I froze my hops last year, and wasn't particularly thrilled when I finally got around to putting them in a brew (a few months later). Thawed out, they pretty much looked and smelled like cut grass. :?
I used them anyway, and the beer turned out okay, but it was such a small amount that I am not sure they were even really noticable.
This year, they are going straight from the vine into the (late) boil. :mrgreen:
