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.
The wine goes into bottle, sealed under a crown cap, where the still viable yeast, nutrient and sugar allow the primary fermentation to continue and produce the carbon dioxide that forms the bubbles. Malolactic fermentation may also occur in bottle making a small contribution to the carbon dioxide levels.
When the base wine (or cuvee) has been produced from single grape varietals or a blend, the wine is bottled with a mixture of yeast and fresh sugar known as the "liqueur de tirage". 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 ...
The transfer method is used to make small and large format bottles of sparkling wine, such as this split (quarter bottle) of champagne. There are several methods used to carry out this secondary fermentation. The most well known is the traditional or "champagne method" where the base cuvée is bottled with a mixture of sugar and yeast. The ...
In contrast to tartaric acid, if the grapes are too acidic, calcium carbonate is used to bring them down to the level needed to make wine. [10] In addition, many also use oak, oak slices, fermentation agents, tutu, and more, according to the quality of grapes and the different styles of wine.
