Ethanol fermentation, also called alcoholic fermentation, is a biological process which converts sugars such as glucose, fructose, and sucrose into cellular energy, producing ethanol and carbon dioxide as by-products. Because yeasts perform this conversion in the absence of oxygen, alcoholic fermentation is considered an anaerobic process.
Bottle fermentation is a method of sparkling wine production, originating in the Champagne region where after the cuvee has gone through a primary yeast fermentation the wine is then bottled and goes through a secondary fermentation where sugar and additional yeast known as liqueur de tirage is added to the wine. This secondary fermentation is ...
Fermentation usually implies that the action of microorganisms is desired. The science of fermentation is known as zymology or zymurgy. The term "fermentation" sometimes refers specifically to the chemical conversion of sugars into ethanol, producing alcoholic drinks such as wine, beer, and cider.
Tibicos water crystals made with Muscovado. This is a list of fermented foods, which are foods produced or preserved by the action of microorganisms.In this context, fermentation typically refers to the fermentation of sugar to alcohol using yeast, but other fermentation processes involve the use of bacteria such as lactobacillus, including the making of foods such as yogurt and sauerkraut.
In ethanol fermentation, one glucose molecule is converted into two ethanol molecules and two carbon dioxide (CO 2) molecules. [10] [11] It is used to make bread dough rise: the carbon dioxide forms bubbles, expanding the dough into a foam. [12] [13] The ethanol is the intoxicating agent in alcoholic beverages such as wine, beer and liquor. [14]
The process of fermentation at work on Pinot noir. As yeast consume the sugar in the must it releases alcohol and carbon dioxide (seen here as the foaming bubbles) as byproducts. The role of yeast in winemaking is the most important element that distinguishes wine from fruit juice.
Kombucha mother is created from the fermentation of tea, while Mother of vinegar is created from the fermentation of wine, cider, or other alcoholic beverages. The fermentation process of tea creates SCOBY. The SCOBY creates a bacterial cellulose film, like that seen in mother of vinegar. The bacteria also oxidizes the alcohol to create acetic ...
Some yeasts can produce 18% alcohol in the wine however extra sugar is added to produce a high alcohol content. During or after the alcoholic fermentation, a secondary, or malolactic fermentation can also take place, during which specific strains of bacteria (lactobacter) convert malic acid into the milder lactic acid. This fermentation is ...
