Huglin Index
Pierre Huglin developed a bioclimatic heat index for vineyards, the Huglin heat sum index (or ''after Huglin'' respectively -warmth index or short Huglin index,) in which the temperature sum over the temperature threshold of 10 °C is calculated and then summed for all days from beginning of April to end of September. The calculation uses both the daily average temperatures and the maximum temperatures and slightly modifies the calculated total according to latitude. Each grape variety needs a certain amount of heat in order to be cultivated successfully in the long term in a given area. The calculated heat sums, which are based on data from weather stations or from climate models, differ in that they are too low compared to the actual values in the vineyards. The index does not take into account e.g. thermally favoured hillsides where temperature values may be higher by about 1.5 °C to 2 °C. Definition & Calculation The Huglin index is calculated as a product o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vineyard
A vineyard (; also ) 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. History The earliest evidence of wine production dates from between 6000 and 5000 BC. Wine making technology improved considerably with the ancient Greeks but it wasn't until the end of the Roman Empire that cultivation techniques as we know them were common throughout Europe. In medieval Europe the Church was a staunch supporter of wine, which was necessary for the celebration of the Mass. During the lengthy instability of the Middle Ages, the monasteries maintained and developed viticultural prac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cabernet Franc
Cabernet Franc is one of the major black grape varieties worldwide. It is principally grown for blending with Cabernet Sauvignon and Merlot in the Bordeaux style, but can also be vinified alone, as in the Loire's Chinon. In addition to being used in blends and produced as a varietal in Canada and the United States, it is sometimes made into ice wine in those regions. Cabernet Franc is lighter than Cabernet Sauvignon, making a bright pale red wine that contributes finesse and lends a peppery perfume to blends with more robust grapes. Depending on the growing region and style of wine, additional aromas can include tobacco, raspberry, bell pepper, cassis, and violets. Records of Cabernet Franc in Bordeaux go back to the end of the 18th century, although it was planted in Loire long before that time. DNA analysis indicates that Cabernet Franc is one of two parents of Cabernet Sauvignon, Merlot, and Carménère. History Cabernet Franc is believed to have been established in the ...

Climate Change
In common usage, climate change describes global warming—the ongoing increase in global average temperature—and its effects on Earth's climate system. Climate change in a broader sense also includes previous long-term changes to Earth's climate. The current rise in global average temperature is more rapid than previous changes, and is primarily caused by humans burning fossil fuels. Fossil fuel use, deforestation, and some agricultural and industrial practices increase greenhouse gases, notably carbon dioxide and methane. Greenhouse gases absorb some of the heat that the Earth radiates after it warms from sunlight. Larger amounts of these gases trap more heat in Earth's lower atmosphere, causing global warming. Due to climate change, deserts are expanding, while heat waves and wildfires are becoming more common. Increased warming in the Arctic has contributed to melting permafrost, glacial retreat and sea ice loss. Higher temperatures are also causing m ...

Aramon (grape)
Aramon or Aramon noir is a variety of red wine grape grown primarily in Languedoc-Roussillon in southern France. Between the late 19th century and the 1960s, it was France's most grown grape variety, but plantings of Aramon have been in continuous decline since the mid-20th century. Aramon has also been grown in Algeria, Argentina and Chile but nowhere else did it ever reach the popularity it used to have in the south of France. It is most noted for its very high productivity, and yields can reach levels as high as 400 hectolitres per hectare. The vine's resistance to oidium, phylloxera, and powdery mildew led to its reputation as workhorse grape that could be relied on by growers for dependable financial returns.J. Robinson ''Vines, Grapes & Wines'' pg 205 Mitchell Beazley 1986 However, when cropped at high yields, the resultant wines are very light red in color (but show a blue-black tinge), low in alcohol and extract and generally thin on character. Such Aramon wine is often ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carignan
Carignan (also known as Mazuelo, Bovale Grande, Cariñena, Carinyena, Samsó, Carignane, and Carignano) 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.Oz Clarke ''Encyclopedia of Grapes'' pg 58 Harcourt Books 2001 Ampelographers believe that the grape likely originated in Cariñena, Aragon and was later transplanted to Sardinia, elsewhere in Italy, France, Algeria, and much of the New World. The variety was historically a component of Rioja's red wine blend. The grape's prominence in France hit a high point in 1988 when it accounted for and was France's mo ...

