Can you compare Simcoe to, say, Amarillo?
I've read they go very well together, but I don't know the characteristics of Simcoe.
I use them together all the time. Simcoe is a fairly high alpha 13.2 hop on the citrus and grapefruit side. Simcoe is by far my favorite hop, and has made it's way to the top of the list for IPA and IIPA brewers both in home and commercialy. It, like Amarillo is somewhat hard to come by most of the time.
