Description
The HI96814 Digital Wine Refractometer converts the refractive index of wine juice or must to sucrose concentration in units of percent by weight, % Brix (also referred to as °Brix). The conversion used is based on the ICUMSA Methods Book (International Commission for Uniform Methods of Sugar Analysis). Since the majority of sugar in grape juice is fructose and glucose and not sucrose, the reading is sometimes referred to as “Apparent Brix”.
In addition to % Brix, HI96814 includes two other scales used in the wine industry: °Oechsle and °KMW.
°Oechsle (°Oe) is mainly used in the German, Swiss and Luxembourgish winemaking industry to measure the sugar content of must. The °Oe scale is based on specific gravity at 20°C ((S.G.(20/20)) and is the first 3 digits following the decimal point. One °Oe is roughly equal to 0.2 % Brix.
°Oe = [(S.G.(20/20)) – 1] x 1000
°Klosterneuburger Mostwaage (°KMW) is used in Austria to measure the sugar content of must. °KMW is related to °Oe by the following equation: °Oe = °KMW x [(0.022 x °KMW) + 4.54] 1 °KMW is roughly equivalent to 1% Brix or 5 °Oe. °KMW is also known as °Babo.
“Potential” or “probable” alcohol is an estimation of the alcohol content (% vol/vol) in finished wine based on the conversion between sugar and alcohol. This conversion depends on many factors, such as the type of grapes, the grape maturity, the growing region and yeast fermentation efficiency and temperature.
The HI96814 is an easy to use tool for winemakers for measuring sugar in grapes or must, in the field or in the lab.
