The duration of maceration for red wine varies from a few days to several weeks, depending on the final result that the winemaker wants to get.Īfter fermentation and maceration (parallel processes in one tank) we transfer all the material to the press. Fermentation - (the art & science of turning fruit juice into wine) - is basically the conversion of grape sugars into nearly equal parts of alcohol and CO2 by. Thus, without maceration, we would not be able to produce a truly red colored wine. During these processes, the sugar contained in the grape juice is converted by yeasts enzymes into ethyl alcohol and carbon dioxide. The fact is that most red grapes have a transparent pulp, and the components responsible for color are in the skin. Maceration is a process during which the skin is in contact with grape juice (the berries are partially crushed, so we already have both solid materials and liquid in the container) to extract color, aromas, tannins and other components. Maceration is one of the main differences between the white and red wine production. And in parallel there is a process of maceration. (For example, the distillation of beer wort creates whiskey, while the distillation of wine produces brandy.) All alcoholic beverages undergo fermentation, thought not. Distillation is a process used to higher-ABV beverages from already-fermented base products. For the production of white wine we get rid of the skin as soon as possible, then for the production of red – we still need skins.įermentation starts. Alcoholic fermentation is the process of using yeasts to convert sugars into alcohol. Fermentation processes to produce wines are traditionally carried out with Saccharomyces cerevisiae strains, the most common and commercially available yeast, and some lactic acid bacteria. Berries separated from the stems are placed in a large container. For red wine, things are a bit different.
