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 ...
Maceration (wine), a step in wine-making Carbonic maceration, a wine-making technique; Maceration (sewage), in sewage treatment; Maceration (bone), a method of preparing bones; Acid maceration, the use of an acid to extract micro-fossils from rock; Maceration, in chemistry, the preparation of an extract by solvent extraction
Maceration continues during the fermentation period, and can last well past the point when the yeast has converted all sugars into alcohol. The process itself is a slow one with compounds such as the anthocyanins needing to pass through the cell membrane of the skins to come into contact with the wine.
All production methods for sparkling wines have one thing in common: the purpose of introducing enough carbon dioxide in the wine to make it effervescent. Champagne bottles in racks in underground cellars
Agiorgitiko is a very versatile grape variety that can be made in a wide range of styles from light rosés to soft, fruity reds made by carbonic maceration in a style similar to the French wines of Beaujolais, to very tannic wines with spicy, red fruit aromas and the potential to age.
In red wine production, the maceration process was traditionally done in large vats where the fermentation process would begin (in the picture this is noted by the presence of carbon dioxide bubbles). Secondary fermentation would take place when the wine is transferred to a second container such as a carboy or oak barrel.
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.
