White and red wine. The berries of the grape , which is the raw material of wine, sugars , organic acids and water (over 70 %). The content of these substances depends each time on the variety, the subsoil , the climatic conditions, but also on the timing of maturation of the grape. After the process of harvesting ( harvesting ), followed by glefkopoiisi the procedure during which exports must (or must usually ) from the grape . For the extraction of grape used various methods , usually by using special equipment operating crushing grapes between rollers . In glefkopoiisi , it should remove the stems ( apovostrychosi ) grape , as it is detrimental to both the flavor of the final wine , and for the health of the consumer. Variety of black grape Then follows the final fermentation process . Alcohol containing wine produced from the wort sugars by reacting the alcoholic fermentation is performed by specific enzymes , the zymases yeast . The yeasts are inactivated in the skin of grapes , and as they come into contact with the must, proliferate and perform the fermentation . Besides ethyl alcohol is produced and carbon dioxide but also a number of secondary products and compounds that are key many times for the quality of the wine. The fermentation process typically takes 8-25 days. It is customary , be extended or interrupted fermentation by artificial means , in particular by maintaining the temperature at low or high respectively. The time of fermentation is crucial for the wine to be produced eventually. Addition is usually reason for white and red wine , depending on the color of the wine produced . Of particular value is the end and the aging process of wine. It is generally considered that a wine gets better as ages , but different types of wine characterized by different life . Furthermore a wine may undergo and aging, and so should not be consumed . Main objective is to practice slow and controlled oxidation of the wine. The duration of the maturation and usually varies from a few months to a few years . General minimum wines have a shelf life of over 50 or 100 years , with most arriving in qualitative climax within a few years.
