Whole-cluster pressing is where instead of first sending the grapes through a destemmer/crusher the intact grapes are directly pressed still attached to the stems. This is a method that is widely used for white, rosé and sparkling wine production because it usually produces a more delicate, less phenolic and less colored wine.
A winemaking practice of fermenting whole grapes that have not been crushed. 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.

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 ...
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.
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.
There are exceptions, such as the case of sparkling wine production in regions such as Champagne, where grapes are traditionally whole-cluster pressed with stems included to produce a lighter must that is low in phenolics. [3] In white wine production, pressing usually takes place immediately after crushing and before primary fermentation.
French term, meaning vat or tank. On wine labels it is used to denote wine of a specific blend or batch. Cuverie French term, along with cuvier that refers to the building or room where fermentation takes place. Essentially, the room, building, grange, barn, garage or shed, or other building, used for "making wine."
Grape cluster architecture. The placement of a cluster on the vine is similar to that of a tendril, [3] as both develop from the same uncommitted primordia, the anlagen. The grape bunch position on the side of the stem opposing a leaf is unusual for inflorescence of the plants. [2] The typical shape of a cluster depends on the grape variety. [4]
