Duras (grape)
Duras is a traditional French variety of red wine grape that is mostly grown around the river Tarn, northeast of Toulouse. It is usually blended with other traditional varieties, but production has been declining in recent years. Despite the name the grape appears to have no connection with the Côtes de Duras east of Bordeaux, and is not grown there today.J. Robinson ''Vines, Grapes & Wines'' pg 205 Mitchell Beazley 1986 Nor is there any known link with the Durasa of Piedmont. History Viticulture came to the Tarn with the Romans, but little is known of the history of Duras. DNA fingerprinting has recently suggested that with Petit Verdot from Bordeaux, it is a parent of the Tressot variety. , accessed on December 15, 2009 Distribution ...

Vitis Vinifera
''Vitis vinifera'', the common grape vine, is a species of flowering plant, native to the Mediterranean region, Central Europe, and southwestern Asia, from Morocco and Portugal north to southern Germany and east to northern Iran. There are currently between 5,000 and 10,000 varieties of ''Vitis vinifera'' grapes though only a few are of commercial significance for wine and table grape production. The wild grape is often classified as ''Vitis vinifera'' ''sylvestris'' (in some classifications considered ''Vitis sylvestris''), with ''Vitis vinifera'' ''vinifera'' restricted to cultivated forms. Domesticated vines have hermaphrodite flowers, but ''sylvestris'' is dioecious (male and female flowers on separate plants) and pollination is required for fruit to develop. Grapes can be eaten fresh or dried to produce raisins, sultanas, and currants. Grape leaves are used in the cuisine of many cultures. The fresh grapes can also be processed into juice that is fermented to make wine ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Petit Verdot
Petit Verdot is a variety of red wine grape, principally used in classic Bordeaux blends. It ripens much later than the other varieties in Bordeaux, often too late, so it fell out of favour in its home region. When it does ripen it adds tannin, colour and flavour, in small amounts, to the blend. Petit verdot has attracted attention among winemakers in the New World, where it ripens more reliably and has been made into single varietal wine. It is also useful in 'stiffening' the mid palate of Cabernet Sauvignon blends. When young its aromas have been likened to banana and pencil shavings. Strong tones of violet and leather develop as it matures. History Petit Verdot probably predates Cabernet Sauvignon in Bordeaux, but its origins are unclear. There are records of it in the eighteenth century, but its characteristics suggest an origin in much hotter climes than the Gironde. It is one parent of Tressot, the other parent being Duras, a grape from the upper Tarn valley near Toulo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tannat
Tannat is a red wine grape, historically grown in South West France in the Madiran AOC, and is now one of the most prominent grapes in Uruguay, where it is considered the "national grape". Tannat is also grown in Argentina, Australia, Brazil, Bolivia, Peru, South Africa, and in the Italian region of Apulia, where it is used as a blending grape. In the US states of Maryland and Virginia, there are small experimental plantings of the vine, and plantings in California have increased dramatically in the first years of the 21st century. It has also been increasingly planted in Arizona, Oregon and Texas. Tannat wines produced in Uruguay are usually quite different in character from Madiran wines, being lighter in body and lower in tannins. It is also used to make full bodied rosé. In France, efforts to solve the harsh tannic nature of the grape led to the development of the winemaking technique known as micro-oxygenation. France Tannat is mainly found near the French Pyréné ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Black Rot
Black rot is a name used for various diseases of cultivated plants caused by fungi or bacteria, producing dark brown discoloration and decay in the leaves of fruit and vegetables: * A disease of the apple, pear and quince caused by a fungus (''Botryosphaeria obtusa'' or ''Physalospora cydoniae'') * A disease of grape vines caused by a fungus (''Guignardia bidwellii''), affecting the aboveground part of the vine, and favored by warm, humid weather; also called grape rot * A disease of cabbage and related plants caused by a bacterium (''Xanthomonas campestris pv. campestris''). Occurring around the world, it affects primarily the aboveground parts of plants. Vegetables in the crucifer family are susceptible, including broccoli, Brussels sprouts, cabbage, cauliflower, Chinese cabbage, kale, mustard, radish, rutabaga, and turnip. Many weeds may host this pathogen including Shepherd's Purse, wild mustard, and yellow rocket. * A disease of the potato caused by a bacterium (''Erwinia atrose ...

Uncinula Necator
''Uncinula necator'' (syn. ''Erysiphe necator'') is a fungus that causes powdery mildew of grape. It is a common pathogen of Vitis species, including the wine grape, ''Vitis vinifera''. The fungus is believed to have originated in North America. European varieties of ''Vitis vinifera'' are more or less susceptible to this fungus. ''Uncinula necator'' infects all green tissue on the grapevine, including leaves and young berries. It can cause crop loss and poor wine quality if untreated. The sexual stage of this pathogen requires free moisture to release ascospores from its cleistothecia in the spring. However, free moisture is not needed for secondary spread via conidia; high atmospheric humidity is sufficient. Its anamorph is called ''Oidium tuckeri''. It produces common odors such as 1-octen-3-one and (Z)- 1,5-octadien-3-one. This mildew can be treated with sulfur or fungicides; however resistance to several chemical classes such as Benomyl, the DMIs, and Strobilurins has ...

Négrette
Négrette is a dark red wine grape grown primarily in South West France (wine region), South West France in the region between Albi and Toulouse. Wine regions The principal appellation using this variety, Côtes du Frontonnais (red and rosé), requires that 50% to 70% of the blend be the Négrette grape. The other 50% to 30% must be some combination of Cabernet Franc and Cabernet Sauvignon (maximum 25% together), Côt (maximum 25%), Fer (maximum 25%), Syrah (maximum 25%), Cinsaut, Gamay, Mauzac (grape), Mauzac (a white grape), Merille (maximum 15% together). At least three grape varieties must be used. Wines Wine made from this grape tends to show versatility in being able to age moderately well and also be drunk young. In California the vine was known as ''Pinot St-George'' until 1997, when the BATF ruled that it may no longer be called that. In the Fiefs Vendeens of the Loire Valley, Négrette may be called 'Ragoutant'. The vine has declined in planting in the last century du ...

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.
