The mass difference between equivalent volumes of must and water is almost entirely due to the dissolved sugar in the must. Since the alcohol in wine is produced by fermentation of the sugar, the Oechsle scale is used to predict the maximal possible alcohol content of the finished wine. This measure is commonly used to select when to harvest ...
A relative density saccharometer in a sugar solution, 1040 g/L. Baumé scale (Bé°): Occasionally used in France and by U.S. brewers. Oechsle scale (°Oe): Used in Germany, Luxemburg and Switzerland. It is an important part of the German wine classification. Relative density: Used in the United States (although Brix is sometimes used).
The natural occurrence of fermentation means it was probably first observed long ago by humans. [3] The earliest uses of the word "fermentation" in relation to winemaking was in reference to the apparent "boiling" within the must that came from the anaerobic reaction of the yeast to the sugars in the grape juice and the release of carbon dioxide.

The concept is used in the brewing and wine-making industries. Specific gravity is measured by a hydrometer, refractometer, pycnometer or oscillating U-tube electronic meter. The density of a wort is largely dependent on the sugar content of the wort. During alcohol fermentation, yeast converts sugars into carbon dioxide and alcohol. By ...
Dry bulk ingredients, such as sugar and flour, are measured by weight in most of the world ("250 g flour"), and by volume in North America ("1 ⁄ 2 cup flour"). Small quantities of salt and spices are generally measured by volume worldwide, as few households have sufficiently precise balances to measure by weight.
Just as people use sugar or salt when making preserved foods, sugar is also a preservative for wine. [4] The sugar lowers the water activity of the food, meaning that less water is available for the bacteria, stunting its growth. [2] Salt is used as a preservative in the same way. [8]
