We are a brewery and would like to migrate from Beersmith to this. I do not have confidence in the efficiency estimator. I put exact known recipes in and get a high OG by about 4 points. So I did a test. I set up the perfect mash tun with no loss and a simple recipe. 10 lbs German Pale, 5 gallon batch and 75% efficiency. If I run the math by hand and a potential extract of 1.038/lb of grain, I get 1.057 OG yet the software says 1.059. Here is the math 38 x 10 lbs x 75%= 285 285/5 gallons is 57 or 1.057 Anyone understand this?
