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 ...
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 ...

Acetic acid is a two- carbon organic acid produced in wine during or after the fermentation period. It is the most volatile of the primary acids associated with wine and is responsible for the sour taste of vinegar. During fermentation, activity by yeast cells naturally produces a small amount of acetic acid.

Acetic acid bacteria ( AAB) are a group of Gram-negative bacteria which oxidize sugars or ethanol and produce acetic acid during fermentation. [ 1] The acetic acid bacteria consist of 10 genera in the family Acetobacteraceae. [ 1] Several species of acetic acid bacteria are used in industry for production of certain foods and chemicals.
v. t. e. Anatomy (from Ancient Greek ἀνατομή (anatomḗ) ' dissection ') is the branch of morphology concerned with the study of the internal structure of organisms and their parts. [ 1] Anatomy is a branch of natural science that deals with the structural organization of living things. It is an old science, having its beginnings in ...
Carbonic maceration. Carbonic maceration is a winemaking technique, often associated with the French wine region of Beaujolais, in which whole grapes are fermented in a carbon dioxide rich environment before crushing. Conventional alcoholic fermentation involves crushing the grapes to free the juice and pulp from the skin with yeast serving to ...
