I measured the FG with my refractometer on some hefeweizen and freaked out. Then I remembered that the readings had to be compensated for the alcohol. Denny, that is a fantastic method. Just out of curiosity, couldn't you have re-calibrated the hydrometer using some distilled water? I know mine has an adjustment knob just for that purpose. Cheers,Rich
Do you measure final gravity?

I assume you mean refractometer, Rich. I tried that many times in many different ways. I tried calibrating it to my hydrometer, even, but it was off the next reading I took. Being the pragmatic type, i figured that I had a cocktail shaker I didn't use....Denny, that is a fantastic method.

Must have been dropped or maybe the surface had been contaminated and gave false readings.I like the way you came up with using the shaker.Cheers,RichI assume you mean refractometer, Rich.
