Mortágua (grape)
Touriga Nacional is a variety of red wine grape, considered by many to be Portugal's finest. Despite the low yields from its small grapes, it plays a big part in the blends used for ports, and is increasingly being used for table wine in the Douro and Dão. Touriga Nacional provides structure and body to wine, with high tannins and concentrated flavors of black fruit. Jancis Robinson has compared its relationship with Touriga Francesa to the partnership between Cabernet Sauvignon and Cabernet Franc, the former providing structure, the latter filling out the bouquet.J. Robinson ''Vines, Grapes & Wines'' pg 216 Mitchell Beazley 1986 Viticulture The vine is very vigorous, and good results depend on keeping it in check. In the Douro it is grown in searing heat in steep schisty vineyards that are more rock than soil. The alternative name of Mortágua pays tribute to these harsh conditions. It is usually trained under one of the Guyot systems, and needs severe pruning to keep it ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vitis Vinifera
''Vitis vinifera'', the common grape vine, is a species of flowering plant, native to the Mediterranean Basin, Mediterranean region, Central Europe, and southwestern Asia, from Morocco and Portugal north to southern Germany and east to northern Iran. , there were between List of grape varieties, 5,000 and 10,000 varieties of ''Vitis vinifera'' grapes though only a few are of commercial significance for wine and table grape production. The wild grape is often classified as ''Vitis vinifera'' ''sylvestris'' (in some classifications considered ''Vitis sylvestris''), with ''Vitis vinifera'' ''vinifera'' restricted to cultivated forms. Domesticated vines have hermaphrodite#Plants, hermaphrodite flowers, but ''sylvestris'' is plant sexuality, dioecious (male and female flowers on separate plants) and pollination is required for fruit to develop. Grapes can be eaten fresh or dried to produce raisins, Sultana (grape)#Raisins, sultanas, and Zante currant, currants. Grape leaves are used ...

Cabernet Sauvignon
Cabernet Sauvignon () is one of the world's most widely recognized red wine grape varieties. It is grown in nearly every major wine producing country among a diverse spectrum of climates from Australia and British Columbia, Canada to Lebanon's Beqaa Valley. This grape variety appeared in France in the 17th century as a result of natural crossbreeding. Its popularity is often attributed to its ease of cultivation—the grapes have thick skins and the vines are hardy and naturally low yielding, budding late to avoid frost and resistant to viticulture hazards. The classic profile of Cabernet Sauvignon tends to be full-bodied wines with high tannins and noticeable acidity that contributes to the wine's aging potential. In cool areas, it has flavors of blackcurrant and green pepper; in warmer places, it may taste like black cherry and olive; in very hot climates, it can have a jammy flavor. History and origins For many years, the origin of Cabernet Sauvignon was not cl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Portuguese Grape Varieties
Portugal's history of viticulture and vinification covers many centuries and has included the use of an extensive number native varieties. In addition, through experimentation and field trials a number of new varieties have emerged and are now playing key roles in producing the country's wide array of wines. The relative absence of many international varieties such as Cabernet Sauvignon, Chardonnay and Semillon is another characteristic of this country's wine industry, although in recent decades many of these varieties have been brought into wider use as the lists below reveal. Portugal's wine production in 2019 was 6.5 million hectolitres (Mhl), consistent with its annual average since 2015, and the forecast for 2020 is also 6.5 Mhl. This industry makes an important contribution to the country's annual income by attracting a vigorous local market and by being exported all over the world with France, the United States, the United Kingdom, Brazil and Germany as the main destinati ...

List Of Port Wine Grapes
According to the Method of Punctuation of the Plots of Land of Vineyards of the Region of Douro (decree nº 413/2001), there were 30 recommended and 82 permitted grape varieties in Port wine production. The quality and characteristics of each grape varies with the classification of grape varieties making a distinction between "Very Good", "Good", "Average", "Mediocre" and "Bad" quality grapes. But this classification is actually in revaluation based on the technical and scientific data of the CEVD (Center of Wine Studies of Douro). The six most widely used grapes for red Port wine are Touriga Franca, Tinta Roriz, Tinta Barroca, Touriga Nacional, Tinta Cão and Tinta Amarela. T. Stevenson ''"The Sotheby's Wine Encyclopedia"'' pg 335 Dorling Kindersley 2005 Black grapes Recommended Grape Varieties Very good * Bastardo * Donzelinho tinto * Marufo * Tinta Francisca * Tinta Roriz * Tinta Cão * Touriga Franca * Touriga Nacional Good * Castelão * Cornifesto * Malvasia Preta * ...

Tannins In Grape
Procyanidins are members of the proanthocyanidin (or condensed tannins) class of flavonoids. They are oligomeric compounds, formed from catechin and epicatechin molecules. They yield cyanidin when depolymerized under oxidative conditions. See the box below entitled "Types of procyanidins" for links to articles on the various types. Distribution in plants Procyanidins, including the lesser bioactive / bioavailable polymers (4 or more catechines), represent a group of condensed flavan-3-ols that can be found in many plants, most notably apples, maritime pine bark, cinnamon, aronia fruit, cocoa beans, grape seed, grape skin, and red wines of ''Vitis vinifera'' (the common grape). However, bilberry, cranberry, black currant, green tea, black tea, and other plants also contain these flavonoids.USDA, August 2004USDA Database for the Proanthocyanidin Content of Selected Foods PDF summary accessed from main USDA pag Page accessed July 31, 2015 Procyanidins can also be isolat ...