Cinsaut
Cinsaut or Cinsault ( ) is a red wine grape whose heat tolerance and productivity make it important in Languedoc-Roussillon and the former French colonies of Algeria, Lebanon, and Morocco. It is often blended with grapes such as Grenache and Carignan to add softness and bouquet.Jancis Robinson, ''Vines, Grapes & Wines'' Mitchell Beazley 1986 It has many synonyms, of which perhaps the most confusing is its sale as a table grape called 'Oeillade', although it is different from the "true" Oeillade which is no longer cultivated. In South Africa, it was known as "Hermitage", hence the name of its most famous cross Pinotage. History Cinsaut appears to be an ancient variety that may have originated in the Hérault, but could equally have been brought by traders from the eastern Mediterranean. Distribution and wines Algeria Cinsaut is popular in Algeria for its drought resistance, and is used to make large volumes of wine. Australia Cinsaut is grown under a variety of names such a ...

Syrah
Syrah (), also known as Shiraz, is a dark-skinned grape variety grown throughout the world and used primarily to produce red wine. In 1999, Syrah was found to be the offspring of two obscure grapes from southeastern France, Dureza and Mondeuse Blanche. Syrah should not be confused with Petite Sirah, a cross of Syrah with Peloursin dating from 1880. The style and flavor profile of wines made from Syrah are influenced by the climate where the grapes are grown. In moderate climates (such as the northern Rhone Valley and parts of the Walla Walla AVA in Washington State), they tend to produce medium to full-bodied wines with medium-plus to high levels of tannins and notes of blackberry, mint and black pepper. In hot climates (such as Crete, and the Barossa Valley and McLaren Vale regions of Australia), Syrah is more consistently full-bodied with softer tannin, jammier fruit and spice notes of licorice, anise and earthy leather. In many regions the acidity and tannin levels of Syra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grenache
Grenache () or Garnacha () is one of the most widely planted red wine grape varieties in the world. Niels Lillelund: ''Rhône-Vinene'' p. 25, JP Bøger – JP/Politikens Forlagshus A/S, 2004. . It ripens late, so it needs hot, dry conditions such as those found in Spain, where the grape most likely originated. It is also grown in the Italian island of Sardinia, the south of France, Australia, and California's Monterey AVA and San Joaquin Valley. It is generally spicy, berry-flavored and soft on the palate and produces wine with a relatively high alcohol content, but it needs careful control of yields for best results. Characteristic flavor profiles on Grenache include red fruit flavors (raspberry and strawberry) with a subtle, white pepper spice note. Grenache wines are highly prone to oxidation, with even young examples having the potential to show browning (or "bricking") coloration that can be noticed around the rim when evaluating the wine at an angle in the glass.

Ugni Blanc
Trebbiano is an Italian wine grape, one of the most widely planted grape varieties in the world. It gives good yields, but tends to yield undistinguished wine. It can be fresh and fruity, but does not keep long. Also known as ugni blanc, it has many other names reflecting a family of local subtypes, particularly in Italy and France.Robinson, Jancis ''Vines, Grapes & Wines'' Mitchell Beazley 1986 Its high acidity makes it important in Cognac and Armagnac productions. History Trebbiano may have originated in the Eastern Mediterranean, and was known in Italy in Roman times. A subtype was recognized in Bologna in the thirteenth century, and as Ugni blanc made its way to France, possibly during the Papal retreat to Avignon in the fourteenth century. Pedigree An Italian study published in 2008 using DNA typing showed a close genetic relationship between Garganega on the one hand and Trebbiano and several other grape varieties on the other hand. It is therefore possible that Gargan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Welschriesling
Welschriesling is a white wine grape variety, unrelated to the Rhine Riesling, that is grown throughout Central Europe. Origin The descendance of Welschriesling is uncertain. The German name ''Welschriesling'' literally means ' Romanic Riesling' (cf. Walhaz), and most of the synonyms in Central Europe are variations on 'Italian Riesling'. Welschriesling may have been brought to Central Europe by the ancient Romans. However, the Croatian name ''Graševina'' suggests that the origin might be somewhere to the east of the Balkans. A modern theory claims that Welschriesling originated in the Champagne region and came as ''welsch'' (in this case French) Riesling via Heidelberg to the lands of the Austro-Hungarian Monarchy. Wine regions *In Austria, the main regions where it is grown are south and south eastern Styria, in Burgenland, and in the Weinviertel region of Lower Austria, where it is also made into sparkling wine. In Rust near Lake Neusiedl, it is used to make '' Botrytis'' de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sémillon
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. History The Sémillon grape is native to the Bordeaux region. It was known as Sémillon de Saint-Émilion in 1736, while Sémillon also resembles the local pronunciation of the town's name ( emi'ʎuŋ. It first arrived in Australia in the early 19th century and by the 1820s the grape covered over 90% of South Africa's vineyards, where it was known as ''Wyndruif'', meaning "wine grape". It was once considered to be the most planted grape in the world, although this is no longer the case. In the 1950s, Chile's vineyards were made up of over 75% Sémillon. Today, it accounts for just 1% of South African Cape vines. Viticulture Sémillon, which is relatively easy to cultivate, consistently produces six to eight tons of grapes per acre from its vigorous vines.P ...
