I cracked open an SNPA clone that I brewed about 6 weeks ago, and the color seemed a little light, and then I got to wondering about the role of mash efficiency in color. I assume 80% efficiency, but actually got more like 83%, and the original recipe was based on 75% eff. As I understand it, for two versions of the same brew (same OG but different efficiencies), lower efficiency with more grain = more color, while higher efficiency with less grain = less color, even though the OGs would be the same. Is this true?
I ran hypothetical numbers in Beer Alchemy and it seems right, but I wonder what other people's experience is. If you are getting higher efficiencies, do you adjust your grain bill to reach a certain color, or do you just go with the original recipe, adjust your base grain to reach the intended OG, and live with a lighter colored beer?
