Domed lid for SS Brewbucket 7 Gal

Also because I ferment inside a fridge which is sealed I imagine the atmosphere inside it is probably made up of mainly CO2.

I'd never though of it that way. You're almost certainly spot on with this! Far easier than any external capture!

I'm now imagining people fitting an airlock to the top of the fridge!

I'm going to have to get a box to fit my glycol chilled fermenters in to keep my CO2 blankert on the outside haha

Is that the balloon championed by brulosophy?I’m waiting for them to do one their tests on this. I’m pretty sure there would be no difference to a no ballooned cold crash , given their other tests.

I don't bother. I've never had an issue with it before even on NEIPAs.

Me too with the set up but doesn’t the liquid in the bubbler or blow off get sucked in?

Not with one of these

Yes. I've never used one though. I'm firmly in the camp of "I don't worry about oxidisation, and have never had an issue" (though I don't brew NEIPA).

I’ll probably give it a go then. Maybe crash down to 14c for dry hop then down to 1c for a day.

I must admit that I have experienced alarming colour degradation with my NEIPA’s when using a bottling bucket, despite blasting it with CO2 prior to bottling. I am hoping that closed transfer will either reduce or eliminate this.

Blasting a bucket with co2 will just mix a lot of CO2 into the existing air. It won't purge it of oxygen.

Imagine filling your bottling bucket to the brim full of beer. Then sticking a hosepipe into it and blasting water in for a while. You don't have a bucket of pure tap water - You have a bucket of diluted beer (even if you pour in gallons upon gallons of water). The same applies to mixing gasses as it does to liquids: You'll have a lot of oxygen left in your bucket.

 

[WM7793]

Yes I agree with you. At the time I was hoping to replace some of the oxygen with CO2 to minimise exposure. I am now waiting for hardware to arrive (Tri clamp fitting with keg posts, plus new bottling system) to allow pressurised transfer ot the beer to a WilliamsWarn bottling system. This will enable me to purge bottles prior to filling.

Just to clarify matters here.
I have experienced colour degradation when bottling NEIPA’s using a plastic bottling bucket and bottling wand.
I never said that the bottling bucket was full (23L), in this instance there was only 19L therefore there was some headspace.
I tried to purge the headspace with CO2 to minimise oxygen.
The first half bottles of NEIPA maintained its colour due headspace being purged but the second half of the batch was affected as the beer was exposed to more oxygen during bottling the remainder beer.
Solved problem by closed transfer to bottler.
