I thought I would share this practice.
Like most people who keg and force carbonate, I used to force carbonate my kegs by attaching the ball lock gas connector and laying the keg on its side, turn the co2 tank to 30 psi and roll said keg back and forth for a few minutes or longer. Next, stand the keg up leaving it to sit overnight at the 30 psi. Not too much of a PITA but thought there is a better way.
I had an epiphany, leave the keg upright, attach a liquid connector to a gas hose and attach that to the liquid out post. The co2 now travels down the dip tube and, in my opinion, carbonates the beer more efficiently. While at the same time attaching the original gas in hose to its proper ball lock. Turn the co2 tank to now 10psi instead of 30 and carbonate from both directions. No lifting, no rolling. Keg stays in place and is ready to tap sooner.
