Wow...not being a kegger, I'm not sure, someone may come along in a bit...But havin said that the thing that occurs to ME at least is a sanitization issue. Your beer is over the time it's in the keg/lines, it is getting infected with something...I would look at your cleaning and sanitization process....it reminds me of the bars that don't flush their lines repeatedly and some of their bers taste like crap...

I gotta tell ya, just between us girls, that Revvy is HOT. Very tall, gorgeous grey hair and a terrific smile. He's very good looking in person, with a charismatic personality... he drives like a ****ing maniac! - YooperBrew