Extract (wine)
An extract (essence) is a substance made by extracting a part of a raw material, often by using a solvent such as ethanol, oil or water. Extracts may be sold as tinctures or absolutes or dried and powdered. The aromatic principles of many spices, nuts, herbs, fruits, etc., and some flowers, are marketed as extracts, among the best known of true extracts being almond, cinnamon, cloves, ginger, lemon, nutmeg, orange, peppermint, pistachio, rose, spearmint, vanilla, violet, rum, and wintergreen. Extraction techniques Most natural essences are obtained by extracting the essential oil from the feedstock, such as blossoms, fruit, and roots, or from intact plants through multiple techniques and methods: * Expression (juicing, pressing) involves physical extraction material from feedstock, used when the oil is plentiful and easily obtained from materials such as citrus peels, olives, and grapes. * Absorption (steeping, decoction). Extraction is done by soaking material in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dao Red Wine
The Tao or Dao is the natural way of the universe, primarily as conceived in East Asian philosophy and East Asian religions, religion. This seeing of life cannot be grasped as a concept. Rather, it is seen through actual living experience of one's everyday being. The concept is represented by the Chinese character , which has meanings including 'way', 'path', 'road', and sometimes 'doctrine' or 'principle'. In the ''Tao Te Ching'', the ancient philosopher Laozi explains that the Tao is not a name for a thing, but the underlying natural order of the universe whose ultimate essence is difficult to circumscribe because it is non-conceptual yet evident in one's being of aliveness. The Tao is "eternally nameless" and should be distinguished from the countless named things that are considered to be its manifestations, the reality of life before its descriptions of it. Description and uses of the concept The word "Tao" has a variety of meanings in both the ancient and modern Chin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pollinate
Pollination is the transfer of pollen from an anther of a plant to the stigma of a plant, later enabling fertilisation and the production of seeds. Pollinating agents can be animals such as insects, for example bees, beetles or butterflies; birds, and bats; water; wind; and even plants themselves. Pollinating animals travel from plant to plant carrying pollen on their bodies in a vital interaction that allows the transfer of genetic material critical to the reproductive system of most flowering plants. Self-pollination occurs within a closed flower. Pollination often occurs within a species. When pollination occurs between species, it can produce hybrid offspring in nature and in plant breeding work. In angiosperms, after the pollen grain (gametophyte) has landed on the stigma, it germinates and develops a pollen tube which grows down the style until it reaches an ovary. Its two gametes travel down the tube to where the gametophyte(s) containing the female gametes are held with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Clone (plant)
Cloning is the process of producing individual organisms with identical genomes, either by natural or artificial means. In nature, some organisms produce clones through asexual reproduction; this reproduction of an organism by itself without a mate is known as parthenogenesis. In the field of biotechnology, cloning is the process of creating cloned organisms of cells and of DNA fragments. The artificial cloning of organisms, sometimes known as reproductive cloning, is often accomplished via somatic-cell nuclear transfer (SCNT), a cloning method in which a viable embryo is created from a somatic cell and an egg cell. In 1996, Dolly the sheep achieved notoriety for being the first mammal cloned from a somatic cell. Another example of artificial cloning is molecular cloning, a technique in molecular biology in which a single living cell is used to clone a large population of cells that contain identical DNA molecules. In bioethics, there are a variety of ethical positions reg ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Yield (wine)
In viticulture, the yield is a measure of the amount of grapes or wine that is produced per unit surface of vineyard, and is therefore a type of crop yield. Two different types of yield measures are commonly used, mass of grapes per vineyard surface, or volume of wine per vineyard surface. The yield is often seen as a quality factor, with lower yields associated with wines with more concentrated flavours, and the maximum allowed yield is therefore regulated for many wine appellations. Units and conversions In most of Europe, yield is measured in hectoliters per hectare, i.e., by the volume of wine. In most of the New World, yield is measured in tonnes per hectare (or short tons per acre in the USA) – i.e. by mass of grapes produced per unit area. Due to differing winemaking procedures for different styles of wine, and different properties of different grape varieties, the amount of wine produced from a unit mass of grapes varies. It is therefore not possible to make an exac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Guyot Systems
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.J. Robinson (ed) ''"The Oxford Companion to Wine"'' Third Edition pg 134-230, 300-341, 399-413, 551-553, 617-634, 661-692, 706-733 Oxford University Press 2006 In deciding on what type of vine training system to use, growers also consider the climate conditions of the vineyard where the amount of sunlight, humidity and wind could have a large impact on the exact benefits the training system offers. For instance, while having a large spread out canopy (such as what the ' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
