So instead of filling the keg with starsan and pushing out with CO2 to purge oxygen, I pushed CO2 retrograde through the dip tube with the gas port open. The CO2 is from the keezer at 36F. Like a cold front pushing out a warm front, the temperature difference between room air should cause viscosity between the air in the keg and CO2 which should limit mixing. I leave a temp probe in the gas port and watch for the temp change. After I see the temp change I let it go another 30-60 seconds then close the gas port. Seems like an easier way to purge oxygen before kegging, anyone have any thoughts on this?
