Your bittering addition is about double what I use...I target 40IBU's (bittering addition) for an AIPA. You'll have to wait and see how it tastes. Depends on your utilization, body of the beer and AA%. These will all effect the perceived bitterness.
Interesting regarding the 40 IBUs target for the 60 minute addition. What is your average AIPA gravity?
Have you ever tasted SSOS? Just wondering what you thought of it.
Jim, when I saw the hop bill for this recipe, I knew you were thinking of SSOS. But keep in mind that hops are just one part of the equation. Maybe the reason the high IBU level works in SSOS is because of the grist bill, which balances it. I dunno, just thinking out loud.
