The grape of history is the Old World Vitis vinifera, the "wine-bearing Vitis," probably native to Asia. The paramount use of the grape always has been the production of wine. A secondary value is the production of raisins; and another is fruit for the dessert and for culinary uses. Great efforts were made to introduce the cultivation of the European grape into the American colonies, but they resulted in failure. It was not until the latter part of the last century that the chief causes of this failure became known: the depredations of the phylloxera and mildew,—and even then the causes were discovered largely because these American parasites had made incursions into the vineyards of Europe. In the meantime, one or two of the native species of Vitis had been ameliorated, and American viticulture had become established on a unique and indigenous basis, and the fruits are grown to eat rather than to drink. So fully did these early American ventures follow European customs that the grapes were usually planted on terraced slopes, as they are on the Rhine and about the continental lakes. Those early experiments finally failed because of the black-rot.

North America is richest in species of Vitis (see the article Vitis). These species range from ocean to ocean and from the British possessions to the tropics. The species that has been most improved is Vitis Labrusca of the Atlantic slope, although it seems to possess less native merit than some of the southwestern species types. Of this species are the Concord and Catawba types. To some extent it has been hybridized with Vitis vinifera (as in Agawam, Lindley, Barry, and others of E. S. Rogers' varieties), and with native species. Already a number of the popular varieties represent such wide departures that they cannot be referred positively to any species. Of these, Delaware and Isabella are examples. The second most important species, in point of amelioration, is Vitis aestivalis, from which several of the best wine grapes have sprung. The post-oak grape (Vitis lincecumii, or V. aestivalis Var. lincecumii) of the Southwest, is one of the most promising species, and already has given excellent results in hybridization. The Muscadine (V. rotundifolia) of the South has given the Scuppernong and a few less known forms. Beyond these species, there are none which has given varieties of great commercial importance, although considerable has been done in improving them. Some of the best of the wild species are practically untouched; there is only a comparatively small area of our great country which has yet developed large interests in grape-growing: the grape-types of a century hence, therefore, may be expected to be very unlike the present- day varieties. For an extended sketch of American grape history, see Bailey, "Evolution of Our Native Fruits" (1898). The American grape literature is voluminous. More than fifty authors have written on the subject. Yet there is very little of this writing which catches the actual spirit of American" grape- growing; this fact, together with the technicality and diversity of the subject itself, makes it seem wise to devote considerable space to the grape in this Cyclopedia.

While the native grape was being ameliorated in the East, the Old World Vitis vinifera was becoming established on the Pacific slope. In fact, Vitis vinifera has there run wild. The phylloxera and mildew are not native there, and the climate better suits the species. The Pacific coast viticulture, therefore, is of the Old World kind.

The current systems of pruning renew to a head—or to the main trunk—each year. The trunk is carried up to the desired height—to one of the wires of the trellis—and one or more canes are taken out from its top each year. The object is to keep the bearing wood near the main trunk and to obviate the use of spurs. This type of pruning is illustrated in Fig. 1716. This engraving shows the head of a vine seven years old, and on which two canes are allowed to remain after each annual pruning. The part extending from b to f and d is the base of the bearing cane of 1914. In the winter of 1914-15, this cane is cut off at d, and the new cane, e, is left to make the bearing wood of 1915. Another cane arose from /, but it was too weak to leave for fruiting. It was, therefore, cut away. The old stub, b, f, d, will be cut away a year hence, in the winter of 1915-16. In the mean- tune, a renewal cane will have grown from the stub c, which is left for that purpose, and the old cane, b d, will be cut off just beyond it, between c and /. In this way, the bearing wood is kept close to the head of the vine. The wound a shows where an old stub was cut away this winter, 1914-15, while b shows where one was cut off the previous winter. A scar on the back of the head, which does not show in the illustration, marks the spot where a stub was cut away two years ago, in the winter of 1912-13. This method of pruning can be kept up almost indefinitely, and if care is exercised in keeping the stubs short, the head will not enlarge out of proportion to the growth of the stock or trunk.

+
Two common styles of training are in use in the northern states, but each of them practises essentially the system of renewals described in the last paragraph. One stvlc of training carries the trunk only to the lowest wire of the trellis. The canes—usually two in number— are tied horizontally on the bottom wire, and the bearing shoots are tied, as they grow, to the two wires above (Fig. 1717). This is an upright system. The other style carries the trunk to the top wire. The canes are tied on the top wire, and the bearing shoots hang. This is the drooping or Kniffin system. If the shoots run out on the top wire by clinging to it by tendrils, they are torn loose, so that they will hang: this is a very necessary practice. There is controversy as to the comparative merits of these systems, which proves that each has merit. It is probable that the upright system is better for the slender or shorter varieties, as Delaware, and also for those whose shoots stand erect, as Catawba. The Kniffin has distinct merit for strong- growing varieties, as Concord; it is also cheaper, since it requires no summer tying. This system is well illustrated (as given by E. W. Williams in "Garden and Forest," I: 461) in Figs. 1718-1720.

