So, after my first AG batch I would like to know what my efficiency was. I tried running the numbers myself and I must be wrong.

2-Row Malt 9lbs
carafoam 0.5lb
OG about 1.058

I came up with 80%, is that right?

One critical piece of information missing here.. how much (volume) did you end with??

Could also do a quick double-check w/ this website: http://www.brewersfriend.com/brewhouse-efficiency/

No worries. When I do the calc I get 74.7% efficiency - (58x4.5)/(9x37+0.5x33)

Matches pretty well with the online calc I noted above (74.25%).. depends a bit on what source you look at for each grains ppg.. varies a bit.
