Can anyone offer some insight on an off flavor? I brewed BB English Brown Ale. Left in primary for ten days. Kegged it and put it under pressure...I have a habit of checking the carbonation as it goes. I checked it a little while ago. The beer has a slight tart flavor, almost like a white wine, with a slight warming effect in the throat afterwards. Can anyone tell me if my beer is bad, if it may get better with time, etc. If I did mess something up, can some offer insight to what it could have been?? Thanks in advance
