I have been averaging about 84% efficiency for my AG batches, according to my hydrometer readings. I bought a refractometer this week, and to calibrate it, bought a gallon of distilled H2O. I figured, let me check my hydrometer calibration while I'm at it. 60F distilled H2o...1.004!!! Not cool. Oh well. Hope my refractometer works out better.
