I usually carbonate my kegs at 34 psi for 48 hours at around 68 F with good results. I just kegged this morning and want the beer ready (and cold) to drink in 2 days' time so i popped the room temp keg and CO2 in the fridge. Now my question - I know cold beer absorbs CO2 more quickly, so set at 34 psi and around 40 F when should I expect the beer to be done at around 2.5 volumes?
