Additional Notes:

Refractometer was low by maybe 5 brix during brew day. Found out later refractometers change their reading based on temperature, and it was cold out. So the OG is probably less than 1.084. Probably more like 1.068.

The final gravity of 1.003 was taken at room temperature. This is too low. I'm confused.
