Enology & Winemaking

In enology and winemaking, the MA885 Digital Refractometer plays a crucial role in monitoring the sugar content of grapes, must (the crushed grape juice, skins, seeds, and stems), and wine during the fermentation process. The sugar content, typically measured in Brix, directly influences the fermentation process and the final alcohol content in the wine.

Before fermentation begins, winemakers use the MA885 to measure the sugar concentration in grapes to assess their ripeness. This helps them decide the optimal harvest time, ensuring the grapes have reached the desired level of sugar for the style of wine they want to produce. The refractometer provides a precise Brix reading, allowing winemakers to track the sugar levels in different batches of grapes and select the best grapes for winemaking.

Once the grapes are crushed and the must is prepared, the MA885 is used to measure the sugar content in the must. This is essential for determining how much sugar is available for fermentation and predicting the potential alcohol content in the finished wine. The refractometer’s accuracy ensures that winemakers can monitor this critical stage and make adjustments if needed, such as adding more sugar or diluting the must.

During fermentation, the MA885 is also used to track the sugar depletion, as yeast consumes the sugar to produce alcohol. By regularly measuring the Brix, winemakers can determine when the fermentation process is nearing completion and make timely decisions about stopping fermentation, such as through cooling or filtering, if necessary.

In addition to Brix, the MA885 provides readings in °Oechsle and °KMW, which are specific to enology. These units help wine professionals in different regions measure and assess the quality and potential alcohol content of the wine. The °Oechsle scale is commonly used in Germany and Switzerland, while the °KMW scale is popular in France.

In short, the MA885 refractometer provides precise and fast sugar content measurements throughout the winemaking process, helping winemakers ensure consistent quality and control over the fermentation process and the final product.
