I'm finishing up my sparge and took a hydrometer reading in both the brew kettle and in a hydrometer vial. The temp in the kettle is currently 118 and change and when you put it in the hydrometer vial drops right down to 109 and change. The mystery is when I take the reading right in the kettle its 1.042 but in the vial its 1.032 which even after correction is a pretty big difference. Thoughts?
