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.
Red Wine Styles
Red wines are made into a variety of styles. The stylistic differences are based on differences in wine characteristics such as grape variety, color, flavor, body, mouthfeel, and aging potential. The styles range from simple, fruity, fresh, lightcolored blushes and rosés to complex, full-bodied, rich and darkred, with long aging potential. Many factors such as a variety, soil, climate, growing conditions, and viticultural practices influence the fruit composition, and therefore, the style of wine that can be produced.
In addition to fruit composition, winemaking techniques also play an important role in determining the wine style.

Generally the fruit is harvested based on sugar (ºBrix), titratable acidity, and pH. It should be noted that for making red wine, following only these harvest criteria is not sufficient.
