I'm new to Beersmith, tried putting in a partial mash recipe that have already brewed. Everything looks good, except for the final gravity number in the design tab of the program. I'm starting at 1.050OG, and pitching from a 1.6L starter, on a stir plate, using both Wyeast 3711 + WL565. The starter tab is optimistic about cell count, but either underestmates the attenuation, or doesn't carry it back to the design tab. In real life, I got 1.002FG, but the program suggests that I'm designing for 1.015FG, which I am not. The whole idea is that this beer is supposed to be super dry, (and carbonated at 3.2 volumes of CO2.) It looked like attenuation was grayed out, and I'm not sure how I would know to input specific percentages from intuition.
As a first time user, I'm sure that I'm missing something. I want to understand this part of the program, because this isn't the last time I'm going to try to design a low Final Gravity beer.
