In viticulture, there are several levels of regional climates that are used to describe the terroir or immutable characteristics of an area. These levels can be as broad as a macroclimate which includes entire wine regions or as small as a microclimate which includes the unique environment around an individual grapevine. In the middle is the mesoclimate which usually describes the characteristics of a particular vineyard site.
A vineyard is a plantation of grape-bearing vines, grown mainly for winemaking, but also raisins, table grapes and non-alcoholic grape juice. The science, practice and study of vineyard production is known as viticulture. Vineyards are often characterised by their terroir, a French term loosely translating as "a sense of place" that refers to the specific geographical and geological characteristics of grapevine plantations, which may be imparted to the wine itself.
Viticulture 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.
Terroir is a French term used to describe the environmental factors that affect a crop's phenotype, including unique environment contexts, farming practices and a crop's specific growth habitat. Collectively, these contextual characteristics are said to have a character; terroir also refers to this character.
Washington wine is a wine produced from grape varieties grown in the U.S. state of Washington. Washington ranks second in the United States in the production of wine. By 2017, the state had over 55,000 acres (220 km2) of vineyards, a harvest of 229,000 short tons (208,000 t) of grapes, and exports going to over 40 countries around the world from the 940+ wineries located in the state. While there are some viticultural activities in the cooler, wetter western half of the state, the majority (99.9%) of wine grape production takes place in the shrub-steppe eastern half. The rain shadow of the Cascade Range leaves the Columbia River Basin with around 8 inches (200 mm) of annual rain fall, making irrigation and water rights of paramount interest to the Washington wine industry. Viticulture in the state is also influenced by long sunlight hours and consistent temperatures.
The Mendocino County wine is an appellation that designates wine made from grapes grown mostly in Mendocino County, California. The region is part of the larger North Coast AVA and one of California's largest and most climatically diverse wine growing regions. Mendocino County is one of the northernmost commercial wine grape regions in the state with two distinct climate zones separated by the Mendocino Range. Ten American Viticultural Areas have been designated within Mendocino County. Mendocino is one of the leading wine growing regions for organically produced wine grapes. Nearly 25% of the acreage in Mendocino County is grown organically. In 2004, the residents of the county voted to become the first GMO-free county in the United States in an initiative that was supported by many of the county's largest wineries. The county's widespread focus on organic viticulture has inspired journalists to describe it as "California's organic wine Mecca".
Vietnamese wine is wine produced in Vietnam. The area was first cultivated for viticulture during the French colonial rule of the region in the late 19th century. The region's tropical climate was ill-suited for the type of Vitis vinifera that the French colonists were used to and the wine industry turned its attention to fruit wine production. The late 20th century saw a renewed focus on the development of Vitis vinifera with the assistance of flying winemakers from regions like Australia. In 1995, a joint venture with Australian winemakers started an aggressive planting scheme to reintroduce international grape varieties like Cabernet Sauvignon and Chardonnay to land that was until recently littered with landmines left over from the Vietnam War.
The modern Indian Wine market is small but growing; annual per capita consumption of wine in the country is a mere 9 milliliters, approximately 1/8000th that of France. The main reason for this can be attributed to the fact that Indians preference for hard liquor and beer boasts nearly 98% of market share whereas wine with low ABV only has 2% market share. The viticulture in India has a long history dating back to the time of the Indus Valley civilization when grapevines were believed to have been introduced from Persia. Winemaking has existed throughout most of India's history but was particularly encouraged during the time of the Portuguese and British colonization of the subcontinent. The end of the 19th century saw the phylloxera louse take its toll on the Indian wine industry followed by religious and public opinion moving towards the prohibition. Following the country's independence from the British Empire, the government encouraged vineyards to convert to table grape and raisin production. In the 1980s and 1990s, a revival in the Indian wine industry took place as international influences and the growing middle class started increasing demand for the beverage. By the turn of the 21st century, demand was increasing at a rate of 20-30% a year. The city of Nashik in the state of Maharashtra is called the "Wine Capital of India."
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.
In viticulture, the canopy of a grapevine includes the parts of the vine visible aboveground - the trunk, cordon, stems, leaves, flowers, and fruit. The canopy plays a key role in light energy capture via photosynthesis, water use as regulated by transpiration, and microclimate of ripening grapes. Canopy management is an important aspect of viticulture due to its effect on grape yields, quality, vigor, and the prevention of grape diseases. Various viticulture problems, such as uneven grape ripening, sunburn, and frost damage, can be addressed by skillful canopy management. In addition to pruning and leaf trim, the canopy is often trained on trellis systems to guide its growth and assist in access for ongoing management and harvest.
