I’m force carbonating my beer and bottling from my keg for the first time. I’ll be using a picnic faucet with a bottle filler with the tip cut at an angle. I’ve seen a few videos of the same set up, but with the addition of a #2 rubber stopper plugging the bottle opening.
My question: Is the rubber stopper a necessity for bottle filling directly from a keg?
Also, I plan on force carbonating with 35-40 psi for 2-3 days and lowering to 2-3 psi for filling.
I appreciate any advice.
