Skip the crystal malts in an IPA or IIPA recipe. According to Mitch Steele, "minimizing use of crystal malts in IPA, [which] adds a level of sweetness and malt intensity that [can] kind of mask the hop character … as the beer ages, the crystal malt immediately turns into that dried raisin, fruit character which really knocks the hop character down."
Your hop schedule is kind of a mess. What are you shooting for?
Why two different bittering hops?
Why an addition at 40 mins?
The Columbus at 10 may or may not compliment the flavor and aroma of the citra and simcoe.
Here's what I would do:
- pick a clean-tasting, high AA% bittering hop and stick with it. Most of your IBU's come from this charge.
- add a lot of late addition/flameout hops.
- use no more than three kinds of hops and pick ones whose flavors complement each other. Don't use a dank hop (columbus) and a citrusy hop like Citra together.
- consider doing a hopstand - letting the wort sit for 30 minutes after flameout at 160. This increases hop flavor and aroma.
Definitely dry hop it. Use whatever hops you used for late additions.
Something like:
1.5 oz of Columbus(or Simcoe) @60
1.5 oz of Citra @15
1.5 oz of Simcoe @15
2.0 oz of Citra @1
2.0 oz of Simcoe @1
Then dry hop with 1.5oz each of Citra and Simcoe.
Plug the recipe into beersmith and tweak the recipe until you get the IBUs (and IBU:OG ratio) where you want it to be.
Also, you didn't say anything at all about your mash profile. I like my IIPA's dry and not malty, so I do long mashes (90-120) in the high 140's but if you like malty IIPA's then a 60 minute mash at 152 is probably what you want. I don't think I would mash any higher for a hoppy beer.
