There are plenty of hops that have good qualities, but are rarely talked about or seen in homebrew recipes. This thread is for them. Amarillo, Centennial, Columbus, Cascade, Chinook, Citra, Simcoe, Noble hops, East Kent Goldings, Magnum, Willamette and their ilk don't belong in this thread.
Give us a few less popular hops you like to use and tell us why you like them. Describe them. I'll give mine later.
