I usually leave my beer in the primary for 3-4 weeks and have found this works better than moving to a secondary fermentor. My question is this: I just started kegging and love it...if I have a brew ready to move from the primary to a keg, can I rack over and purge out the oxygen in the head space and leave the beer under say 10-15 psi for a period of time without hooking up to co2? I would keep the keg cold 35-38 and just consider it longer conditioning time? I would appreciate your experience and comments
