The HI96811 Digital Wine Refractometer converts the refractive index of a wine, juice or must sample to % Brix. This conversion is based on the tables found in the ICUMSA Methods Book (International Commission for Uniform Methods of Sugar Analysis) that documents the changes in refractive index with temperature for a percent by weight sucrose solution. Since the majority of sugar in grape juice and must is fructose and glucose instead of sucrose, the reading is sometimes referred to as “Apparent Brix”. Typical grapes at harvest will be between 19-24% Brix or degrees Brix (°Bx). The HI96811 is an easy-to-use tool for winemakers for measuring sugar in grapes or must, in the field or in the lab.
