Primary fermentation usually takes between three to seven days to complete. It goes by much more quickly than secondary fermentation because wine must is a much more fertile environment for the yeast. Sugar and oxygen levels are high during primary fermentation and there are plenty of nutrients.
The basic procedure of red wine production is outlined in the diagram. An important point in making red wine is that the fermenting must consists of juice skins and seeds. As a result, the composition of red wine is determined by the constituents extracted from skins and seeds in addition to those present in the juice.his fermentation is caused by the cellâs own enzymes, (without yeast). The fermentation produces a small amount of alcohol (about 1.5 to 2.5%), and brings about many changes in the must composition. The fermentation is carried out for about eight to ten days. The temperature is held near 95 ÂºF.
