This is true. I love Beersmith, but the FG prediction is useless.
To see why I say that, put 100% corn sugar into one gallon water in a "recipe". Then do it with 100% crystal malt. Now, a 100% corn sugar "beer" or wine will ferment to .990 in real life. 100% crystal malt won't ferment much, if at all. But Beersmith gives you the same FG estimate whether you're using 100% crystal malt, 0r 100% corn sugar.
The FG estimate in Beersmith just comes as a figure of like 75% of the the OG, which we all know is a guess at best. In other words, the FG prediction has to come from you! Using the yeast strains probable attenuation, and the mash temps, and the ingredients, you can come up with a great guess as to the probably FG. We can help you until you get some experience!
