Has anyone ever used nitrogen 16g capsules to cream a already primed keg?
I have some on order and was wondering how many to use in a keg that i prime with corn sugar instead of co2.
As long as you hit the keg occasionally with more CO2, it will be okay. Otherwise, the partial pressure of CO2 will drop too much as you dispense the beer. Realistically, you'll need a regulator for the N2 as well.
