Grobe
Gouais blanc () or Weißer Heunisch () is a white grape variety that is seldom grown today but is important as the ancestor of many traditional French and German grape varieties. The name ''Gouais'' derives from the old French adjective ‘gou’, a term of derision befitting its traditional status as the grape of the peasants. Likewise, the German name Weißer Heunisch labels it as one of the lesser " Hunnic" grapes. History Gouais is known to have been widely planted in central and northeastern France in Medieval times. At that time, it was used to produce simple, acidic, white wines, and was primarily grown in unfavourable plots less well-suited for the more highly regarded Pinot noir or Pinot gris. Gouais Blanc was thus the grape of the peasantry rather than of the nobility. Its history before Medieval times is not known with any certainty, but is the subject of much conjecture, similar to many other grape varieties with a long history. Gouais blanc has been proposed a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grape Variety
This list of grape varieties includes cultivated grapes, whether used for wine, or eating as a table grape, fresh or dried (raisin, currant, sultana). For a complete list of all grape species including those unimportant to agriculture, see Vitis. The term ''grape variety'' refers to cultivars rather than actual 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 using the term ''cultivar'' instead is unlikely. Single species grapes While some of the grapes in this list are hybrids, they are hybridized within a single species. For those grapes hybridized across species, known as interspecific hybrids, see the section on multispecies hybrid grapes below.

Gouache
Gouache (; ), body color, or opaque watercolor is a water-medium paint consisting of natural pigment, water, a binding agent (usually gum arabic or dextrin), and sometimes additional inert material. Gouache is designed to be opaque. Gouache has a considerable history, having been used for at least twelve centuries. It is used most consistently by commercial artists for posters, illustrations, comics, and other design work. Gouache is similar to watercolor in that it can be re-wetted and dried to a matte finish, and the paint can become infused into its paper support. It is similar to acrylic or oil paints in that it is normally used in an opaque painting style and it can form a superficial layer. Many manufacturers of watercolor paints also produce gouache, and the two can easily be used together. Description Gouache paint is similar to watercolor, but is modified to make it opaque. Just as in watercolor, the binding agent has traditionally been gum arabic but since t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Austria
Austria, , bar, Östareich officially the Republic of Austria, is a country in the southern part of Central Europe, lying in the Eastern Alps. It is a federation of nine states, one of which is the capital, Vienna, the most populous city and state. A landlocked country, Austria is bordered by Germany to the northwest, the Czech Republic to the north, Slovakia to the northeast, Hungary to the east, Slovenia and Italy to the south, and Switzerland and Liechtenstein to the west. The country occupies an area of and has a population of 9 million. Austria emerged from the remnants of the Eastern and Hungarian March at the end of the first millennium. Originally a margraviate of Bavaria, it developed into a duchy of the Holy Roman Empire in 1156 and was later made an archduchy in 1453. In the 16th century, Vienna began serving as the empire's administrative capital and Austria thus became the heartland of the Habsburg monarchy. After the dissolution of the H ...

Beaunoir
Beaunoir is a traditional French variety of red wine grape that is a sibling of Chardonnay. The 'beautiful black' grape produces a thin wine and not much is grown these days. History DNA fingerprinting has shown that it is one of many grapes to be the result of a cross between Gouais blanc (Heunisch) and Pinot, making it a full sibling of famous varieties such as Chardonnay and Aligoté. Gouais blanc was widely grown by the French peasantry in the Medieval ages. This offered many opportunities for hybridisation, and the offspring benefited from hybrid vigour as the parents were genetically quite different. Other Gouais blanc/Pinot crosses include Aubin vert, Auxerrois, Bachet noir, Franc Noir de la-Haute-Saône, Gamay Blanc Gloriod, Gamay noir, Melon, Knipperlé, Peurion, Romorantin, Roublot, and Sacy Viticulture Beaunoir is quite vigorous, producing small compact bunches of small grapes. Wine regions Like Bachet noir, Beaunoir has almost disappeared from its home in Châ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bachet Noir
Bachet noir is a traditional French variety of red wine grape that is a sibling of Chardonnay. A little is still grown in the Aube, where it is used to add colour and body to Gamay wines. History DNA fingerprinting has shown that it is one of many grapes to be the result of a cross between Gouais blanc (Heunisch) and Pinot noir, making it a sibling of famous varieties such as Chardonnay and Aligoté. Gouais blanc was widely grown by the French peasantry in the Medieval ages. This offered many opportunities for hybridization, and the offspring benefited from hybrid vigour as the parents were genetically quite different. The fact that it is now only found in the Aube, and is descended from grapes that have been grown locally for hundreds of years, suggests that it originated to the north of Burgundy. Other Gouais blanc/Pinot crosses include Aubin vert, Auxerrois, Beaunoir, Franc Noir de la-Haute-Saône, Gamay Blanc Gloriod, Gamay noir, Melon, Knipperlé, Peurion, Romorantin, ...

