First, let the keg cool in the kegerator. After ensuring you have the right coupler for the type of keg or beer you’re serving (heads up, most domestic beers will use your ‘D-system’ coupler), open the CO2 tank and set the pressure. This is a good time to make sure the regulator valves are fully open. Adjust that regulator to serving pressure, starting at 10 PSI — make necessary, incremental adjustments to balance the keg. Guarantee that the regulator is pressurized before tapping it. Once that’s out of the way, connect the keg coupler by twisting clockwise until snug, secure the lever, and then… Nope, that’s it! Pop that bad boy open and get the party flowing!
