I found this site: http://onebeer.net/refractometer.shtml
It says it does the math to convert same-temp/accurate brix measurements from a refractometer to gravity readings.
I am (and have been) using a refractometer to avoid beer waste. A few drops >> filling a hydrometer.
My question is, is this site accurate? I frequently get a starting brix around 15-17, and my finals are around 5-8. That would indicate some seriously high alcohol by volumes using this calculator. Not that I mind at all, just wondering if the calculations on the above site are correct for 68°F wort measurements.
