Brewed the recipe listed below. Brew day went great. Hit my temps and volumes, but I am thrown off by my gravity readings. I did just get a new refractometer and calibrated it with distilled water. See readings below.
Pre-boil volume: 8.9 Gal
Pre-boil Gravity: 1.048
Post boil Volume: 5.5 Gal (1.5 hour boil)
Post boil Gravity (OG): 1.054
I calculated 87% efficiency. So with that known and my final volume of 5.5 Gal I should have been at 1.078 OG. Any ideas how I got 1.054 on my refractometer? It has ATC and should have been cool enough while checking. I am currently at 1.007 after 7 days of fermantation. I just want to know what the ABV will be and what I did wrong.
