Viticulture

Viticulture (from the Latin word for vine) or winegrowing (wine growing) is the cultivation and harvesting of grapes. It is a branch of the science of horticulture. While the native territory of Vitis vinifera, the common grape vine, ranges from Western Europe to the Persian shores of the Caspian Sea, the vine has demonstrated high levels of adaptability to new environments. Thus, viticulture can be found on every continent except Antarctica. Viticulture (from the Latin word for vine) or winegrowing (wine growing) is the cultivation and harvesting of grapes.

Thus, viticulture can be found on every continent except Antarctica. Duties of the viticulturist include monitoring and controlling pests and diseases, fertilizing, irrigation, canopy management, monitoring fruit development and characteristics, deciding when to harvest, and vine pruning during the winter months. Viticulturists are often intimately involved with winemakers, because vineyard management and the resulting grape characteristics provide the basis from which winemaking can begin.A great number of varieties are now approved in the European Union as true grapes for winegrowing and viticulture. The earliest evidence of grape vine cultivation and winemaking dates back 7,000 years. The history of viticulture is closely related to the history of wine, with evidence that humans cultivated wild grapes to make wine as far back as the Neolithic period. Evidence suggests that some of the earliest domestication of Vitis vinifera occurred in the area of the modern countries Georgia and Armenia. The oldest-known winery was discovered in the 'Areni-1' cave in Vayots Dzor, Armenia. Dated to c. 4100 BC, the site contained a wine press, fermentation vats, jars, and cups. Archaeologists also found V. vinifera seeds and vines. Commenting on the importance of the find, McGovern said, 'The fact that winemaking was already so well developed in 4000 BC suggests that the technology probably goes back much earlier.' There is also evidence of grape domestication in the Near East in the early Bronze Age, around 3200 BC. Evidence of ancient viticulture is provided by cuneiform sources (ancient writing on clay tablets), plant remains, historical geography, and archaeological excavations. The remnants of ancient wine jars have been used to determine the culture of wine consumption and cultivated grape species. In addition to winemaking, grapes have been grown for the production of raisins. The earliest act of cultivation appears to have been the favoring of hermaphroditic members of the Vitis vinifera species over the barren male vines and the female vines, which were dependent on a nearby male for pollination. With the ability to pollinate itself, over time the hermaphroditic vines were able to sire offspring that were consistently hermaphroditic. At the end of the 5th century BC, the Greek historian Thucydides wrote: The period that Thucydides was most likely referencing was the time between 3000 BC and 2000 BC, when viticulture emerged in force in Asia Minor, Greece, and the Cyclades Islands of the Aegean Sea. During this period, grape cultivation developed from an aspect of local consumption to an important component of international economies and trade. From 1200 BC to 900 BC, the Phoenicians developed viticulture practices that were later used in Carthage. Around 500 BC, the Carthaginian writer Mago recorded such practices in a two-volume work that was one of the few artifacts to survive the Roman destruction of Carthage during the Third Punic War. The Roman statesman Cato the Elder was influenced by these texts, and around 160 BC he wrote De Agricultura, which expounded on Roman viticulture and agriculture. Around 65 AD, the Roman writer Columella produced the most detailed work on Roman viticulture in his twelve-volume text De Re Rustica. Columella's work is one of the earliest to detail trellis systems for raising vines off the ground. Columella advocated the use of stakes versus the previously accepted practice of training vines to grow up along tree trunks. The benefits of using stakes over trees was largely to minimize the dangers associated with climbing trees, which was necessary to prune the dense foliage in order to give the vines sunlight, and later to harvest them. Roman expansion across Western Europe brought Roman viticulture to the areas that would become some of the world's best-known winegrowing regions: the Spanish Rioja, the German Mosel, and the French Bordeaux, Burgundy and Rhône. Roman viticulturists were among the first to identify steep hillsides as one of the better locations to plant vines, because cool air runs downhill and gathers at the bottom of valleys. While some cool air is beneficial, too much can rob the vine of the heat it needs for photosynthesis, and in winter it increases the risk of frost.
