I brewed an Irish Amber which BeerSmith told me should have an OG of 1.54 (right where the recipe said it would be). I used a refractometer to get a gravity reading from the wort before adding water, then used b.s.'s dilution tool to figure out my OG. 1.53. So far so good. I then added, accidently, 1/2 gallon too much water to the fermenter, and also got less than I should have out of the kettle, which, using the various b.s. calculations, should have put my gravity down to 1.46. I took a refractometer reading of the cooled and mixed wort and it came out to 1.43 (using the b.s. tool). Again, ok. When the wort finished fermenting, I degassed the sample, and took a refractometer and hydrometer reading. Using the B.S. tool for determining OG from a hydrometer and refractometer, it gave me a calculated OG of.....1.54. Also, the hydrometer showed a FG of 1.013 (corrected for temperature), and the refractometer (again, using the b.s. tool for fermented wort) showed a FG of 1.008. What gives? Which OG reading should I trust?
