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.
Noble rot is the beneficial form of a grey fungus, Botrytis cinerea, affecting wine grapes. Infestation by Botrytis requires moist conditions. If the weather stays wet, the damaging form, "grey rot", can destroy crops of grapes. Grapes typically become infected with Botrytis when they are ripe. If they are then exposed to drier conditions and become partially raisined, this form of infection is known as noble rot. Grapes picked at a certain point during infestation can produce particularly fine and concentrated sweet wine. Wines produced by this method are known as botrytized wines.
Late harvest wine is wine made from grapes left on the vine longer than usual. Late harvest is usually an indication of a sweet dessert wine, such as late harvest Riesling. Late harvest grapes are often more similar to raisins, but have been naturally dehydrated while on the vine.
Blaufränkisch is a dark-skinned variety of grape used for red wine. Blaufränkisch, which is a late-ripening variety, produces red wines which are typically rich in tannin and may exhibit a pronounced spicy character.
Dornfelder is a dark-skinned variety of grape of German origin used for red wine. It was created by August Herold (1902–1973) at the grape breeding institute in Weinsberg in the Württemberg region in 1955. Herold crossed the grape varieties Helfensteiner and Heroldrebe, the latter which bears his name, to create Dornfelder. Helfensteiner and Heroldrebe were both crosses created some decades earlier by Herold. Dornfelder received varietal protection and was released for cultivation in 1979. It was named in honor of Immanuel August Ludwig Dornfeld (1796–1869), a senior civil servant who was instrumental in creating the viticultural school in Weinsberg.
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 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 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.
Sémillon is a golden-skinned grape used to make dry and sweet white wines, mostly in France and Australia. Its thin skin and susceptibility to botrytis make it dominate the sweet wine region Sauternes AOC and Barsac AOC.
Agiorgitiko is a red Greek wine grape variety that, as of 2012, was the most widely planted red grape variety in Greece, ahead of Xynomavro. The grape has traditionally been grown in the Nemea region of the Peloponnese but can be found throughout the country including Attikí (Attica) and Makedonía (Macedonia).
Regent is a dark-skinned inter-specific hybrid grape variety, used for making wine. It has both European and American vine species in its pedigree and a broad resistance against the most significant fungal diseases which affect grapes, such as downy mildew.
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.
Zéta is a Hungarian wine grape, a crossing of Furmint and Bouvier. It was introduced to the Tokaj-Hegyalja wine region of Hungary in 1951 and authorized for production in 1990. Previously known as Oremus, its name was changed to Zéta in 1999. Its main asset is a particular aptitude for high sugar concentrations, early ripening and susceptibility for botrytis.
Marselan is a red French wine grape variety that is a cross between Cabernet Sauvignon and Grenache. It was first bred in 1961 by Paul Truel near the French town of Marseillan. The vine is grown mostly in the Languedoc wine region with some plantings in the Northern Coast of California. It has also become very popular in China. The grape usually produces a medium body red wine.

Cabernet Cortis is a dark-skinned grape variety used for wine. It was bred in 1982 by Norbert Becker at the viticultural institute in Freiburg, Germany as part of a programme searching for disease-resistant grape varieties. It received German varietal protection in 2003.
Băbească neagră is a red Moldovan and Romanian wine grape variety. It is cultivated in the south of Moldova and in Romania in the regions of Moldavia, Dobruja and Wallachia, making it the second most widely planted grape variety in Romania. It is also found in Ukraine and New York, United States, where the grape is known as Sereksiya Charni.
Œillade noire is a red French wine grape variety that has been historically grown in the Languedoc and Provence wine region but it is now close to extinction. The grape is often confused for the Rhone wine grape Cinsault which is known under the synonym œillade noire when it is sold as a table grape. It was also once thought to be a color mutation of Picardan which is known as œillade blanche and share several similar synonyms to œillade noire. However the grape has no known relation to both Cinsault and Picardan.
Arrouya noir is a red French wine grape variety grown in the Jurançon region of Southwest France. The grape has a long history in the region, growing in the Pyrénées-Atlantiques since at least the late 18th century. Ampelographers believe that Arrouya noir has some genetic relationship with Camaraou noir, Fer and Petit Courbu though the exact nature of those relationships is not yet known. The variety also shares some similarities in morphology with Cabernet Franc and until the late 19th century was often confused for the Loire and Bordeaux wine grape, especially in the Basses-Pyrénées and Hautes-Pyrénées region.
Luglienga is a white Italian wine and table grape variety that is grown across Europe. The grape has a long history of use, dating back to at least the 14th century in Piedmont but is today most seen a table grape that is occasionally used for home winemaking.
Verdello is a white Italian wine grape variety that is grown mostly in the Umbria region of central Italy where it plays a minor role as a blending grape in several Denominazione di Origine Controllata (DOC) wines, including Orvieto. Despite similarities in their names, the Italian Verdello grape has no close genetic relationship with the Portuguese wine grape Verdelho that is grown on the islands of Madeira and Azores. However, like the Portuguese grape, Verdello's name likely comes from the dark green color of its berries before veraison.
Bigolona is a white Italian wine grape variety from the Valpolicella region of northeast Italy where it has been growing since at least the early 19th century. The wine has traditionally been used in the production of late harvest and botrytized dessert wines with the grape's synonym Smarzirola being derived from the Italian marcire meaning "to rot".