Aubin Vert
Aubin vert is a white French wine grape variety that is grown in the Lorraine region where it is an authorized variety for the ''Appellation d'Origine Contrôlée'' (AOC) wines of the Moselle. While often confused for the Côtes de Toul grape Aubin blanc, DNA analysis in 1999 showed that Aubin vert was the result of a crossing of Gouais blanc with Pinot (an ancestor vine to Pinot noir). This makes the grape a half-sibling to Aubin blanc (a cross of Gouais blanc and the Jura wine grape Savagnin) but full sibling to Chardonnay, Aligoté, Gamay and Melon de Bourgogne.J. Robinson, J. Harding and J. Vouillamoz ''Wine Grapes – A complete guide to 1,368 vine varieties, including their origins and flavours'' pgs 64–65, Allen Lane 2012 History Ampelographers believe that first recorded mention of Aubin vert was in 1722 when a variety known as ''Aubins'' was recorded growing in the Moselle region by a document from the parliament of Metz. The plural usage of Aubins suggest that A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aligoté
Aligoté is a white grape used to make dry white wines, especially in the Burgundy region of France where it was first recorded in the 18th century.winepros.com.au. Since it is tolerant to cold, this variety is also cultivated in Eastern European countries. In 2004, it was the 22nd most planted vine variety in the world at 45,000 hectares (110,000 acres). Description Aligoté is used to produce a varietal white wine, and is sometimes included in the blend of Burgundian sparkling wine known as Crémant de Bourgogne. In the varietal appellation Bourgogne Aligoté AOC, up to 15% Chardonnay grapes may be blended in. Traditionally, the cocktail '' kir'' (also known as ''vin blanc cassis'' in French) is made by adding cassis to an Aligoté wine. In blends, Aligoté adds acidity and structure to other varieties. It is often blended with Sacy for this purpose.J. Robinson ''Vines, Grapes & Wines'' pg 232 Mitchell Beazley 1986 The grape ripens early with moderate yields and produ ...

Chardonnay
Chardonnay (, , ) is a green-skinned grape variety used in the production of white wine. The variety originated in the Burgundy wine region of eastern France, but is now grown wherever wine is produced, from England to New Zealand. For new and developing wine regions, growing Chardonnay is seen as a 'rite of passage' and an easy entry into the international wine market. The Chardonnay grape itself is neutral, with many of the flavors commonly associated with the wine being derived from such influences as '' terroir'' and oak.Robinson, 2006, pp. 154–56. It is vinified in many different styles, from the lean, crisply mineral wines of Chablis, France, to New World wines with oak and tropical fruit flavors. In cool climates (such as Chablis and the Carneros AVA of California), Chardonnay wine tends to be medium to light body with noticeable acidity and flavors of green plum, apple, and pear. In warmer locations (such as the Adelaide Hills and Mornington Peninsula in Aus ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Heterosis
Heterosis, hybrid vigor, or outbreeding enhancement is the improved or increased function of any biological quality in a hybrid offspring. An offspring is heterotic if its traits are enhanced as a result of mixing the genetic contributions of its parents. These effects can be due to Mendelian or non-Mendelian inheritance. Definitions In proposing the term heterosis to replace the older term heterozygosis, G.H. Shull aimed to avoid limiting the term to the effects that can be explained by heterozygosity in Mendelian inheritance. Heterosis is often discussed as the opposite of inbreeding depression, although differences in these two concepts can be seen in evolutionary considerations such as the role of genetic variation or the effects of genetic drift in small populations on these concepts. Inbreeding depression occurs when related parents have children with traits that negatively influence their fitness largely due to homozygosity. In such instances, outcrossing sh ...

DNA Fingerprinting
DNA profiling (also called DNA fingerprinting) is the process of determining an individual's DNA characteristics. DNA analysis intended to identify a species, rather than an individual, is called DNA barcoding. DNA profiling is a forensic technique in criminal investigations, comparing criminal suspects' profiles to DNA evidence so as to assess the likelihood of their involvement in the crime. It is also used in paternity testing, to establish immigration eligibility, and in genealogical and medical research. DNA profiling has also been used in the study of animal and plant populations in the fields of zoology, botany, and agriculture. Background Starting in the 1980s, scientific advances allowed the use of DNA as a material for the identification of an individual. The first patent covering the direct use of DNA variation for forensicsUS5593832A was filed by Jeffrey Glassberg in 1983, based upon work he had done while at Rockefeller University in the United States in 1981. ...
