I brewed today trying to hit an O.G. of 1.050 and using an efficiency of 67%. My measured O.G. was 1.060. Is there a way for Beersmith v2.0 to calculate what the extraction efficiency of the grains are between the estimated O.G. and the measured O.G.? It would be nice to figure this out so I can make adjustments to the software so I could brew beer that will stay within style guidelines if I choose to push the ABV to the maximum limits. Thanks!