Old World wine refers primarily to wine made in Europe but can also include other regions of the Mediterranean basin with long histories of winemaking such as North Africa and the Near East. The phrase is often used in contrast to "New World wine" which refers primarily to wines from New World wine regions such as the United States, Australia, South America and South Africa. The term "Old World wine" does not refer to a homogeneous style with "Old World wine regions" like Austria, France, Georgia, Italy, Portugal, and Spain each making vastly different styles of wine even within their own borders. Rather, the term is used to describe general differences in viticulture and winemaking philosophies between the Old World regions where tradition and the role of terroir lead versus the New World where science and the role of the winemaker are more often emphasized. In recent times, the globalization of wine and advent of flying winemakers have lessened the distinction between the two terms with winemakers in one region being able to produce wines that can display the traits of the other region—i.e. an "Old World style" wine being produced in a New World wine region like California or Chile and vice versa.
Precision viticulture is precision farming applied to optimize vineyard performance, in particular maximizing grape yield and quality while minimizing environmental impacts and risk. This is accomplished by measuring local variation in factors that influence grape yield and quality and applying appropriate viticulture management practices. Precision viticulture is based on the premise that high in-field variability for factors that affect vine growth and grape ripening warrants intensive management customized according to local conditions. Precision viticulture depends on new and emerging technologies such as global positioning systems (GPS), meteorologic and other environmental sensors, satellite and airborne remote sensing, and geographic information systems (GIS) to assess and respond to variability.
Croatian wine has a history dating back to the Ancient Greek settlers, and their wine production on the southern Dalmatian islands of Vis, Hvar and Korčula some 2,500 years ago. Like other old world wine producers, many traditional grape varieties still survive in Croatia, perfectly suited to their local wine hills. Modern wine-production methods have taken over in the larger wineries and EU-style wine regulations have been adopted, guaranteeing the quality of the wine.
This glossary of viticultural terms list some of terms and definitions involved in growing grapes for use in winemaking.
Brazil is the third-largest producer of wine in South America, behind Argentina and Chile; production in 2018 was 3.1 million hectolitres (82,000,000 US gal), slightly more than New Zealand. In 2019, Brazil was the 15th largest wine producer in the world. A substantial area is devoted to viticulture: 82,000 hectares in 2018, though much of it produces table grapes rather than wine grapes.
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.
Irrigation in viticulture is the process of applying extra water in the cultivation of grapevines. It is considered both controversial and essential to wine production. In the physiology of the grapevine, the amount of available water affects photosynthesis and hence growth, as well as the development of grape berries. While climate and humidity play important roles, a typical grape vine needs 25-35 inches of water a year, occurring during the spring and summer months of the growing season, to avoid stress. A vine that does not receive the necessary amount of water will have its growth altered in a number of ways; some effects of water stress are considered desirable by wine grape growers.
In viticulture, the climates of wine regions are categorised based on the overall characteristics of the area's climate during the growing season. While variations in macroclimate are acknowledged, the climates of most wine regions are categorised as being part of a Mediterranean, maritime or continental climate. The majority of the world's premium wine production takes place in one of these three climate categories in locations between the 30th parallel and 50th parallel in both the northern and southern hemisphere. While viticulture does exist in some tropical climates, most notably Brazil, the amount of quality wine production in those areas is so small that the climate effect has not been as extensively studied as other categories.
The use of vine training systems in viticulture is aimed primarily to assist in canopy management with finding the balance in enough foliage to facilitate photosynthesis without excessive shading that could impede grape ripening or promote grape diseases. Additional benefits of utilizing particular training systems could be to control potential yields and to facilitate mechanization of certain vineyard tasks such as pruning, irrigation, applying pesticide or fertilizing sprays as well as harvesting the grapes.
The Hunter Valley is one of Australia's wine regions. Located in the state of New South Wales and first cultivated in the early 19th century, it was one of the first Australian wine regions. As well as Hunter Valley Sémillon, the region produces wine from a variety of grapes including Shiraz, Chardonnay, Cabernet Sauvignon and Verdelho.
The propagation of grapevines is an important consideration in commercial viticulture and winemaking. Grapevines, most of which belong to the Vitis vinifera family, produce one crop of fruit each growing season with a limited life span for individual vines. While some centenarian old vine examples of grape varieties exist, most grapevines are between the ages of 10 and 30 years. As vineyard owners seek to replant their vines, a number of techniques are available which may include planting a new cutting that has been selected by either clonal or mass (massal) selection. Vines can also be propagated by grafting a new plant vine upon existing rootstock or by layering one of the canes of an existing vine into the ground next to the vine and severing the connection when the new vine develops its own root system.
