kleclerc77 Posted July 13, 2018 Share Posted July 13, 2018 While proofing down some potato vodka, there was a big difference in what I calculated versus what the hydrometer was reading. It should have ended up at 80 proof, but the hydrometer was reading 92 proof. Adjusting for temperature (85°) according to the chart that came with the hydrometer, I subtracted .4 to end up with roughly 91.6 proof. Baffled, I checked the HoochWare app to see what it said the true proof at the temperature is, which said 80 proof. It gave me some confidence that I didn't do my math wrong, but left me confused about temperature adjustment. TLDR: what is the best way to adjust for true proof when the temperature isn't reading 60°? Link to comment Share on other sites More sharing options...
