I have a belgian golden strong that has been in bottles for just over 2 months. I've had the bottles lagering after two weeks in the bottle. I used WLP 570 and am getting this musty twang to the beer. I had the beer analized by a judge and he said the musty flavor tastes like oxidation. He said the beer tasted old. This is my first time using the WLP 570 yeast and am wondering if this flavor is from the yeast that hasn't dropped out of the beer yet being that the beer is young and not old. Can anyone that has experience with this yeast tell me if this flavor that I am talking about is yeast derived and will drop out over proper aging. If not I guess I screwed up somewhere and oxidized my beer. Everything else in this beer tastes great. It just has a finish that is not quite right.
