My lovely wife bought me a mini keg (64oz) system for Father’s Day. Now I’m still very green in brewing, I’ve only done 3. But I have questions on how this works. Do I have to do any priming sugars in the keg? I assume no. If forcing carbonation, I think I’ve read to pump it up to 20 psi and then do you bring it down to recommend psi for the brew and let it sit for a couple days? I guess it doubles as a growler as well. If I were to fill it up, and tap it, what should the psi be?
