The primary fermentation process where yeast and sugars react to produce alcohol and also the first step in turning grape juice into wine.
The action of yeast upon sugar results in its conversion to ethyl alcohol, with carbon dioxide as a by-product. Fermentation will often start naturally with yeasts on the grapes, but cultured yeasts may be added. The process generates much heat, and temperature control during alcoholic fermentation can have a significant effect on the style of wine produced. The process will cease either when all the sugar has been consumed, or more likely when the increasing alcohol content of the fermenting solution kills the yeast, or when the external temperature drops too low. It may also be arrested by adding sulphur or by fortification with spirit.

conversion of sugar to alcohol + CO2 + heat by the action of yeasts. The process by which grape juice becomes wine.
it is the fulcrum of the whole world liqueur production. It deals with a complex biochemical process that turns the various musts containing sugars into alcohol. All products that can produce sugars in the vegetable world: cereals = starches = (for fission) sugars; fruit, that already contain sugars; juicy plants (ex. agave), etc.. have been and are still used for the alcoholic fermentation. The basic process is: Sugars + yeasts = Alcohol + carbonic anhydride.+ energy. In nature, the process that develops this is much ampler and develops the formation of various types of alcohol (the amino acids present are turned into superior alcohol that modifies the taste) and other substances.
The process by which yeast turns sugar into carbon dioxide (CO2) and alcohol. In most fermentations, the CO2 is allowed to evaporate, but in Methode Champenoise fermentations used to make Champagne and other sparkling wines, the CO2 is captured under pressure and becomes the bubbles in the bottle.
Process by which sugars in the must are transformed into ethyl alcohol using yeasts.

the conversion of sugar into alcohol and carbon dioxide in the presence of yeast. Wine character is largely formed during this process.
