Am brewing a Czech Dark Lager that calls for .5# of Blackprinz as steeping grains. Blackprinz is in the list of grains, but its PPG is listed as 36. Was investigating my efficiency for my steeping process, and found discrepancies with what I achieved and what the editor said I should get. Presumed it was related to the default 35% efficiency which I see can be changed. In further investigation with the home brew rep at Briess, he indicated that I could expect very little if any sugar (thus PPG) from Blackprinz. He said 35 was way too high...possibly 3.5 PPG. Anyway, can this be changed by me, or must Brewer's Friend change this...appears I can only customize "fermentables"?
Thanks!
Thanks!
