the name of a density scale for measuring sugar content in water solutions. Since grape juice is primarily sugar and water, the balling scale was used for a quick and easy "sugar analysis" of juice. The original Balling scale contained a slight inaccuracy however. Dr Brix discovered that and corrected it. Today the Brix scale is in actual use, but the terms Balling and Brix often are spoken of as if they were identical. The Balling (Brix) scale is simplicity itself: Each degree is equivalent to 1 percent of sugar in the juice. For example, grape juice that measures 15.5 degrees on the Balling or Brix scale contains approximately 15.5% sugar. richardgrantwine.com
