't seal my FVs; I do leave the lid on loosely. The next experiment is open fermentation of a mild ale.
The only reason I use sometimes use cling film to get a seal on the FV lid is to ensure that the airlock bubble rate is accurate and I find that useful in determining how the fermentation is progressing. If it weren't for this I wouldn't bother.

I think the point was that the seal IS NECESSARY in order to maintain the protection of CO2. Whether maintaining that CO2 protection is necessary is entirely subjective.
2 weeks in an unsealed fv will result in the loss of the CO2 blanket. Breweries that use open FVs do so for a short period of the fermentation.
