2. Fermentation in winemaking - Wikipedia

   en.wikipedia.org/wiki/Fermentation_in_winemaking

   The process of fermentation in winemaking turns grape juice into an alcoholic beverage. During fermentation, yeasts transform sugars present in the juice into ethanol and carbon dioxide (as a by-product). In winemaking, the temperature and speed of fermentation are important considerations as well as the levels of oxygen present in the must at ...

3. Yeast in winemaking - Wikipedia

   en.wikipedia.org/wiki/Yeast_in_winemaking

   The role of yeast in winemaking is the most important element that distinguishes wine from fruit juice. In the absence of oxygen, yeast converts the sugars of the fruit into alcohol and carbon dioxide through the process of fermentation. [1] The more sugars in the grapes, the higher the potential alcohol level of the wine if the yeast are ...

5. Gravity (alcoholic beverage) - Wikipedia

   en.wikipedia.org/wiki/Gravity_(alcoholic_beverage)

   Gravity, in the context of fermenting alcoholic beverages, refers to the specific gravity (abbreviated SG), or relative density compared to water, of the wort or must at various stages in the fermentation. The concept is used in the brewing and wine-making industries. Specific gravity is measured by a hydrometer, refractometer, pycnometer or ...

6. Malolactic fermentation - Wikipedia

   en.wikipedia.org/wiki/Malolactic_fermentation

   Chemically, malolactic fermentation is a decarboxylation, which means carbon dioxide is liberated in the process. [2][3] The primary function of all these bacteria is to convert L-malic acid, one of the two major grape acids found in wine, to another type of acid, L+ lactic acid. This can occur naturally. However, in commercial winemaking ...
