I'm trying to come up with an IPA hop schedule that is different from what I've done in the past. I've used Cascade, Citra, Simcoe, Amarillo, and Centennial before. What are some of your favorite other, less obvious hop combinations for an IPA and what flavors do they give? I have read about Warrior and Summit, and of course Columbus, but unsure of how best to use those. I wanted to use some Rakau or Galaxy but they seem hard to find. Thanks for any advice.
