Carbonic maceration techniques (e.g. semi-carbonic maceration) have recently been adapted to coffee processing. The ripe coffee cherries are placed inside a hermetic stainless steel tank and left to undergo an anaerobic fermentation. This fermentation process brings out intense aromas, with a taste profile akin to red wine and whisky.
Carbonic maceration is the fermentation of whole clusters of unbroken grapes in an atmosphere saturated with carbon dioxide, which prevents traditional yeast fermentation. It is a process different from what is commonly referred to in winemaking as "maceration".
Carbonic maceration [ edit ] The process of carbonic maceration is also known as whole grape fermentation where instead of yeast being added, the grapes fermentation is encouraged to take place inside the individual grape berries.
Vino novello is made from a different process to normal red wines. Novello is the result of a different procedure of processing the grapes, carbonic maceration, which involves accelerating the fermentation process. This method was developed in France in the 1930s.

Carbonic acid Carbon dioxide gas dissolved in the water content of wine. It is a volatile acid that held in equilibrium with the dissolved carbon dioxide gas and can not be isolated in a pure form. Carbonic gas A natural by product of the fermentation process in which yeast cells convert sugar into nearly equal parts alcohol and carbonic gas ...
The acidity is softened through carbonic maceration, a process that also allows the vibrant youthful fruit expressions reminiscent of bright crushed strawberries and raspberries, as well as deep floral notes of lilac and violets. Gamay-based wines are typically light bodied and fruity.
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.
