Weldra
Weldra is a white South African wine grape variety that is a crossing of Chenin blanc and Trebbiano. According to wine expert Jancis Robinson Jancis Mary Robinson OBE, ComMA, MW (born 22 April 1950) is a British wine critic, journalist and wine writer. She currently writes a weekly column for the ''Financial Times'', and writes for her website JancisRobinson.com, updated daily. She ..., Weldra can maintain good acidity levels through ripening but tends to produce rather neutral tasting wines.J.

South African Wine
South African wine has a history dating back to 1659 with the first bottle being produced in Cape Town by its founder and gouverner Jan van Riebeeck. Access to international markets led to new investment in the South African wine market. Production is concentrated around Cape Town, with major vineyard and production centres at Constantia, Paarl, Stellenbosch and Worcester. There are about 60 appellations within the Wine of Origin (WO) system, which was implemented in 1973 with a hierarchy of designated production regions, districts and wards. WO wines must only contain grapes from the specific area of origin. "Single vineyard" wines must come from a defined area of less than 6 hectares. An "Estate Wine" can come from adjacent farms if they are farmed together and wine is produced on site. A ward is an area with a distinctive soil type or climate and is roughly equivalent to a European appellation. History The roots of the South African wine industry can be traced to the expl ...

Grape Variety
This list of grape varieties includes cultivated grapes, whether used for wine, or eating as a table grape, fresh or dried (raisin, currant, sultana). For a complete list of all grape species including those unimportant to agriculture, see Vitis. The term ''grape variety'' refers to cultivars rather than actual botanical varieties according to the International Code of Nomenclature for Cultivated Plants, because they are propagated by cuttings and may have unstable reproductive properties. However, the term ''variety'' has become so entrenched in viticulture that any change to using the term ''cultivar'' instead is unlikely. Single species grapes While some of the grapes in this list are hybrids, they are hybridized within a single species. For those grapes hybridized across species, known as interspecific hybrids, see the section on multispecies hybrid grapes below.

Chenel
Chenel is a white South African wine grape variety that was produced by a crossing of Chenin blanc and Trebbiano. The variety was produced in the late 20th century for viticultural purposes and its resistance to various grape rots This is a list of diseases of grapes (''Vitis'' spp.).

Crossing (vine)
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.Wine & Spirits Education Trust ''"Wine and Spirits: Understanding Wine Quality"'' pp. 2-5, Second Revised Edition (2012), London .

Trebbiano
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] |
Jancis Robinson
Jancis Mary Robinson OBE, ComMA, MW (born 22 April 1950) is a British wine critic, journalist and wine writer. She currently writes a weekly column for the ''Financial Times'', and writes for her website JancisRobinson.com, updated daily. She provided advice for the wine cellar of Queen Elizabeth II.

Career Robinson started her wine writing career on 1 December 1975 when she became assistant editor for the trade magazine '' Wine & Spirit''. In 1984, she became the first person outside the wine trade to become a Master of Wine. From 1995 until she resigned in 2010 she served as British Airways' wine consultant, and supervised the BA Concorde cellar luxury selection. As a wine writer, she has become one of ...

Acidity Levels
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 (it is possible to find wines with a high pH for wine and high acidity). 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 o ...

Ripening (wine)
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 ( sparkling, still, fortified, ''rosé'', dessert wine, etc.) 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.J. Cox ''"From Vines to Wines"'' Fourth Edition, pg 97-106 Storey Publishing 1999 There are several factors that contribute to the ripeness of the grape. As the grapes go through ''veraison'', sugars in the grapes will continue to rise as acid levels fall. The balance between sugar (as well as the potential alcohol level) and acids is considered one of the most c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
