Hello, I believe I have a infection the source I am not sure of. This was my second brew, My first brew I force carbed and some beer went up the CO2 line maybe the regulator. The taste has went from very nice wort and green beer before I put it in the keg to a Sour smell and Taste. The Sour Taste and smell seems to be getting stronger. I can change the lines and sanitize the Keg easy enough but what about the regulator. Mind you that I am a Newbie that is still trying to learn the ropes. Right now I don't feel good about dumping the beer but I don't see a good alternative. I only have the one keg to work with. The sour smell is becoming more of bad milk. Give me some advice as to what you would do. I know I wont force carb again. Thanks and Cheers back to enjoying yellow tail Kolce beer.
