Several weeks ago I was brewing with someone and we used my refractometer to check the pre & post boil gravity. Both were 15.5.
We thought this a bit odd but chalked it up to "maybe we didn't mix the wort enough" or "maybe we just mis-read the thing."
Today, I brewed again, my pre-boil gravity (temp about 150F) was 11.4 (target was 15.3) and my post-boil was 11.4 (chilled wort) as well. I stirred the pot and checked the pot-boil several times with identical results.
The refract is an auto-temp adjust and I calibrated it today before I used it.
I never saw this kind of thing with the hydrometer. (Next time I will use the hydrometer AND the refract ... )
Does anyone have any ideas on what might be causing this?
