Equal parts of Simcoe, Centennial, and Citra for me. Love that combo.
I've been working on my upcoming IPA recipes and this is one of them. 2 oz Nugget @ 60, then 1 oz of each Centennial, Simcoe, Citra @ 5, flame-out, and dry hop. Maybe an extra ounce of Centennial for dry hop. I'm also going to do the same schedule, but replace the Centennial with Chinook.
