I brewed an all grain pumpkin ale this weekend and had some issues measuring the extraction gravity. After pouring the wort into the boil kettle, I pulled a sample into a glass to let it cool before taking a hydrometer reading. When the sample had cooled to approximately 75-80 degrees, I testing the sample with my hydrometer and got 1.042. Because I had plenty of wort left to do a second check later, I set the glass inside and let the wort cool further. A second read (about two hours later) was 1.036. Why would I get a different reading from the same sample, the only difference is letting it sit and cool another 5-10 degrees? (A later reading from a refractometer was 11 Brix, which translates to 1.044)
I used the same hydrometer for both readings and same source sample for all three readings (2 hydro, 1 refrac)