One- or two-year-old vines are planted either in the fall or early spring. At planting, the vine is cut back to three or four buds, and the roots are shortened (Fig. 1724). If all buds start, the strongest one or two may be allowed to grow. The canes arising from this bud should be staked and allowed to grow through the season; or in large plantations the first-year canes may be allowed to lie on the ground. The second year this cane should be cut back to the same number of eyes as the first year. After growth begins in the second spring, one of the strongest shoots should be allowed to remain. This cane may be grown to a single stake through the second summer. At the end of the second year the cane may be cut back to the bottom wire of the trellis, if upright training is to be employed. The cane may be strong enough at this time to be made the permanent trunk of the Kniffin training, but in most cases the trunk is not carried to the top wire until the third year. The main pruning is performed when the vine is dormant. The ideal time is January and February in the North, although the work is often begun in November if the area is large. Pruning in spring causes the vine to bleed, but bleeding is not injurious. But late pruning interferes with tillage, and the buds are likely to be injured after they are swollen. Summer pruning is now practised only to the extent of pulling out suckers and weak shoots and even this is not always done. Heading-in the vine in summer is likely to start side growths, which are useless and troublesome.

The commercial propagation of grapes is accomplished by means of hardwood cuttings. These cuttings are taken in the winter from the trimmings of vineyards. In all ordinary cases they are made of two or three buds' length, preferably three (Fig. 1721). They are cut as soon as the canes are trimmed, tied in small bundles, and these bundles are then buried half their depth in damp sand in a cool cellar. By spring the cuttings will be more or less callused. The cuttings are planted in the open on the approach of warm weather. A loose loamy soil is chosen, and it is well and deeply prepared. The cuttings arc inserted until only the upper bud stands at the surface of the ground. These cuttings are placed 6 to 8 inches apart in rows, and the rows are far enough apart to allow of horse cultivation. These cuttings may give plants large enough for sale the following autumn; but it is usually preferred to let the plants grow two years before they are put upon the market. In such cases it is customary in many of the best nurseries, to transplant at the end of the first season. When wood is scarce, the canes are sometimes cut to single eyes. In this case about an inch of wood is left on either side of the bud. Single-eye cuttings are nearly always started under glass, preferably on the greenhouse bench. If they are started in February, they will be large enough for transplanting in a well-prepared seed-bed very early in the spring. Greenwood cuttings are sometimes used in the summer with new and rare varieties, but they are not in general favor. In California, rooted vines of one year are preferred; and in soil in which cuttings root readily, they are sometimes planted directly in the vineyard.

The grape is easily grafted. Because of the flexible nature of the vine, however, it is customary to make the graft below the surface of the ground. An ordinary cleft-graft is usually employed. The whole vine is cut off 4 or 5 inches below the surface, and the graft is inserted in the same fashion as in apple or pear trees. The surface may then be waxed or covered with clay or other material, to keep the water out of the cleft, although if the earth is firmly packed around the graft and no water stands, the union may be perfectly satisfactory without any cover. (Figs. 1722, 1723.) Vines of any age may be grafted. It is important that the cions be perfectly dormant. These cions are taken and stored in the same way as cuttings. The grafting should be done very early in the spring, before the sap starts. Grafting may also be performed late in the spring, after all danger of bleeding is over; but, in that case, it is more difficult to keep the cions dormant, and

Vineyards composed of unprofitable varieties may be changed to new varieties very readily by this means. Vinifera varieties can also be grafted on our common phylloxera-resistant stocks by the same method. Almost any method of grafting can be employed upon the grape-vine if the work is done beneath the surface.

Cultivation is thorough for best results. The vines are sometimes intercropped with cultivated crops the first year after plant- ^;^; ing, but later they require all the care. The vines are plowed up in the fall and disced and grape-hoed away the following spring. Cover- crops are sometimes used, but the practice is not an extensive one because of damp conditions for harvesting in the fall. Cover- crops are sometimes not plowed under till the following spring. The tying is done by women and girls in early spring before the buds are so swollen that they are easily damaged. Many materials are used, but the most common are wire and a soft wool twine made for the purpose. The twine is most used, although the wire is very handy. The canes are spaced when tying, and thus held in place until the tendrils of the new shoots secure them to the wire.

Fertilizing is still done in a haphazard way. Some of the best men make a regular practice of mulching the roots with farmyard manure in the fall. Some apply no farmyard manure at all. The use of commercial fertilizer is still in the experimental stage. Its value is admitted but its use is not fully understood. On light and gravel soils some potash compounds are being used. On the deep alluvial soils some growers are using it in the form of wood-ashes rather than the prepared commercial product. Some bone-meal, at the rate of 300 to 600 pounds to the acre, is being used also. Some state profitable results from their methods; others think that with light applications of farmyard manure and thorough cultivation the commercial fertilizers are not required.

A '''grape''' is the [[fruit]] that grows on the woody [[vine]]s of the [[family (biology)|family]] [[Vitaceae]]. Grapes grow in clusters of 6 to 300, and can be black, blue, golden, green, purple, red, pink, brown, peach or white. They can be eaten raw or used for making [[jam]], [[grape juice]], [[jelly]], [[wine]] and [[grape seed oil]]. Cultivation of grapevines occurs in [[vineyard]]s, and is called [[viticulture]]. One who studies and practices growing grapes for wine is called a viticulturist.

