So after my mash/sparge is done I take a reading with my refractometer and see that I've reached my estimated pre-boil gravity of 1.050 right on the nose. I then boiled for 90 minutes adding my hops at 60, 15, and 5. Before cooling with my chiller I take another reading with my refractometer and notice I that I am much lower then the expected original gravity. Just curious exactly why this is? Is it something to do with the boiling process?
