I’ve recently picked up chest freezer that I am going to convert into a keezer in the near future. While I’ll still be working from picnic taps for a while, my plan is to move a kegged American Brown from my lager fridge (currently set at 33*) to the chest freezer (which I will set at 42*). My question is: do I need to reset the CO2 level in some way to maintain my preferred carbonation level of 2.4 volumes?
This Keg Carbonation Calculator
tells me that to achieve 2.4 volumes, the pressure should be set to 7.8 psi in the lager fridge, but should be set to 12.2 psi if I set the chest freezer to 42*. Since the beer is already carbonated, do I still need to make the adjustment?
