I could have sworn I saw something to calculate the FG of my brew but for the life of me I can't find where I read it.

Is there a strait forward way of calculating the FG and final alcohol content of your brew?

(og-fg) x 131 = ABV

Perfect, now how do I estimate the expected FG?

You can measure the FG with a hydrometer.

Or, if you want to estimate it, you can use Beersmith, or Promash, or a free online one like: http://beercalculus.hopville.com/recipe

EDIT: Damn Doug, you beat me to it!

Promash doesn't estimate the FG. It assumes the FG is 1.012, and allows you to plug in the real value when you know what it is.
Beersmith does estimate the FG, but for the way that I brew, the estimates are at least 5 points higher than I regularly achieve.
You cannot rely on FG's predicted by software unless you have verified that the software predictions consistently match your own results.

ajf, with that in mind, do you think this sort of software can still be useful for designing recipes? At least a starting point for a first attempt?
