The history of wine -making stretches over millennia.
The process of fermentation in winemaking turns grape juice into an alcoholic beverage. During fermentation, yeasts transform sugars present in the juice into ethanol and carbon dioxide (as a by-product). In winemaking, the temperature and speed of fermentation are important considerations as well as the levels of oxygen present in the must at ...
History of wine. Hellenistic mosaics discovered close to the city of Paphos depicting Dionysos, god of wine. Wine boy at a Greek symposium. The oldest evidence of ancient wine production has been found in Georgia from c. 6000 BC (the earliest known traces of grape wine), [1][2][3][4] Iran from c. 5000 BC, [5] Greece from c. 4500 BC, [6][7 ...
Wine is an alcoholic drink made from fermented fruit. Yeast consumes the sugar in the fruit and converts it to ethanol and carbon dioxide, releasing heat in the process. Wine is most often made from grapes, and the term "wine" generally refers to grape wine when used without any qualification. Even so, wine can be made from a variety of fruit ...

Wine production in 2014 [1] Wines are produced in significant growing regions where vineyards are planted. Wine grapes mostly grow between the 30th and the 50th degree of latitude, in both the Northern and Southern Hemispheres, typically in regions of Mediterranean climate. Grapes will sometimes grow beyond this range, thus minor amounts of ...
Yeast in winemaking. The process of fermentation at work on Pinot noir. As yeast consume the sugar in the must it releases alcohol and carbon dioxide (seen here as the foaming bubbles) as byproducts. The role of yeast in winemaking is the most important element that distinguishes wine from fruit juice. In the absence of oxygen, yeast converts ...
In winemaking, clarification and stabilization are the processes by which insoluble matter suspended in the wine is removed before bottling. This matter may include dead yeast cells (lees), bacteria, tartrates, proteins, pectins, various tannins and other phenolic compounds, as well as pieces of grape skin, pulp, stems and gums. [1]
