Fining with gelatin under pressure

[ba-brewer]

The old style carbonation caps work best for the gelatin rocket as you can get more of the solution out.

Gelatin injector works great. Timing not that critical, should be injected into a chilled keg 34F, but I’ve done them at ambient and it worked fine. Bloom the gelatin for 5-10 minutes then hit it with microwave bursts until 165F. Injector was fabricated from a meat injector from the BBQ section at Lowes.

I use a gelatin rocket. I make my gelatin solution, I add it a 20oz PET soda bottle, add a carbonation cap, carb the bottle to about 6psi above what the keg is at, then use a jumper to shoot the gelatin into the gas post of the keg. See picture below:

I obviously don't normally have coke zero left in the bottle, make sure it's clean and sanitized before attempting . I also typically use one of my stainless steel carb caps from my fermzilla allrounder, so that's why I have a liquid ball lock on one end, but I'm pretty sure these red caps are gas only (at least it's always super dang hard to get a liquid ball lock on them) so if you have the plastic carb caps I recommend you use two gas quick disconnects.

One difference on mine is a piece of hose on the cap to the bottom of the bottle. And I use a smaller bottle (12 oz).
