I was wondering if anyone can help me identify an off flavor in a recent American Pale Ale I brewed. It is a very grassy kind of vegetable off-flavor. I've read of this happening with dry hopping for too long and from using homegrown hops. MY recipe is below, I did not dry hop and the hops all smelled fresh. I planned on doing a 30 minute hop stand at 180 F but overcooled my wort and started the hop stand at 120F. Did this lower temp add the grassy flavors? After the hop stand I whirlpooled the wort and racked into my fermentor.
For water I use bottled deer park water. I have never had this off flavor before, so thanks in advance for any help.
