Can you help me fix this IPA recipe?

Interesting - would have thought 89 would be super bitter - I'm still a bit afraid to go beyond the "Style guides" that brewfather shows - perhaps I need to be more adventurous

89 modeled IBUs doesn't mean 89 real IBUs. The utilization curve gets pretty flat pretty fast above about 65 IBUs. Glenn Tinseth, author of the most commonly used model, totally rocks, and he did extensive testing, but not at those levels. 89 Tinseth IBUs is going to be more like 70 real IBUs.

sorry: brewersfriend says 85 tinseth and 99 rager. not 89T, its bitter for sure, but pretty smooth
