A grape is a fruit, botanically a berry, of the deciduous woody vines of the flowering plant genus Vitis. Grapes are a non-climacteric type of fruit, generally occurring in clusters.
Cabernet Sauvignon is one of the world's most widely recognized red wine grape varieties. It is grown in nearly every major wine producing country among a diverse spectrum of climates from Australia and British Columbia, Canada to Lebanon's Beqaa Valley. Cabernet Sauvignon became internationally recognized through its prominence in Bordeaux wines, where it is often blended with Merlot and Cabernet Franc. From France and Spain, the grape spread across Europe and to the New World where it found new homes in places like California's Napa Valley, New Zealand's Hawke's Bay, South Africa's Stellenbosch region, Australia's Margaret River, McLaren Vale and Coonawarra regions, and Chile's Maipo Valley and Colchagua. For most of the 20th century, it was the world's most widely planted premium red wine grape until it was surpassed by Merlot in the 1990s. However, by 2015, Cabernet Sauvignon had once again become the most widely planted wine grape, with a total of 341,000 hectares (3,410 km2) under vine worldwide.
Aurore is a white complex hybrid grape variety produced by Albert Seibel and used for wine production mostly in the United States and Canada. Over a long lifetime Seibel produced many complex hybrid crosses of Vitis vinifera to American grapes. It is a cross of Seibel 788 and Seibel 29.
Carignan is a red grape variety of Spanish origin that is more commonly found in French wine but is widely planted throughout the western Mediterranean and around the globe. Along with Aramon, it was considered one of the main grapes responsible for France's wine lake and was a substantial producer in jug wine production in California's Central Valley but in recent years, it has been reborn as a flagship wine for many cellars in the south of France as well as in Catalonia.
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. 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.
Furmint is a white Hungarian wine grape variety that is most noted widely grown in the Tokaj-Hegyalja wine region where it is used to produce single-varietal dry wines as well as being the principal grape in the better known Tokaji dessert wines. It is also grown in the tiny Hungarian wine region of Somló. Furmint plays a similar role in the Slovakian wine region of Tokaj. It is also grown in Austria where it is known as Mosler. Smaller plantings are found in Slovenia where it is known as Šipon. The grape is also planted in Croatia & Serbia, where it is known as Moslavac. It is also found in Romania and in former republics of the Soviet Union. Furmint is a late ripening variety. For dry wines the harvest starts usually in September, however sweet wine specific harvest can start in the second half of October or even later, and is often affected by Botrytis.
Grenache or Garnacha is one of the most widely planted red wine grape varieties in the world. It ripens late, so it needs hot, dry conditions such as those found in Spain, where the grape is believed to have originated. It is also grown in the Italian island of Sardinia, the south of France, Australia, and California's Monterey AVA, Paso Robles, Santa Barbara County and San Joaquin Valley.
The Muscat family of grapes includes over 200 grape varieties belonging to the Vitis vinifera species that have been used in wine production and as raisin and table grapes around the globe for many centuries. Their colors range from white, to yellow, to pink to near black. Muscat grapes and wines almost always have a pronounced floral aroma. The breadth and number of varieties of Muscat suggest that it is perhaps the oldest domesticated grape variety, and there are theories that most families within the Vitis vinifera grape variety are descended from the Muscat variety.
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.
Pedro Ximénez is the name of a white Spanish wine grape variety grown in several Spanish wine regions but most notably in the denominación de origen (DO) of Montilla-Moriles. Here it is used to produce a varietal wine, an intensely sweet, dark, dessert sherry. It is made by drying the grapes under the hot sun, concentrating the sweetness, which are then used to create a thick, black liquid with a strong taste of raisins and molasses that is fortified and aged in solera.
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 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.
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).
Millerandage is a potential viticultural hazard problem in which grape bunches contain berries that differ greatly in size and, most importantly, maturity. Its most common cause is cold, rainy or otherwise bad weather during the flowering stage of the vines though other factors, such as boron deficiency or fanleaf degeneration, may also play a role.
Muscat Blanc à Petits Grains is a white wine grape of Greek origin that is a member of the Muscat family of Vitis vinifera. Its name comes from its characteristic small berry size and tight clusters. It is known under a variety of local names such as Moscato bianco, Muscat blanc, Muscat Canelli, Muscat de Frontignan, Muscat de Lunel, Muscat d'Alsace, Muskateller, Moscatel de Grano Menudo, Moscatel rosé and Sárgamuskotály.
The annual growth cycle of grapevines is the process that takes place in the vineyard each year, beginning with bud break in the spring and culminating in leaf fall in autumn followed by winter dormancy. From a winemaking perspective, each step in the process plays a vital role in the development of grapes with ideal characteristics for making wine. Viticulturalists and vineyard managers monitor the effect of climate, vine disease and pests in facilitating or impeding the vine's progression from bud break, flowering, fruit set, veraison, harvesting, leaf fall and dormancy-reacting if need be with the use of viticultural practices like canopy management, irrigation, vine training and the use of agrochemicals. The stages of the annual growth cycle usually become observable within the first year of a vine's life. The amount of time spent at each stage of the growth cycle depends on a number of factors-most notably the type of climate and the characteristics of the grape variety.
The acids in wine are an important component in both winemaking and the finished product of wine. They are present in both grapes and wine, having direct influences on the color, balance and taste of the wine as well as the growth and vitality of yeast during fermentation and protecting the wine from bacteria. The measure of the amount of acidity in wine is known as the “titratable acidity” or “total acidity”, which refers to the test that yields the total of all acids present, while strength of acidity is measured according to pH, with most wines having a pH between 2.9 and 3.9. Generally, the lower the pH, the higher the acidity in the wine. There is no direct connection between total acidity and pH. In wine tasting, the term “acidity” refers to the fresh, tart and sour attributes of the wine which are evaluated in relation to how well the acidity balances out the sweetness and bitter components of the wine such as tannins. Three primary acids are found in wine grapes: tartaric, malic, and citric acids. During the course of winemaking and in the finished wines, acetic, butyric, lactic, and succinic acids can play significant roles. Most of the acids involved with wine are fixed acids with the notable exception of acetic acid, mostly found in vinegar, which is volatile and can contribute to the wine fault known as volatile acidity. Sometimes, additional acids, such as ascorbic, sorbic and sulfurous acids, are used in winemaking.
This glossary of viticultural terms list some of terms and definitions involved in growing grapes for use in winemaking.
In viticulture, ripeness is the completion of the ripening process of wine grapes on the vine which signals the beginning of harvest. What exactly constitutes ripeness will vary depending on what style of wine is being produced and what the winemaker and viticulturist personally believe constitutes ripeness. Once the grapes are harvested, the physical and chemical components of the grape which will influence a wine's quality are essentially set so determining the optimal moment of ripeness for harvest may be considered the most crucial decision in winemaking.
Calitor or Calitor noir is a red French wine grape variety. It was previously widely cultivated in southern France, in particular in Provence, but is now very rare, almost extinct. Historically used as mainly a blending variety, Calitor gives high yields and produces a light-bodied and lightly colored wine. When grown on hillside sites, it can give a wine of character.
Granada is a Spanish Denominación de Origen Protegida (DOP) for wines in the province of Granada, Andalusia, Spain, extending over 168 different municipalities. There is also sub-zone known as "Contraviesa-Alpujarras", covering another 13 municipalities in the Alpujarras mountains. Granada achieved Vino de Calidad status in 2009, and Denominación de Origen status in 2018.
