So I just kegged an oatmeal stout a few days ago. I probably brewed it three weeks ago. I also did a batch of very low gravity beer with the third runnings. Both batches taste strongly of bandaids. Is this a flavor that's permanent or will it go away with time? This is the first batch of beer that I've ever done that I'd call "contaminated". The flavor comes through so strong that I just can't drink it.
