Riesling is a white grape variety that originated in the Rhine region. Riesling is an aromatic grape variety displaying flowery, almost perfumed, aromas as well as high acidity. It is used to make dry, semi-sweet, sweet, and sparkling white wines. Riesling wines are usually varietally pure and are seldom oaked. As of 2004, Riesling was estimated to be the world's 20th most grown variety at 48,700 hectares, but in terms of importance for quality wines, it is usually included in the "top three" white wine varieties together with Chardonnay and Sauvignon blanc. Riesling is a variety that is highly "terroir-expressive", meaning that the character of Riesling wines is greatly influenced by the wine's place of origin.
Roussanne is a white wine grape grown originally in the Rhône wine region in France, where it is often blended with Marsanne. It is the only other white variety, besides Marsanne, allowed in the northern Rhône appellations of Crozes-Hermitage AOC, Hermitage AOC and Saint-Joseph AOC. In the southern Rhône appellation of Châteauneuf-du-Pape AOC it is one of six white grapes allowed, where it may be blended into red wines. Roussanne is also planted in various wine-growing regions of the New World, such as California, Washington, Texas, South Africa and Australia as well as European regions such as Crete, Tuscany and Spain.
Viticulture, viniculture, or winegrowing is the cultivation and harvesting of grapes. It is a branch of the science of horticulture. While the native territory of Vitis vinifera, the common grape vine, ranges from Western Europe to the Persian shores of the Caspian Sea, the vine has demonstrated high levels of adaptability to new environments, hence viticulture can be found on every continent except Antarctica.
Grüner VeltlinerGerman:[ˈɡʁyːnɐfɛltˈliːnɐ] ) is a white wine grape variety grown primarily in Austria, Hungary, Slovakia, and the Czech Republic. The leaves of the grape vine are five-lobed with bunches that are long but compact, and deep green grapes that ripen in mid-late October in the Northern Hemisphere.
Müller-Thurgau is a white grape variety 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 22,201 hectares ) 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. In 2007, the 125th anniversary was celebrated at the Geisenheim Grape Breeding Institute. Müller-Thurgau is also known as Rivaner, Riesling x Sylvaner, Riesling-Sylvaner, Rizvanec (Slovenia) and Rizlingszilváni (Hungary).
Mourvèdre is a red wine grape variety grown in many regions around the world including the Rhône and Provence regions of France, the Valencia and Jumilla, Bullas and Yecla denominaciones de origen (DOs) of Spain, as well as the Balearic Islands, California and Washington and the Australian regions of South Australia and New South Wales, plus South Africa. In addition to making red varietal wines, Mourvèdre is a prominent component in "GSM" blends. The variety is also used to make rosé and port-style fortified wines.
Catawba is a red American grape variety used for wine as well as juice, jams and jellies. The grape can have a pronounced musky or "foxy" flavor. Grown predominantly on the East Coast of the United States, this purplish-red grape is a likely a hybrid of the native American Vitis labrusca and the Vitis vinifera cultivar Semillon. Its exact origins are unclear but it seems to have originated somewhere on the East coast from the Carolinas to Maryland.
Vidal blanc is a white hybrid grape variety produced from the Vitis vinifera variety Ugni blanc and another hybrid variety, Rayon d'Or. It is a very winter-hardy variety that manages to produce high sugar levels in cold climates with moderate to high acidity.
Chelois is a variety of hybrid grape used in the production of red wines. The fruit are small blue-black berries, which appear in compact, medium-sized clusters. Chelois is among the less hardy hybrids of red-wine grapes.
Vitis amurensis, the Amur grape, is a species of grape native to the Asian continent. Its name comes from the Amur Valley in Russia and China.
Rondo is a dark-skinned grape variety, used for making red wine. It is a hybrid grape or inter-specific crossing. It was created in 1964 by Professor Vilém Kraus in then-Czechoslovakia by crossing the varieties Zarya Severa and St. Laurent. He offered it to Dr. Helmut Becker (1927-1990) of the Geisenheim Grape Breeding Institute who conducted further work on it, which explains why the grape is known under a Geisenheim designation. The variety was first planted for research and later in bigger scale in the mid 1980s by Thomas Walk Vineyard in Ireland under the name Amurensis Walk; it was named Rondo in 1997.
Ehrenfelser is a white wine grape variety of German origin. It was created by Dr. Heinrich Birk (1898-1973) at the Geisenheim Grape Breeding Institute in 1929, by crossing Riesling with what was thought at the time to be Silvaner, but DNA markers have since indicated it was the Alsace variety Knipperlé.
The Kerner grape is an aromatic white grape variety. It was bred in 1929 by August Herold by crossing Trollinger and Riesling. Herold was working at a plant breeding station in Lauffen in the Württemberg region of Germany. This station belonged to a state breeding institute headquartered in Weinsberg. It received varietal protection and was released for general cultivation in 1969.
Solaris is a variety of grape used for white wine. It was created in 1975 at the grape breeding institute in Freiburg, Germany by Norbert Becker.
Nova Scotia wine is Canadian wine produced in the Canadian province of Nova Scotia. Nova Scotia's wineries are primarily organized under the Wine Association of Nova Scotia, though not all wineries are members. The industry began in the late 1970s with the original Grand Pré Winery in the Annapolis Valley of Nova Scotia.
Marquette is an inter-species hybrid red wine grape variety. It was developed at the University of Minnesota as part of its grape breeding program, and is a cross between two other hybrids, MN 1094 and Ravat 262. Marquette was introduced in 2006 and has good resistance to downy mildew, powdery mildew, and black rot, as well as being cold hardy.
Ravat blanc is a white hybrid grape variety that is a crossing of Chardonnay and a Seibel grape. While the Vitis International Variety Catalogue (VIVC) maintained by the Geilweilerhof Institute for Grape Breeding list Seibel 5474 as the second parent, Master of Wine Jancis Robinson notes that other authors list Seibel 8724 as the parent. The grape is often confused with the white hybrid grape Vignoles that is often called just Ravat.
Grisa nera is a red Italian wine grape variety that is grown in the Piedmont wine region of northwest Italy where it is used in both winemaking and as a table grape. The grape is most often used as a minor blending component with wines made from Barbera, Neretta Cuneese and Plassa.

He received his doctorate in this subject in 1929. At this time he was already two years as clerk at the Geisenheim Research Center at the Institute of vines finishing as an assistant to Professor F. Muth. 1939 he became head of the Reichs-Rebenzuchtstation. He had to quit a year later because of his compulsory military service. 1945 Birk returned and devoted himself in postwar reconstruction.
