The natural occurrence of fermentation means it was probably first observed long ago by humans. [3] The earliest uses of the word "fermentation" in relation to winemaking was in reference to the apparent "boiling" within the must that came from the anaerobic reaction of the yeast to the sugars in the grape juice and the release of carbon dioxide.
This intracellular fermentation (as opposed to the traditional extracellular fermentation of wine yeast) tends to produce fruity, deeply colored red wines with low tannins Casein A fining agent derived from a milk protein. Cask A wood barrel or storage vessel, often made from oak, that is used in winemaking for fermentation and/or aging Cask ...
Barrel aging is a process used to add maturity and character and additional flavour to a beer. Beers are aged for a period of time in a wooden barrel. Typically, these barrels once housed wine, rum, whiskey, bourbon, tequila, and other wines and spirits. Beers are sometimes aged in barrels to achieve a variety of effects in the final product.
Oak wine barrels. Oak is used in winemaking to vary the color, flavor, tannin profile and texture of wine. It can be introduced in the form of a barrel during the fermentation or aging periods, or as free-floating chips or staves added to wine fermented in a vessel like stainless steel.
The secondary fermentation usually takes place in large stainless steel vessels with a volume of several cubic meters, oak barrels or glass demijohns (also referred to as carboys), depending on the goals of the winemakers. Unoaked wine is fermented in a barrel made of stainless steel or other material having no influence on the final taste of ...
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.
A wood barrel or storage vessel, often made from oak, that is used in winemaking for fermentation and/or aging Casta Portuguese term for a grape variety Caudalie Unit of the persistence of the wine's finish in seconds. Derived from the word caudal (tail). A wine can have a caudalie of 8 or more seconds. [4] Cava
Secondary fermentation is a process commonly associated with winemaking, [1] which entails a second period of fermentation in a different vessel than the one used to start the fermentation process. An example of this would be starting fermentation in a carboy or stainless steel tank and then moving it over to oak barrels. Rather than being a ...
