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 ...
It is fitted with a fermentation lock. A fermentation lock or fermentation airlock is a device used in beer brewing and wine making that allows carbon dioxide released during fermentation to escape the fermenter, while not allowing air to enter the fermenter, thus avoiding oxidation. There are two main designs for the fermentation lock.
This secondary fermentation, also known as bottle fermentation, is the process that makes the wine "bubbly" due to the containment of carbon dioxide which is normally released as a by product in regular fermentation. In still wine production, particularly of red wines [2] and some white wines like Chardonnay, the secondary fermentation process ...
During the secondary fermentation and aging process, which takes three to six months, the fermentation continues very slowly. The wine is kept under an airlock to protect the wine from oxidation. Proteins from the grape are broken down and the remaining yeast cells and other fine particles from the grapes are allowed to settle.
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 convert sugar into ...
Kilju in its fifth day of fermentation. An air lock has been added to keep unnecessary and harmful bacteria away from the fermenting beverage. The process is similar to that of homebrewing wine. If done slowly, it requires rigorous hygiene and filtering of the product.
During fermentation, the added oxygen can help maintain the viability of the yeast to minimize the risk of stuck fermentation and the production of undesirable sulfides. After fermentation it can aid in the clarification and stabilization of the wine without resorting to the use of fining agents .
Fully fermented A wine that was allowed to complete the process of fermentation without interruption to produce a wine that is completely dry. Fusel alcohol Also known as Fusel oils. By-products of fermentation and distillation that are encountered in small quantities in winemaking that can contribute to a wine's complexity.
