That looks like a more potent version of the one I will be making soon (~18 lb grain bill). I am using 1 oz. of Nugget for 60 min, .5 oz of Liberty at 30 min and another .5 of Liberty at flame out (Alesmith Speedway Stout hops
Alesmith also adds 3 lbs of DME at flame out. I decided to add some oatmeal instead (to the mash, of course).
