I use whole hops. I do know that some folks pick up on certain flavors more than others, for instance, I know a fella that picks up on diacetyl very easily. Also, I have read that certain hops do impart some grassiness, Saaz being one of them.
QUOTE my all Amarillo IPA uses pellets and the dry hop seems to be lacking this property but the aroma is much stronger than my experiences of using whole hops.
This may be why I don't notice grassiness, I generally dry hop IPA's using hops like Amarillo, higher alpha type hops. Maybe that is the key!
