Flavescence Dorée
Flavescence dorée (from French "Flavescence" : yellowing and "dorée" : golden) is one of the most important and damaging phytoplasma diseases of the vine with the potential to threaten vineyards. The bacterial agent has recently been named '' Candidatus Phytoplasma vitis'', and its vector is the leafhopper, '' Scaphoideus titanus''. Infection may kill young vines and greatly reduce the productivity of old vines. It is classified as a phytoplasma disease belonging to the group generically termed grapevine yellows.winepros.com.au. Occurrences are in sporadic epidemics, and varieties vary in their sensitivity to it. There is no cure at the moment and the way to manage its spread is by uprooting infected plants and by using selective insecticides in an area-wide pest management approach in order to reduce the hemipteran vectors. Symptoms The incubation period between infection and obvious symptoms is usually one year or more, depending on the response of the plant to both pathogen ...

Candidatus Phytoplasma Vitis
In prokaryote nomenclature, ''Candidatus'' (Latin for candidate of Roman office) is used to name prokaryotic phyla that are well characterized but yet-uncultured. Contemporary sequencing approaches, such as 16S sequencing or metagenomics, provide much information about the analyzed organisms and thus allow to identify and characterize individual species. However, the majority of prokaryotic species remain uncultivable and hence inaccessible for further characterization in ''in vitro'' study. The recent discoveries of a multitude of candidate taxa has led to candidate phyla radiation expanding the tree of life through the new insights in bacterial diversity. Nomenclature History The initial International Code of Nomenclature of Prokaryotes as well as early revisions did not account for the possibility of identifying prokaryotes which were not yet cultivable. Therefore, the term ''Candidatus'' was proposed in the context of a conference of the International Committee on Systemati ...

New York Wine
New York wine refers to wine made from grapes grown in the U.S. state of New York. New York ranks third in grape production by volume after California and Washington. 83% of New York's grape area is ''Vitis labrusca'' varieties (mostly Concord). The rest is split almost equally between ''Vitis vinifera'' and French hybrids. History The state of New York's wine production began in the 17th century with Dutch and Huguenot plantings in the Hudson Valley region. Commercial production did not begin until the 19th century. New York is home to the first bonded winery in the United States of America, Pleasant Valley Wine Company, located in Hammondsport. It is also home to America's oldest continuously operating winery, Brotherhood Winery in the Hudson Valley, which has been making wine for almost 175 years. In 1951 Konstantin Frank emigrated from Ukraine to New York, to work at Cornell University's Geneva Experiment Station. Frank went on to become one of the major architects of m ...

Italian Wine
Italian wine is produced in every region of Italy. Italy is the world's largest producer of wine, with an area of under vineyard cultivation, and contributing a 2013–2017 annual average of 48.3 million hl of wine. In 2018 Italy accounted for 19 per cent of global production, ahead of France (17 per cent) and Spain (15 per cent). Italian wine is both exported around the world and popular domestically among Italians, who consume an average of 42 litres per capita, ranking fifth in world wine consumption. The origins of vine-growing and winemaking in Italy has been illuminated by recent research, stretching back even before the Phoenician, Etruscans and Greek settlers, who produced wine in Italy before the Romans planted their own vineyards. The Romans greatly increased Italy's viticultural area using efficient viticultural and winemaking methods. History Vines have been cultivated from the wild ''Vitis vinifera'' grape for millennia in Italy. It was previously believed that ...

German Wine
German wine is primarily produced in the west of Germany, along the river Rhine and its tributaries, with the oldest plantations going back to the Ancient Rome, Roman era. Approximately 60 percent of German wine is produced in the state of Rhineland-Palatinate, where 6 of the 13 regions (''Anbaugebiete'') for quality wine are situated. Germany has about 103,000 hectares (252,000 acres or 1,030 square kilometers) of vineyard, which is around one tenth of the vineyard surface in Spain, France or Italy. The total wine production is usually around 10 million hectoliters annually, corresponding to 1.3 billion bottles, which places Germany as the eighth-largest wine-producing country in the world. White wine accounts for almost two thirds of the total production. As a wine country, Germany has a mixed reputation internationally, with some consumers on the export markets associating Germany with the world's most elegant and aromatically pure white wines while other see the country mainl ...

Bordeaux Wine
Bordeaux wine ( oc, vin de Bordèu, french: vin de Bordeaux) is produced in the Bordeaux region of southwest France, around the city of Bordeaux, on the Garonne River. To the north of the city the Dordogne River joins the Garonne forming the broad estuary called the Gironde; the Gironde department, with a total vineyard area of over 120,000 hectares, is the largest wine growing area in France. Average vintages produce over 700 million bottles of wine, ranging from large quantities of everyday table wine, to some of the most expensive and prestigious wines in the world. The vast majority of wine produced in Bordeaux is red (sometimes called "claret" in Britain), with sweet white wines (most notably Sauternes), dry whites, and (in much smaller quantities) rosé and sparkling wines (Crémant de Bordeaux) collectively making up the remainder. Bordeaux wine is made by more than 8,500 producers or ''châteaux''. There are 54 appellations of Bordeaux wine. History Viticulture ...

Rhône Wine
The Rhône wine region in Southern France is situated in the Rhône valley and produces numerous wines under various ''Appellation d'origine contrôlée'' (AOC) designations. The region's major appellation in production volume is Côtes du Rhône AOC. The Rhône is generally divided into two sub-regions with distinct vinicultural traditions, the Northern Rhône (referred to in French as ''Rhône septentrional'') and the Southern Rhône (in French ''Rhône méridional''). The northern sub-region produces red wines from the Syrah grape, sometimes blended with up to 20% of white wine grapes, and white wines from Marsanne, Roussanne and Viognier grapes. The southern sub-region produces an array of red, white and rosé wines, often blends of several grapes such as in Châteauneuf-du-Pape AOC, Châteauneuf-du-Pape. History The first cultivated vines in the region were probably planted around 600 BC. The origins of the two most important grape varieties in the northern Rhone (Syrah an ...

Cognac, France
Cognac (; Saintongese: ''Cougnat''; oc, Conhac ) is a commune in the Charente department, southwestern France. Administratively, the commune of Cognac is a subprefecture of the Charente department. Name The name is believed to be formed from individual masculine name -Connius, Gallic name, and the suffix -acum, which would correspond to the "domain of Connius". History The town of Cognac was unknown before the ninth century, when it was fortified. During the Hundred Years' War, the town continually changed sides, according to the tides of war. In 1526, it lent its name to the War of the League of Cognac, the military alliance established by King Francis I of France to fight against the House of Habsburg. As a benefit of the War League of Cognac, King Francis I granted to the town of Cognac the commercial right to participate in the salt trade conducted along the river, from which regional Cognac developed into a centre for the production of wine and brandy. In November 165 ...

Wine
Wine is an alcoholic drink typically made from fermented grapes. Yeast consumes the sugar in the grapes and converts it to ethanol and carbon dioxide, releasing heat in the process. Different varieties of grapes and strains of yeasts are major factors in different styles of wine. These differences result from the complex interactions between the biochemical development of the grape, the reactions involved in fermentation, the grape's growing environment (terroir), and the wine production process. Many countries enact legal appellations intended to define styles and qualities of wine. These typically restrict the geographical origin and permitted varieties of grapes, as well as other aspects of wine production. Wines not made from grapes involve fermentation of other crops including rice wine and other fruit wines such as plum, cherry, pomegranate, currant and elderberry. Wine has been produced for thousands of years. The earliest evidence of wine is from the Caucasus ...