According to the "Food and Agriculture Organization" (FAO), 75,866 square kilometres of the world is dedicated to grapes. Approximately 71% of world grape production is used for wine, 27% as fresh fruit, and 2% as dried fruit. A portion of grape production goes to producing grape juice to be used as a sweetener for fruits canned "with no added sugar" and "100% natural". The area dedicated to vineyards is increasing by about 2% per year. <!-- references needed: Popularity for the purple grape has increased tremendously over the past decade. In March 2006, the purple grape reached its peak in popularity by being preferred 83% of the time over green grapes in a University of Michigan poll. -->

Comparing diets among western countries, researchers have discovered that although the French tend to eat higher levels of animal fat, surprisingly the incidence of [[heart disease]] remains low in France.[http://www.virginia.edu/bmg/faculty/mayo/mayo.html] This phenomenon has been named the [[French Paradox]]. Many scientists now believe the reason is the greater consumption of red wine in France. Something in the grape helps to lower cholesterol levels in the body and thus slows the build up of deposits in the arteries. Compounds such as [[resveratrol]] (a [[polyphenol antioxidant]]) have been discovered in grapes and these have been positively linked to fighting cancer, [[heart disease]], degenerative [[nerve]] disease and other ailments. Doctors do not recommend excessive consumption of red wine, but three or four glasses a week is beneficial and encouraged.
  −
 
  −
Red or not, grapes of all colors offer comparable benefits. Red [[wine]] offers health benefits not found in white wine, because many of the beneficial compounds are found in the skins of the grapes, and only red wine is fermented with the skins.

== Raisins, currants, and sultanas ==
  −
A ''[[raisin]]'' is any dried grape. A ''[[Zante currant|currant]]'' is a dried [[Zakynthos|Zante]] grape, the name being a corruption of the [[French language|French]] ''raisin de Corinthe'' ([[Corinth]] grape). A ''[[sultana (grape)|sultana]]'' was originally a raisin made from a specific type of grape of Turkish origin, but the word is now applied to raisins made from common North American grapes and chemically treated to resemble the traditional sultana.
  −
 
  −
Note that, while ''raisin'' is a French [[loanword]], the word in French refers to the fresh fruit; ''grappe'' (from whence the English ''grape'') refers to the bunch (as in ''une grappe de raisin'').  As ''raisin'' is uncountable in French, a single grape is a ''grain de raisin.''
  −
 
  −
Note also that ''currant'' has come to refer also to the [[blackcurrant]] and [[redcurrant]], two berries completely unrelated to grapes.
  −
 
  −
== Seedlessness ==
  −
Seedlessness is a highly desirable trait in table grape selection, and seedless cultivars now make up the overwhelming majority of table grape plantings. Because grapevines are [[Vegetative reproduction|vegetatively propagated]] by cuttings, the lack of seeds does not present a problem for reproduction. It is, however, an issue for breeders, who must either use a seeded variety as the female parent or resc
  −
ue embryos early in development using [[Plant tissue culture|tissue culture]] techniques. There are several sources of the seedlessness trait, and essentially all commercial cultivars get it from one of three sources: Thompson Seedless, Russian Seedless, and Black Monukka. All are members of ''[[Vitis vinifera]]''.

==Resveratrol==
  −
{{main|Resveratrol}}
  −
[[Resveratrol]] is produced by several plants, apparently for its [[antifungal drug|antifungal]] properties. It is found in widely varying amounts in grapes, primarily the skins and seeds.  This is particularly true for muscadine grapes, whose skin and seeds have about one hundred times the concentration as the pulp.[http://etd.lsu.edu/docs/available/etd-01202006-082858/] The amount found in grape skins also varies with the grape cultivar, its geographic origin, and exposure to fungal infection. The amount of fermentation time a wine spends in contact with grape skins is an important determinant of its resveratrol content.[http://www.pbrc.edu/Division_of_Education/pdf/PNS_resveratrol.pdf]
  −
 
  −
Fresh grape skin contains about 50 to 100 micrograms of resveratrol per gram.[http://www.mercola.com/2004/jun/9/grape_skin.htm] Ordinary non-[[muscadine]] [[red wine]] contains between 0.2 and 5.8 mg/L <ref> Gu X, Creasy L, Kester A, et al., Capillary electrophoretic determination of resveratrol in wines.  J Agric Food Chem 47:3323-3277, 1999</ref>, depending on the grape variety, while white wine has much less - the reason being that red wine is [[fermentation (food)|fermented]] with the skins, allowing the wine to absorb the resveratrol, whereas [[white wine]] is fermented after the skin has been removed. Wines produced from [[muscadine]] grapes, however, both red and white, may contain more than 40 mg/L.<ref> Ector BJ, Magee JB, Hegwood CP, Coign MJ.  Resveratrol Concentration in Muscadine Berries, Juice, Pomace, Purees, Seeds, and Wines.  http://www.ajevonline.org/cgi/content/abstract/47/1/57</ref>.
