Grape

A grape is a fruiting berry of the deciduous woody vines of the botanical genus Vitis.

Grapes can be eaten raw or they can be used for making wine, jam, juice, jelly, grape seed extract, raisins, vinegar, and grape seed oil. Grapes are a non-climacteric type of fruit, generally occurring in clusters.

History

The cultivation of the domesticated grape began 6,000–8,000 years ago in the Near East.Yeast, one of the earliest domesticated microorganisms, occurs naturally on the skins of grapes, leading to the innovation of alcoholic drinks such as wine. The earliest archeological evidence for a dominant position of wine-making in human culture dates from 8,000 years ago in Georgia. The oldest winery was found in Armenia, dating to around 4000 BC. By the 9th century AD the city of Shiraz was known to produce some of the finest wines in the Middle East. Thus it has been proposed that Syrah red wine is named after Shiraz, a city in Persia where the grape was used to make Shirazi wine. Ancient Egyptian hieroglyphics record the cultivation of purple grapes, and history attests to the ancient Greeks, Phoenicians, and Romans growing purple grapes for both eating and wine production. The growing of grapes would later spread to other regions in Europe, as well as North Africa, and eventually in North America.

Shades of violet

There are numerous variations of the color violet, a sampling of which are shown below.

Variations of the color violet

Variations of spectral violet

Although pure spectrum violet is outside the color gamut of the RGB color space, the three colors displayed below are rough approximations of the range of colors of actual spectral violet, although the accuracy of the approximation can vary depending on the individual's color vision, and on the color rendition of one's computer monitor.

Color wheel violet

The tertiary color on the HSV color wheel (also known as the RGB color wheel) precisely halfway between blue and magenta is called color wheel violet. This tone of violet—an approximation of the color violet at about 417 nanometers as plotted on the CIE chromaticity diagram—is shown at right. This tone of violet is actually somewhat toward indigo assuming indigo is accepted as a separate spectrum color, usually quoted as having a range of from about 420 to 450 nanometers. Another name for this color is near violet.

List of grape varieties

This list of grape varieties includes cultivated grapes, whether used for wine, or eating as a table grape, fresh or dried (raisin, currant, sultana).

The term grape variety actually refers to cultivars rather than botanical varieties according to the International Code of Nomenclature for Cultivated Plants, because they are propagated by cuttings and may have unstable reproductive properties. However, the term variety has become so entrenched in viticulture that any change to usage of the term cultivar is unlikely.

Single species grapes

While some of the grapes in this list are hybrids, they are hybridized within between different species within the same genus also known as interspecific hybrids. For those grapes hybridized across species, see the section on multispecies hybrid grapes below.

GRAPE

GRAPE (Computers), or GRAphics Programming Environment is a software development environment for mathematical visualization, especially differential geometry and continuum mechanics. In 1994, it won the European Academic Software Award.

The term graphical refers to the applications; the programming itself is mostly based on C. GRAPE was developed by the University of Bonn in Germany and is available for free for non-commercial purposes. It has not been developed actively since 1998.

qfix Grape

Another graphical programming environment called GRAPE is developed by qfix and the University of Ulm. Here, it is used as a graphical tool for developing object oriented programs for controlling autonomous mobile robots. After arranging graphical program entities to receive the desired flow chart, the graphical program can be translated to source code (e.g. C++). A modular interface makes the environment easy to extend, so additional classes can be integrated or different flowchart-to-code translator or compilers can be used.
