Total noob with fermenting under pressure/trying to avoid the oxygen suck back issue of cold crashing. Bare with me and you may have to explain it like I'm 5.
I'll be using a Fermzilla All Rounder to ferment under pressure for my first time. I've read a few different answers on cold crashing and just want to make sure I understand everything correctly. Assume I will be fermenting under 15psi, and I don't want to carbonate the beer much at all during the cold crash.
1. Can I simply just take off the spunding valve and set the temperature to 34 degrees? The lid has a gas and liquid post so I would assume no oxygen would get sucked in unless I had a leak?
2. Can I actually leave the spunding valve on or can oxygen still get sucked in through a spunding valve?
3. If questions 1 and 2 wouldn't work, should I just hook up CO2 from my tank and keep it at about 2psi during the cold crash?
Thanks so much!
