I am a newb and from what I read when I keg my first batch I just set the co2 to 12 and let it set for a week. Do I refregerate it while I am force carbing it or do I cool it first then force carb it or do I force carb it then refregerate it. please help.
Remember one unassailable statistic, as explained by the late, great George Carlin: "Just think of how stupid the average person is, and then realize half of them are even stupider!"
"I would like to die on Mars, just not on impact." Elon Musk
The beer won't absorb much CO2 at 12 psi when warm, so it does need to be refrigerated while force carbing. But there's no reason why you couldn't put a keg full of room temp beer in your fridge and put it under pressure right away -- there's no need to wait until it's already cooled before starting to force carb it.
