Just on my 3rd brew and I'm still having some difficulty with mash eficiency and volumes. I have Beersmith which has helped me out of a few fixes, and Screwtop and Bindy have been great too. Anyway, a question. In Beersmith is the Estimated original gravity, the gravity of the wort before or after the boil? If its after, and say I am looking for a SG of 1047, what should be the rough SG, preboil.
