So I have a batch fermenting that I forgot to grab an OG reading for, and I couldn't be bothered to open it back up and take the reading initially. However, when I pulled a sample today, I thought of something. I have both a refractometer and hydrometer, so I took a reading with both. The refractometer read about 7.1, and the hydrometer read 1.018. With the calculation to compensate for the presence of alcohol, and knowing what the actual gravity reading is, would it not make sense that I can then basically 'triangulate' to find the right OG to fit the equation? I estimated that my original Brix was about 11.5 or 11.6, meaning somewhere around 1.047 for my OG.
I used the morebeer refractometer spreadsheet tool to figure this out by just changing numbers until everything lined up.
Anyone have any reason to refute this estimate?
