Girò
Girò is a red Italian wine grape variety that is grown on Sardinia and is used mostly in the production of fortified wines in the Giro di Cagliari ''Denominazione di origine controllata'' (DOC). The grape was once widely planted throughout Sardinia but its plantings were decimated when the phylloxera epidemic hit the island at the end of the nineteenth century. At the turn of the 21st century there were 552 hectares (1,364 acres) of the grape planted throughout Italy, mostly in the Sardinian provinces of Cagliari and Oristano.J. Robinson, J. Harding and J. Vouillamoz ''Wine Grapes - A complete guide to 1,368 vine varieties, including their origins and flavours'' pg 22-23, 411-412 Allen Lane 2012 Origins Wine historians and ampelographers have speculated that the grape has Spanish origins and may have been introduced to the island when it was ruled by the Crown of Aragon.J.

Giró Blanc
Giró blanc is a pink-skinned Spanish wine grape variety grown in the Balearic islands where it used in white wines produced under the Illes Balears appellation. Ampelographers believe that the grape is indigenous to Majorca with DNA profiling showing no known relationship to the Sardinian wine grape Girò or to Grenache which is known as Girò (without the ''blanc'' designation) on Majorca.J. Robinson, J. Harding and J. Vouillamoz ''Wine Grapes - A complete guide to 1,368 vine varieties, including their origins and flavours'' pg 412 Allen Lane 2012 Today the grape is almost exclusively found on the island of Majorca with in cultivation in 2012. History Ampelographers believe that Giró blanc is likely indigenous to the island of Majorca. The variety was nearly extinct in the late 20th century with only a few scattered vines left on the island. Spanish winegrowers Toni Gelabert and Juaquin Monserrat began cultivating these vines and eventually had 200 vines available for furth ...

Albaranzeuli Nero
Albaranzeuli nero is a red Italian wine grape variety that is primarily found in Sardinia. The grape is often confused with the red Sardinian grape Girò which is believed to be a parent variety of the white grape Albaranzeuli bianco. However recent DNA profiling has not established a direct link between Albaranzeuli nero and either Girò or Albaranzeuli bianco.J. Robinson, J. Harding and J. Vouillamoz ''Wine Grapes - A complete guide to 1,368 vine varieties, including their origins and flavours'' pg 22-23 Allen Lane 2012 History Ampelographers use to believe that the grape was originally Spanish in origin and was introduced to the island when it was ruled by the Crown of Aragon. The hypothesis was bolstered by the grape's Spanish name and its association with Albaranzeuli Bianco which has also been theorized to have had Spanish origins. Viticulture The annual growth cycle of Albaranzeuli nero is characterized by its mid-season budding and its late-season ripening. The vine prod ...

Albaranzeuli Bianco
Albaranzeuli bianco is a white Italian wine grape variety that is grown primarily in Sardinia. Ampelographers use to believe that the grape was originally Spanish in origin and was introduced to the island when it was ruled by the Crown of Aragon. Recent DNA profiling has suggested that the grape may have originated on the island as a crossing between the red Sardinian wine grape Girò and the Spanish table grape Molinera, known locally as ''Pansa Rosa di Málaga'' and distinct from the Veneto wine grape Molinara that is used in Amarone. A pink skinned grape known as Albaranzeuli nero is also found in Sardinia but its exact relationship to Albaranzeuli bianco is not yet clear.J. Robinson, J. Harding and J. Vouillamoz ''Wine Grapes - A complete guide to 1,368 vine varieties, including their origins and flavours'' pg 22-23 Allen Lane 2012 Wine regions According to wine expert Jancis Robinson, Albaranzeuli bianco is "virtually extinct" with only 75 hectares (185 acres) of the grape ...

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.

Straw Wine
Straw wine, or raisin wine, is a wine made from grapes that have been dried to concentrate their juice. The result is similar to that of the ice wine process, but is a much older process and suitable for warm climates. The technique dates back to pre-Classical times with wines becoming fashionable in Roman times and in late Medieval/Renaissance Europe when wines such as Malmsey ('Malvasia' originally from Greece) and Candia (from Crete) were highly sought after. Traditionally, most production of these wines has been in Greece, the islands of Sicily, Cyprus, Northern Italy and the French Alps. However, producers in other areas now use the method as well. Under the classic method, after a careful hand harvest, selected bunches of ripe grapes will be laid out on mats in full sun. (Originally the mats were made of straw, but these days the plastic nets for the olive harvest are likely to be used). This drying will probably be done on well exposed terraces somewhere near the wine pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Desiccate
Desiccation () is the state of extreme dryness, or the process of extreme drying. A desiccant is a hygroscopic (attracts and holds water) substance that induces or sustains such a state in its local vicinity in a moderately sealed container. Industry Desiccation is widely employed in the oil and gas industry. These materials are obtained in a hydrated state, but the water content leads to corrosion or is incompatible with downstream processing. Removal of water is achieved by cryogenic condensation, absorption into glycols, and absorption onto desiccants such as silica gel. Laboratory A desiccator is a heavy glass or plastic container, now somewhat antiquated, used in practical chemistry for drying or keeping small amounts of materials very dry. The material is placed on a shelf, and a drying agent or ''desiccant'', such as dry silica gel or anhydrous sodium hydroxide, is placed below the shelf. Often some sort of humidity indicator is included in the desiccator to show, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Late Harvest Wine
Late harvest wine is wine made from grapes left on the vine longer than usual. ''Late harvest'' is usually an indication of a sweet dessert wine, such as late harvest Riesling. Late harvest grapes are often more similar to raisins, but have been naturally dehydrated while on the vine. Botrytis cinerea, or ''noble rot'', is a mold that causes grapes to lose nearly all of their water content. Wines made from botrytis-affected grapes are generally very sweet. Noble rot Botrytis cinerea is a fungus that affects many wine grapes and causes them to shrivel into moldy raisins. The fungus responds to the humidity and warmth in the climate and attacks the grapes. As the mold penetrates the skin its spores begin to germinate, causing the water inside to evaporate and the grape to dehydrate. With the absence of water, the sugar becomes more concentrated and the botrytis begins to alter the acidity within the grape. Typically botrytis infection begins to take place in late September and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sugars (wine)
Sugars in wine are at the heart of what makes winemaking possible. During the process of fermentation, sugars from wine grapes are broken down and converted by yeast into alcohol (ethanol) and carbon dioxide. Grapes accumulate sugars as they grow on the grapevine through the translocation of sucrose molecules that are produced by photosynthesis from the leaves. During ripening the sucrose molecules are hydrolyzed (separated) by the enzyme invertase into glucose and fructose. By the time of harvest, between 15 and 25% of the grape will be composed of simple sugars. Both glucose and fructose are six-carbon sugars but three-, four-, five- and seven-carbon sugars are also present in the grape. Not all sugars are fermentable, with sugars like the five-carbon arabinose, rhamnose and xylose still being present in the wine after fermentation. Very high sugar content will effectively kill the yeast once a certain (high) alcohol content is reached. For these reasons, no wine is ever fermen ...

Ripeness (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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Acidity (wine)
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 ...

Color Mutations
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 .
