Here’s a question for the math nerds. I want to start adding gelatin finings to the fermenter without any oxygen ingress. Here’s my plan.
I have a small soda bottle that I will pressurize to about 10 psi via a carbonation cap. I’ll then transfer the gelatin finings into the fermenter that is at 0 psi through the ball lock gas post on the lid (see picture). Also,
This will be after a cold crash of the beer. Being that the fermenter isn’t able to take pressure beyond 1 or 2 psi, will the small soda bottle introduce enough pressure on the fermenter? I can’t imagine that it would make that much difference. Obviously the head space is reduced with the finished beer, so maybe it would?
If this doesn’t really work, I will just do it in the keg. However, I would prefer to add finings to the fermenter.
This is essentially what I want to do but with the fermenter.
Interested if this worked? I'm thinking it would work - the pressure is in the bottle to push out to the fermenter, but the only issue is that any pressure above the couple of psi the fermenter can handle will pop out through the lid seal.
My only comment is that I've usually found that adding gelatin tends to work a bit better when added to the keg before racking chilled beer into it. It just mixes completely that way, whereas squirting stuff into a fermenter just doesn't.
