Regent (grape)
Regent is a dark-skinned inter-specific hybrid grapes, hybrid grape variety, used for making wine. It has both European (''Vitis vinifera'') and American vine species in its Plant breeding, pedigree and a broad resistance against the most significant fungal diseases which affect grapes, such as downy mildew. History Regent was created in 1967 by Professor Gerhardt Alleweldt at the Geilweilerhof Institute for Grape Breeding in Germany by crossing Diana, a Silvaner x Müller-Thurgau cross and thus a ''Vitis vinifera'' variety, with the interspecific hybrid Chambourcin.Vitis International Variety Catalogue: Regent

Silvaner
Silvaner or Sylvaner () is a variety of white wine grape grown primarily in Alsace wine, Alsace and German wine, Germany, where its official name is Grüner Silvaner. While the Alsatian versions have primarily been considered simpler wines, it was included among the varieties that can be used to produce Alsace Grand Cru AOC, Alsace Grand Cru wine in 2006, together with the four 'noble grapes' of Alsace, although only in one vineyard, Zotzenberg. This dichotomy is explained by the vigour of the Sylvaner vine and the grape's neutral flavour, which can lead to blandness unless yields are controlled. On the other hand, it gives a blank canvas for the expression of terroir, and on good sites with skilled winemaking, Sylvaner can produce elegant wines. It has high acidity but naturally reaches high must weights, so is often blended with other varieties such as Riesling or Elbling, and is sometimes made into a dessert wine. History Sylvaner is an ancient variety that has long been gr ...

Barrique
Oak is used in winemaking to vary the color, flavor, tannin profile and texture of wine. It can be introduced in the form of a barrel during the fermentation or aging periods, or as free-floating chips or staves added to wine fermented in a vessel like stainless steel. Oak barrels can impart other qualities to wine through evaporation and low level exposure to oxygen.J. Robinson ''Jancis Robinson's Wine Course'' Third Edition pg 91-93 Abbeville Press 2003 History In early wine history, the amphora was the vessel of choice for the storage and transportation of wine. Due to the perishable nature of wood material it is difficult to trace the usage of barrels in history. The Greek historian Herodotus noted that ancient Mesopotamians used barrels made of palm wood to transport wine along the Euphrates. Palm is a difficult material to bend and fashion into barrels, however, and wine merchants in different regions experimented with different wood styles to find a better wood source. ...

Must Weight
Must weight is a measure of the amount of sugar in grape juice (must) and, hence, indicates the amount of alcohol that could be produced if it is all fermented to alcohol, rather than left as residual sugar.Deutsches Weininstitut: Must weights
, accessed on March 26, 2009


Measurement is in degrees

In France and many other countries, the grape must density is often recalculated to show potential alcohol, the percent alcohol content that would be the result if the must were fermented to a completely dry wine.

Grape Tannins
Procyanidins are members of the proanthocyanidin (or condensed tannins) class of flavonoids. They are oligomeric compounds, formed from catechin and epicatechin molecules. They yield cyanidin when depolymerized under oxidative conditions. See the box below entitled "Types of procyanidins" for links to articles on the various types. Distribution in plants Procyanidins, including the lesser bioactive / bioavailable polymers (4 or more catechines), represent a group of condensed flavan-3-ols that can be found in many plants, most notably apples, maritime pine bark, cinnamon, aronia fruit, cocoa beans, grape seed, grape skin, and red wines of ''Vitis vinifera'' (the common grape). However, bilberry, cranberry, black currant, green tea, black tea, and other plants also contain these flavonoids.USDA, August 2004USDA Database for the Proanthocyanidin Content of Selected Foods PDF summary accessed from main USDA pag Page accessed July 31, 2015 Procyanidins can also be isolated fr ...

Appellation D'origine Contrôlée
In France, the ''appellation d'origine contrôlée'' (, ; abbr. AOC ) is a label that identifies an agricultural product whose stages of production and processing are carried out in a defined geographical area – the ''terroir'' – and using recognized and traditional know-how. The specificity of an AOC product is determined by the combination of a physical and biological environment with established production techniques transmitted within a human community. Together, these give the product its distinctive qualities. The defining technical and geographic factors are set forth in standards for each product, including wines, cheeses and meats. Other countries and the European Union have similar labeling systems. The European Union's protected designation of origin (PDO and PGI) system has harmonized the protection of all geographical indications and their registration. When labelling wine however, producers may still use recognized traditional terms like AOC, and are not requ ...

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 Celts and Ancient Rome, Roman eras. 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 104,000 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 Wine#Producing countries, ninth-largest wine-producing country and seventh by export market share 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 ele ...

Chambourcin
Chambourcin () is a variety of grapevine belonging to the ''Vitis'' genus in the flowering plant family Vitaceae. It is a French- American interspecific hybrid grape variety used for making wine. Its parentage is uncertain, but genetic studies show it likely includes several North American Vitis species in its background including: ''V. berlandieri'' Planch., ''V. labrusca'' L., ''V. lincecumii'' Buckley, ''V. riparia'' Michx., ''V. rupestris'' Scheele, and ''V. vinifera''. The hybrid was produced by Joannes Seyve who often used Seibel hybrids produced in the 1860s. The grape has only been available since 1963; it has a good resistance to fungal disease, and is one of the parents of the new disease resistant variety, Regent, which is increasing in popularity among German grape growers. Chambourcin is considered a very productive grape with crop yields reported ranging from 11.1 tons per hectare to 17.3 tons per hectare in a study performed by Ohio State University. Chamb ...

Müller-Thurgau
Müller-Thurgau () is a white grape variety (sp. ''Vitis vinifera'') which was created by Hermann Müller from the Swiss Canton of Thurgau in 1882 at the Geisenheim Grape Breeding Institute in Germany. It is a crossing of Riesling with Madeleine Royale. It is used to make white wine in Germany, Austria, Northern Italy, Hungary, England, Australia, the Czech Republic, Slovakia, Slovenia, New Zealand, Canada, the United States, Belgium and Japan. There are around ) cultivated worldwide, which makes Müller-Thurgau the most widely planted of the so-called "new breeds" of grape varieties created since the late 19th century. Although plantings have decreased significantly since the 1980s, as of 2019 it was still Germany's second most planted variety at 11,400 hectares and 11.4% of the total vineyard surface., Format: PDF, KBytes: 219 In 2007, the 125th anniversary was celebrated at the Geisenheim Grape Breeding Institute. Müller-Thurgau is also known as Rivaner (Austria, Germa ...
