Chardonnay is a green-skinned grape variety used in the production of white wine. The variety originated in the Burgundy wine region of eastern France, but is now grown wherever wine is produced, from England to New Zealand. For new and developing wine regions, growing Chardonnay is seen as a 'rite of passage' and an easy entry into the international wine market.
Sauvignon blanc is a green-skinned grape variety that originates from the Bordeaux region of France. The grape most likely gets its name from the French words sauvage ("wild") and blanc ("white") due to its early origins as an indigenous grape in South West France. It is possibly a descendant of Savagnin. Sauvignon blanc is planted in many of the world's wine regions, producing a crisp, dry, and refreshing white varietal wine. The grape is also a component of the famous dessert wines from Sauternes and Barsac. Sauvignon blanc is widely cultivated in France, Chile, Romania, Canada, Australia, New Zealand, South Africa, Bulgaria, the states of Oregon, Washington, and California in the US. Some New World Sauvignon blancs, particularly from California, may also be called "Fumé Blanc", a marketing term coined by Robert Mondavi in reference to Pouilly-Fumé.
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.
Gewürztraminer is an aromatic wine grape variety, used in white wines, and performs best in cooler climates. In English, it is sometimes referred to colloquially as Gewürz, and in English and French it is written Gewurztraminer. Gewürztraminer is a variety with a pink to red skin colour, which makes it a "white wine grape" as opposed to the blue to black-skinned varieties commonly referred to as "red wine grapes". The variety has high natural sugar and the wines are white and usually off-dry, with a flamboyant bouquet of lychees. Indeed, Gewürztraminer and lychees share the same aroma compounds. Dry Gewürztraminers may also have aromas of roses, passion fruit and floral notes. It is not uncommon to notice some spritz.
Petit Verdot is a variety of red wine grape, principally used in classic Bordeaux blends. It ripens much later than the other varieties in Bordeaux, often too late, so it fell out of favour in its home region. When it does ripen it adds tannin, colour and flavour, in small amounts, to the blend. Petit verdot has attracted attention among winemakers in the New World, where it ripens more reliably and has been made into single varietal wine. It is also useful in 'stiffening' the mid palate of Cabernet Sauvignon blends.
Trousseau or Trousseau Noir, also known as Bastardo and Merenzao, is an old variety of red wine grape originating in eastern France. It is grown in small amounts in many parts of Western Europe; the largest plantations are today found in Portugal, where most famously it is used in port wine. It makes deep cherry red wines with high alcohol and high, sour candy acidity, and flavours of red berry fruits, often complemented - depending on production - by a jerky nose and an organic, mossy minerality.
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.
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).
Hybrid grapes are grape varieties that are the product of a crossing of two or more Vitis species. This is in contrast to crossings between grape varieties of the same species, typically Vitis vinifera, the European grapevine. Hybrid grapes are also referred to as inter-specific crossings or "Modern Varieties." Due to their often excellent tolerance to powdery mildew, other fungal diseases, nematodes, and phylloxera, hybrid varieties have, to some extent, become a renewed focus for European breeding programs. The recently developed varieties, Rondo, and Regent are examples of newer hybrid grape varieties for European viticulturalists. Several North American breeding programs, such as those at Cornell and the University of Minnesota, focus exclusively on hybrid grapes, with active and successful programs, having created hundreds if not thousands of new varieties.
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.
New Zealand wine is produced in several of its distinct winegrowing regions. As an island country in the South Pacific Ocean, New Zealand has a largely maritime climate, although its elongated geography produces considerable regional variation from north to south. Like many other New World wines, New Zealand wine is usually produced and labelled as single varietal wines, or if blended, winemakers list the varietal components on the label. New Zealand is best known for its Marlborough Sauvignon Blanc, and more recently its dense, concentrated Pinot Noir from Marlborough, Martinborough and Central Otago.
Morio Muscat is a white wine grape that was created by viticulturalist Peter Morio at the Geilweilerhof Institute for Grape Breeding in the Palatinate in 1928. He claimed to have crossed the varieties Silvaner and Pinot blanc, but based on the variety's properties it has been speculated that he actually crossed Silvaner and Muscat Blanc à Petits Grains. But so far this speculation has yet to be conclusively proven. The grape is highly aromatic with a "grapey" characteristic reminiscent of Muscat grape varieties. The grape is rarely used for varietal wines because it requires a high level of ripeness to avoid producing wine with a "mousey" flavor, a coarse texture and overabundance of acidity.
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.
Petit Meslier is a rare white wine grape that is a minor component of some Champagne blends. It is valued for its ability to retain acidity even in hot vintages. In the very rare cases where it is not blended, it makes crisp wines tasting of apples. The Traminer family of grapes can be difficult to grow, with poor disease resistance and low yields.
Optima is a white wine grape that was created by viticulturalist Peter Morio at the Geilweilerhof Institute for Grape Breeding in the Palatinate in 1930. Morio crossed a Riesling x Silvaner cross with Müller-Thurgau. The Riesling x Silvaner is sometimes mentioned as Rieslaner, but more often just as "a Riesling x Silvaner". Due to the random element of genetic recombination involved in sexual reproduction of plants, no two crosses of the same parent grape varieties will be identical, so there is a difference between the Riesling x Silvaner cross Rieslaner, and each other such cross.
Biancame is a white Italian wine grape variety that is grown in the Marche and Emilia-Romagna regions of Italy. Here it is an important component in the Denominazione di origine controllata (DOC) wines of Bianchello del Metauro and Colli di Rimini.
Incrocio Manzoni or Manzoni grapes is a family of grape varieties named after Professor Luigi Manzoni (1888-1968) of Italy's oldest school of oenology located in Conegliano, in the Veneto region. Manzoni created the new grape varieties by selecting, crossing and grafting vines from various vineyards during the 1920s and 1930s. The family includes both white and red grape varieties. Although most Manzonis are grown in northeastern Italy, they are mainly grown in the Piave area of Province of Treviso and are only now starting to be sold commercially in Europe and the United States.
Landot noir is a red hybrid grape variety that is a crossing of Landal and Villard blanc. Created after a series of trials between 1929-1949, the grape was introduced to Canada and the United States in the 1950s and today can be found in Quebec as well as New Hampshire where a varietal is produced by Jewell Towne Vineyards.
Cabernet blanc is a white German and Swiss wine grape variety that is a crossing of the French wine grape Cabernet Sauvignon and Regent. The grape was bred by Swiss grape breeder Valentin Blattner in 1991. Cabernet blanc has strong resistance to most grape disease including botrytis bunch rot, downy and powdery mildew and tends to produce loose clusters of small, thick-skinned grape berries which can hang on the vine late into the harvest season to produce dessert wines. Today the grape is found primarily in the Palatinate wine region of Germany with some experimental plantings in Spain and the Netherlands. In France, in the Languedoc, Domaine La Colombette is heavily investing in PIWI grapes. Amongst others the Cabernet Blanc in their cuvée "Au Creux du Nid", is gaining wide acclaim.
Muscat bleu is a red Swiss wine and table grape variety that is a hybrid of Garnier 15-6 and Perle noire. The grape was developed in Peissy in the Canton of Geneva by Swiss grape breeder Charles Garnier in the 1930s. Today the grape is used as both a table grape and for winemaking, producing wines that Master of Wine Jancis Robinson describe as "soft and grapey". Outside Switzerland some plantings of Muscat bleu can also be found in Belgium.
