Built my keezer today and I have had a hefe aging at room temp in the keg for a couple weeks. I am a noob to kegging, but I was dying to get this beer carbed up and in the keezer. I turned the regulator up to 40 pounds since the beer was at 65 degrees an did the rolling method for about ten minutes. I put the keg in the keezer and left it all afternoon and decided to try and pour one tonight, keep in mind I set the regulator down to 10 pounds, and when I poured the beer all foam..... After the foam goes away the beer is fairly flat. I need some suggestions as to what to do, and yes I know I was impatient!
