Home winemakers take a variety of measurements as they make and condition their wine. From the sugar content of grapes to the specific gravity of fermenting wine to the volume in a tank, accurate information helps improve the quality of the finished product. However, if you haven’t calibrated your measuring devices, all these measurements could be off.
