Hello everyone.
What formula to people use when estimating Final Gravity? I'm interested in finding the most accurate formula available. I understand how to estimate ballpark.
For example, I know that you can get a ballpark estimate using something like:
((1 - (attenuation% * 0.01 )) * GravityPoints)
but my question is this:
1: technically, this calculation won't allow for a FG lower than 1.000. I know that is rare, but it does happen.
2: Does adjuncts like dextrose need to be calculated separately (with a different attenuation %) and then combined after?
3: I've done a ton of reading on adjusting FG from mash temp. I know beersmith has a slope that you can adjust. Anyone have any other methods?
Hopefully others out there like to geek out on formulas and calculations and can point me in the right direction.
Cheers.
