Girò Di Cagliari
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.

Italian Wine
Italian wine is produced in every region of Italy. Italy is the world's largest producer of wine, with an area of under vineyard cultivation, and contributing a 2013–2017 annual average of 48.3 million hl of wine. In 2018 Italy accounted for 19 per cent of global production, ahead of France (17 per cent) and Spain (15 per cent). Italian wine is both exported around the world and popular domestically among Italians, who consume an average of 42 litres per capita, ranking fifth in world wine consumption. The origins of vine-growing and winemaking in Italy has been illuminated by recent research, stretching back even before the Phoenician, Etruscans and Greek settlers, who produced wine in Italy before the Romans planted their own vineyards. The Romans greatly increased Italy's viticultural area using efficient viticultural and winemaking methods. History Vines have been cultivated from the wild ''Vitis vinifera'' grape for millennia in Italy. It was previously believed that ...

DNA Profiling
DNA profiling (also called DNA fingerprinting) is the process of determining an individual's DNA characteristics. DNA analysis intended to identify a species, rather than an individual, is called DNA barcoding. DNA profiling is a forensic technique in criminal investigations, comparing criminal suspects' profiles to DNA evidence so as to assess the likelihood of their involvement in the crime. It is also used in paternity testing, to establish immigration eligibility, and in genealogical and medical research. DNA profiling has also been used in the study of animal and plant populations in the fields of zoology, botany, and agriculture. Background Starting in the 1980s, scientific advances allowed the use of DNA as a material for the identification of an individual. The first patent covering the direct use of DNA variation for forensicsUS5593832A was filed by Jeffrey Glassberg in 1983, based upon work he had done while at Rockefeller University in the United States in 1981. ...

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 . In commercial viticulture, grapevines are r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pierre Galet
Pierre Galet (28 January 1921 – 30 December 2019) was a French ampelographer and author who was an influential figure within ampelography in the 20th century and before DNA typing was widely introduced. Beginning in the 1950s, Pierre Galet introduced a system for identifying varieties based on the shape, contours and characteristics of the leaves of the vines, petioles, growing shoots, shoot tips, grape clusters, as well as the colour, size, seed content and flavour of the grapes. The impact and comprehensiveness of his work earned him the consideration as the "father of modern ampelography". J. Robinson (ed) ''"The Oxford Companion to Wine"'' Third Edition pg 295 Oxford University Press 2006 He started publishing within ampelography in the 1950s and his Ph.D. thesis was presented in 1967. He has also written popular science books on grape varieties. Galet was active at the École Nationale Supérieure Agronomique de Montpellier. Biography Pierre Galet was born in Monaco in ...

Balearic Islands
The Balearic Islands ( es, Islas Baleares ; or ca, Illes Balears ) are an archipelago in the Balearic Sea, near the eastern coast of the Iberian Peninsula. The archipelago is an autonomous community and a province of Spain; its capital is Palma. The 2007 Statute of Autonomy designates the Balearic Islands as one of the ''nationalities'' of Spain. The official languages of the Balearic Islands are Catalan and Spanish. Its four largest islands are Mallorca, Menorca, Ibiza, and Formentera. Many of its minor islands and islets are close to the larger islands, including Cabrera, Dragonera, and S'Espalmador. The islands have a Mediterranean climate, and the four major islands are all popular tourist destinations. Ibiza, in particular, is known as an international party destination, attracting many of the world's most popular DJs to its nightclubs. The islands' culture and cuisine are similar to those of the rest of Spain but have their own distinctive features. Etymology ...
