I have been incredibly frustrated my last few brews, because my efficiency comes out to around 50%. I have been using Beersmith for my calculations.
On a whim, I downloaded Beer Alchemy and put in the recipe I did last night that I missed by 9 gravity points. At 65% efficiency (which I had resigned myself to because of constantly missing my mark), the BS2 version says my OG should be 1.060, but BA says 1.047. I have the same pre boil and post boil and final volumes for both.
I have included screen shots of the two recipes.
What is happening here? I feel like I am going crazy, and that if I just use BA, then my recipes and efficiencies are going to be correct.
