Clairette Precoce
Verdesse is a white French wine grape variety grown primarily in the Bugey AOC of eastern France (though it is not currently permitted in the AOC wine).P. Saunders ''Wine Label Language'' pp. 109 Firefly Books 2004 J. Robinson ''Jancis Robinson's Guide to Wine Grapes'' pg 195 Oxford University Press 1996 It is also permitted under the Vin de Savoie AOC for wines produced in the Isère department up to a maximum allowance of 10%.Vino Files Jura and Savoie Accessed: July 4th, 2012 Ampelographers believe that the variety is likely very old and originated along the Drac and Grésivaudan valleys in Isère.Vitis Ampelography pages 'Verdesse'' (French) Accessed: July 4th, 2012 Viticulture Verdesse tends to thrive in clay and limestone slopes. It has a high tolerance to botrytis but can be very susceptible to powdery and downy mildew. The grape tends to form small to medium, compact clusters that take on a conical shape with often a side-wing cluster. The berries tend to vary from g ...

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] |
Downy Mildew
Downy mildew refers to any of several types of oomycete microbes that are obligate parasites of plants. Downy mildews exclusively belong to the Peronosporaceae family. In commercial agriculture, they are a particular problem for growers of crucifers, grapes and vegetables that grow on vines. The prime example is ''Peronospora farinosa'' featured in NCBI-Taxonomy and HYP3. This pathogen does not produce survival structures in the northern states of the United States, and overwinters as live mildew colonies in Gulf Coast states. It progresses northward with cucurbit production each spring. Yield loss associated with downy mildew is most likely related to soft rots that occur after plant canopies collapse and sunburn occurs on fruit. Cucurbit downy mildew only affects leaves of cucurbit plants. Symptoms Initial symptoms include large, angular or blocky, yellow areas visible on the upper surface. As lesions mature, they expand rapidly and turn brown. The under surface of infected ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mondeuse Blanche
Mondeuse blanche is a variety of white grape almost exclusively found in and around the Savoy wine, Savoy (Savoie) wine region in France. With just of plantations in 1999, it leads a dwindling existence and is used primarily in the VDQS wine Bugey VDQS, Bugey and the Appellation d'origine contrôlée, AOC Vin de Savoie. Related grapes DNA typing has established that Mondeuse blanche is the mother of the Syrah grape, with Dureza being the father. Despite their similarity in names, Mondeuse blanche is not closely related to Mondeuse noire, or Mondeuse gris. Grapes just called Mondeuse are usually Mondeuse noire rather than Mondeuse blanche. In the 20th century, ampelographers Louis Levadoux and (decades later) Linda Bisson categorized Mondeuse blanche as a member of the Peloursin eco-geogroup along with Bia blanc, Béclan, Dureza, Exbrayat, Durif, Jacquère, Joubertin, Peloursin, Servanin and Verdesse.J.

Jacquère
Jacquère is a variety (botany), variety of white grape found primarily in the Savoy wine region of France. It is a high-yielding vine variety which is used to produce lightly scented, refreshing and gently aromatic dry white wine, such as Vin de Savoie. Jacquère is the grape used in Apremont, Savoie, Apremont wines and is the usual wine paired with cheese fondue (a dish from the same region). It is also found in Bugey wines. Furthermore, Jacquère has been grown in some Condrieu vineyards, but it is officially not allowed to be used in Condrieu ''Appellation d'Origine Contrôlée'' wine. After increased plantings in the 1980s, it has remained at a level of about in France since the 1990s. Relationship to other grapes Gouais blanc has been secured as one of its parents, but the other is unknown. Jacquère is thought to be of French origin.

Durif
Durif is a variety of red wine grape primarily grown in Australia, California, France, and Israel. Since the end of the 20th century, wineries located in Washington's Yakima River Valley, Maryland, Arizona, Texas, West Virginia, Chile, Mexico's Baja California Peninsula, and Ontario's Niagara Peninsula have also produced wines from Durif grapes. It is the main grape known in the U.S. and Israel as Petite Sirah, with over 90% of the California plantings labeled "Petite Sirah" being Durif grapes; the U.S. Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) recognizes "Durif" and "Petite Sirah" as synonyms for the same grape.PS I Love YoPetite Sirah Timeline It produces tannic wines with a spicy, plummy flavour. The grape originated as a cross of Syrah pollen germinating a Peloursin plant. On some occasions, Peloursin and Syrah vines may be called Petite Sirah, usually because the varieties are extremely difficult to distinguish in old age. History In the 1860s the Fren ...

Dureza
Dureza is a dark-skinned French wine grape variety from the Ardèche department of south central France in the Rhône-Alpes region. The grape is most widely known for being the father vine of Syrah—a discovery that confirmed that the Syrah vine was native to France and not introduced to the country from Persia, Sicily, Egypt or elsewhere, as had been speculated.J. Robinson, J. Harding and J. Vouillamoz ''Wine Grapes - A complete guide to 1,368 vine varieties, including their origins and flavours'' pgs XXVII, 316, 528 & 1023, Allen Lane 2012 Dureza was historically used for production of red wine, but is hardly grown any more and is not part of the list of the allowed grape varieties of any French ''Appellation d'origine contrôlée'' wine, though it can be produced under some ''vin de pays''. There were only 11 hectares planted to Dureza in the late 1970s: by 1988 only one hectare remained. However, since the variety's relationship to Syrah was revealed, interest in Dureza has ...

Bia Blanc
Bia blanc is a white French wine grape variety that is no longer commercially cultivated for wine production with only a few plantings existing worldwide in viticultural archives and experimental vineyards. The exact origins of Bia blanc are not yet known though ampelographers have noted that the grapevine shares some morphological similarities to the red Isère grape Peloursin, one of the parent varieties to Petite Sirah (Durif). Eco-geogroup In the 20th century, ampelographers Louis Levadoux and (decades later) Linda Bisson categorized Bia blanc as a member of the Pelorsien eco-geogroup along with Durif, Béclan, Dureza, Exbrayat, Jacquère, Joubertin, Mondeuse blanche, Peloursin, Servanin and Verdesse. Synonyms Over the years, Bia blanc has been known under a variety of synonyms including: Bear, Beard and Biard.Vitis International Variety Catalogue The Vitis International Variety Catalogue (VIVC) is a database of various species and varieties/cultivars of grapevine, the gen ...

Ellipsoid
An ellipsoid is a surface that may be obtained from a sphere by deforming it by means of directional scalings, or more generally, of an affine transformation. An ellipsoid is a quadric surface; that is, a surface that may be defined as the zero set of a polynomial of degree two in three variables. Among quadric surfaces, an ellipsoid is characterized by either of the two following properties. Every planar cross section is either an ellipse, or is empty, or is reduced to a single point (this explains the name, meaning "ellipse-like"). It is bounded, which means that it may be enclosed in a sufficiently large sphere. An ellipsoid has three pairwise perpendicular axes of symmetry which intersect at a center of symmetry, called the center of the ellipsoid. The line segments that are delimited on the axes of symmetry by the ellipsoid are called the ''principal axes'', or simply axes of the ellipsoid. If the three axes have different lengths, the figure is a triaxial ellipsoid (r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
