Determination of the sugar content and Oechsle value of grapes

Determination of the sugar content and Oechsle value of grapes

A refractometer is an optical measuring instrument used by winemakers to determine the sugar content (Brix) and the expected alcohol content (Oechsle). The sugar content in wine grapes increases as they ripen. Winemakers can use the refractometer to monitor the ripeness of the grapes and determine the optimal time for harvesting. By converting the measured sugar content, the winemaker can estimate the potential alcohol content of the future wine.

By checking and measuring the Brix value (sugar) and Oechsle value (expected alcohol content) using a refractometer, it is ensured that the taste and alcohol content of the wine is consistent. In addition, the refractometer is a helpful measuring instrument to determine the correct degree of ripeness of the grapes and thus the optimal time for the grape harvest!
