listened to this show again to get ready for my own attempt, and I didn't hear the AA% of the hops in either the regular or rebrew shows
the Deschutes brewer said the 85 min and 30 min additions gave 40 IBU
Justin used .99 oz at 85, and .99oz at 30
so
1 ounce each, AA = AAU
85 minute hop utilization = .245
30 minute hop utilization = .177 (both from How to Brew)
X x .245 x 75 + (X x .177 x 75) /6 (util formula from How to Brew) should equal 40 (IBU given by Deschutes for these 2 additions)
X x 3.4375 + X x 2.2125 = 40
5.65 X = 40
X = 7
7% AA assumption for the Cascades in the recipe?
