Make sure the ingredients are as cold as possible. CO2 dissolves best into freezing cold liquids. Add thebatch to the Cornelius keg and seal. A perfect seal is necessary to properly carbonate. With the CO2 tankturned off, connect the tank to the keg and then turn the CO2 on. Use the regulator to ensure we arepushing in 50psi of CO2. You should hear the CO2 being pushed into the keg without any leaks. After 1minute, turn off the CO2 tank. Pull the tab on the top of the keg to release the oxygen. With the CO2 stillturned off, turn the keg on its side and roll it back and forth to help dissolve the CO2 into the cocktail.Stand the keg upright and turn the CO2 tank back on. Repeat the process 6 times.
