I guess I added too much dry hops to my IPA. The beer didn't have this flavor before dry hopping. Then I added 5 oz of leaf hops since I got a decent harvest from my garden this summer. I literally crammed them in the carboy and gently tilted the carboy several times to wet them down. At bottling, the beer now has a tea flavor but not astringent in any way. It's actually pleasant, and I got a really nice aroma in there, but it's not what I was going for.. Maybe this is what is considered a grassy flavor? I always figured these problems would be due to fresh hops, but I guess 5 oz was a bit too much. I'll see what happens when it bottle conditions. Maybe it'll fade.
