This winter I built a keezer and will be kegging beer for the fist time. I am new at this so please bear with me. My first keg will be easy, hook it up, force carbonate, and then turn the regulator down for dispensing. But what do I do if I want to add a second keg a few weeks later? I can't turn the regulator up or it will mess with dispending the first keg. I could use the valves on the distributor to control the CO2 but this seems too random, but then again, that may be the whole point to the valves. Ideas?
