I'm not sure it's the peach that's causing the off flavor right now. I think what really needs to clear first is the smell. It's really hard to ignore. I took a little sample and set it aside. I'll give it another taste in a little bit and see if I can describe it. I do have some hoodies I can put over the carboy. I might even just throw it into my closet; it won't see any light for a month in there.
