Well here's my calculations based on an extract utilization formula I found...GramsExtract=(IBU*

[email protected] of boil)/(.35*10). Solved for IBU (53), then added Warrior until IBU was achieved.

Used Beersmith2 with 62% efficiency at 5.8 gallons to fermenter with 90min boil. Don't see how the 70IBU in posted recipe sheet is possible with these amount of hops.

Other hops/grain bill were a simple calculation; 1300gallons/5.8gallons=224-factor so CTZ at 90min for example is 7*16/224=.5oz.

OG=1.072

IBU= 170

SRM=6.1

ABV=7.8%

Rahr = 17.1 lbs

c60 = .48 lbs

Corn Sugar = 14.4 oz

Warrior @ 90min = 1.1oz

CTZ @ 90min = .5oz

Amarillo @ 45min= .6oz

Simcoe @ 30min = 1.4oz

Cascade, Centennial, Amarillo, Simcoe @ WPool for 20min = 1oz each

Dry Hopping (Wasn't sure the days so just have dry hopping at 5 days each)

Dry1:

Simcoe = 1.6oz

Cascade = 1.25oz

CTZ = .70oz

Dry2:

Simcoe = 1.4oz

Cascade= 1.0oz

Amarillo/CTZ = .5oz each

Anyone else??

Edit: added extract formula found and recalculated to End of Boil volume. Also this is about 14oz of hops, my other calculation, using a smaller factor, make it around 22oz, and the grain bill would be way high.
