I am going to keg my first ever batch of beer from a kit I bought from Morebeer.
I am a little confused with the purging process: I am planning on cleaning and sanitizing the keg before use... Then, for purging, do I do this BEFORE I fill with beer, or after, or both?
From what I have read, I am understanding to fill the keg with CO2 before it has beer in it, release, and do this again 2 or 3 more times.. Then, fill with beer? What I am not getting is how do I not introduce oxygen back into the keg when I pull off the top and rack into it? Do I then purge the headspace a few times, finally setting it to my serving pressure?
