I am getting ready to keg my brew for the first time. I have ALWAYS bottled before. So, once I put it in the keg, do I just put the top on it, hook it up to the kegerator and apply the CO2 to it and hold the tap handle until the beer starts to come out and then let it sit that way for a couple of days? I read somewhere that you should start it out at 10 PSI then drop it off and then bring it back up to approx 2 PSI for serving... does this sound correct? Any and all help in regards to kegging and carbonating would be great!
