If I follow his grist %s, and change the SRM to 965 for the D180 as an example, I get a projected SRM of 18.3, just a bit darker than his projection of 16.9. Still no idea where to get something @ 1900EBC here in the states, but for a 6G batch batch, its only 2.8oz so I guess it cant offer much more than color at that rate?
