Here is what I gathered from Nathans original post. I brewed this beer a few months ago and it was awesome! You wont be disappointed.
Nathan adds gypsum to the mash. How much I dont remember, but the quantity is irrelevant anyway without knowing what your starting water profile is. Something along the lines of Tasty's water profile he outlines in his APA would be perfect.
