058 Vitis vinifera L.
Nome comune: Vite comune
Vitis vinifera (Common Grape Vine) is a species of Vitis, native to the Mediterranean region, central Europe, and southwestern Asia, from Morocco and Spain north to southern Germany and east to northern Iran.
It is a liana growing to 35 m tall, with flaky bark. The leaves are alternate, palmately lobed, 5–20 cm long and broad. The fruit is a berry, known as a grape; in the wild species it is 6 mm diameter and ripens dark purple to blackish with a pale wax bloom; in cultivated plants it is usually much larger, up to 3 cm long, and can be green, red, or purple. The species typically occurs in humid forests and streamsides.
The wild grape is often classified as V. vinifera subsp. sylvestris (in some classifications considered Vitis sylvestris), with V. vinifera subsp. vinifera restricted to cultivated forms. Domesticated vines have hermaphrodite flowers, but subsp. sylvestris is dioecious (male and female flowers on separate plants) and pollination is required for fruit to develop.
It is cultivated on every continent on Earth except for Antarctica. In Europe, in the central and southern regions; in Asia, in the western regions (Anatolia, Caucasus, Middle east) and in China; in Africa, along the northern Mediterranean coast and in South Africa; in North America, in California, Mexico and also other areas like New Mexico, New York, British Columbia, Ontario and Québec; in South America in Chile, Argentina, Uruguay and Brazil; in Oceania in Australia and New Zealand.
The appearance of Vitis vinifera has been dated to between 130 to 200 million years ago with the human relationship to the plant dating from the Neolithic period.
Wild grapes were harvested by foragers and early farmers. For thousands of years, the fruit has been harvested for both medicinal and nutritional value; its history is intimately entwined with the history of wine.
Changes in pip shape (narrower in domesticated forms) and distribution point to domestication occurring about 3500-3000 BCE, in southwest Asia, South Caucasus (Armenia and Georgia), or the Western Black Sea shore region (Bulgaria). Cultivation of the domesticated grape spread to other parts of the Old World in pre-historic or early historic times.
The first written accounts of grapes and wine can be found in the Epic of Gilgamesh and ancient Sumerian text from the third millennium BCE. There are also numerous hieroglyphic references from ancient Egypt, according to which wine was reserved exclusively for priests, state functionaries and the pharaoh.
Grape harvest on Etruscan terracotta from the 6th century AC.The ancient Greeks introduced grape growing and wine making to Europe in the Minoan age. Hesiod in his Works and Days gives detailed descriptions of grape harvests and wine making techniques, and there are also many references in Homer. Greek colonists then introduced these practices in their colonies, especial in southern Italy (Magna Grecia), which was even known as “Enotria” due to its propitious climate.
The Etruscans improved wine making techniques and developed an export trade even beyond the Mediterranean basin.
The ancient Romans further developed the techniques learnt from the Etruscans, as shown by numerous works of literature containing information that is still valid today: De Agri Cultura by Cato the Elder, De re rustica by Marcus Terentius Varro, the Georgics by Virgil and De re rustica by Columella.
During the 3rd and 4th centuries AD, the long crisis of the Roman Empire generated instability in the countryside which led to a reduction of viticulture in general, which was mainly sustained only close to towns and cities and along coastlines.
Between the 5th and 10th centuries, viticulture was sustained almost exclusively by the different religious orders in monasteries. The Benedictines and others extended the grape growing limit northwards and also planted new vineyards at higher altitudes than was customary before. Apart from ‘ecclesiastical’ viticulture, there also developed, especially in France, a ‘noble’ viticulture, practiced by the aristocracy as a symbol of prestige.
Vineyard (Burgundy)Grape growing was a significant economic activity in the Middle east up to the 7th century, when the expansion of Islam caused it to decline.
Between the Low Middle Ages and the Renaissance, viticulture began to flourish again. Demographic pressure, population concentration in towns and cities, and the increased spending power of artisans and merchants gave rise to increased investment in viticulture, which became economically feasible once more.
Much was written during the Renaissance on grape growing and wine production, favouring a more scientific approach. This literature can be considered the origin of modern ampelography.
Grapes followed European colonies around the world, coming to North America around the 17th century, and to Africa, South America and Australia. In North America it formed hybrids with native species from the Vitis genus; some of these were intentional hybrids created to combat phylloxera, an insect pest which affected the European grapevine to a much greater extent than North American ones and in fact managed to devastate European wine production in a matter of years. Later, North American rootstocks became widely used to graft V. vinifera cultivars so as to withstand the presence of phylloxera.
In the second half of the 20th century there was a shift in attitude in viticulture from traditional techniques to the scientific method based on fields such as microbiology, chemistry and ampelography. This change came about also due to changes in economic and cultural aspects and in the way of life and in the consumption habits of wide sectors of the population starting to demand quality products.
Nature magazine has published the genome sequence of V. vinifera. This work was the result of collaboration between Italian researchers (Consorzio Interuniversitario Nazionale per la Biologia Molecolare delle Piante, Istituto di Genomica Applicata) and French researchers (Genoscope e Institut National de la Recherche Agronomique). Vitis venifera is the fourth angiosperm species whose genome has been completely sequenced. The results of this analysis contribute significantly to understanding the evolution of plants over time and of the genes involved in the aromatic characteristics of wine.
In March 2007, scientists from Australia's CSIRO working in the Cooperative Research Centre for Viticulture reported that they found that "extremely rare and independent mutations in two genes [VvMYBA1 and VvMYBA2] [of red grapes] produced a single white grapevine that was the parent of almost all of the world's white grape varieties. If only one gene had been mutated, most grapes would still be red and we would not have the more than 3000 white grape cultivars available today."
Use of grapes is known to date back to Neolithic times, following the discovery in 1996 of 7,000 year-old wine storage jars in present-day northern Iran. Further evidence shows the Mesopotamians and Ancient Egyptians had vine plantations and winemaking skills. Greek philosophers praised the healing powers of grapes both whole and in the form of wine. Vitis vinifera cultivation and winemaking in China began during the Han Dynasty in the 2nd century with the importation of the species from Ta-Yuan. However, wild vine "mountain grapes" like Vitis thunbergii were being used for wine making before that time.
Using the sap of grapevines, European folk healers sought to cure skin and eye diseases. Other historical uses include the leaves being used to stop bleeding, pain and inflammation of hemorrhoids. Unripe grapes were used for treating sore throats, and raisins were given as treatments for consumption (tuberculosis), constipation and thirst. Ripe grapes were used for the treatment of cancer, cholera, smallpox, nausea, skin and eye infections as well as kidney and liver diseases.
Seedless grape varieties were developed to appeal to consumers, but researchers are now discovering that many of the healthful properties of grapes may actually come from the seeds themselves, thanks to their enriched phytochemical content.
Grapevine leaves are filled with minced meat (such as lamb or beef), rice and onions in the making of Balkan traditional dolma.
A grapevine is depicted on the reverse of the Croatian 2 lipa coin, minted since 1993.
