That Chocolate and Roasted barley is gonna darken the beer up for sure. I'm not sure if I'd want those is my IIPA, but to each their own. Maybe add a bit of Caraoils for a softer finish? Have you run the recipe through beer-smith or tasty brew or something? Also make sure to get started on this soon. I just brewed my Graduation Imperial IPA a week or two ago, and I'm worried about it being aged well enough for May 20th. Good luck!
