Is there a function on Fermcalc that adjusts SG to the temperature of the must? We are usually at room temp but are now putting cider in a low temp cooler. WVMJ
Go to "Alcohol" then "Hydrometer SG Drop", or "Hydrometer & Refractometer". There you'll input your SG readings and temps, along with the calibration temp of your hydrometer, and the cooected value will show.
