Klevener De Heiligenstein
Klevener de Heiligenstein, also known in English by its German name, Heiligensteiner Klevener, is a designation used on Alsace wine made from pink-skinned Savagnin rose grapes, a variety in the Traminer family, but which is less aromatic than Gewürztraminer, which is widely planted in Alsace. The designation may be allowed for selected vineyards in the villages Bourgheim, Gertwiller, Goxwiller, Heiligenstein and Obernai but, under current appellation rules, the designation may be used until 2021 for specified existing vineyards outside the designation area. Since Savagnin rose is not a permitted variety for other Alsace wines, its replanting outside this area is not allowed. Since most Alsace wines are varietally labeled, it is a common misunderstanding to believe "Klevener de Heiligenstein" to be a local variety. In fact, it is the only geographical designation within the Appellation d'origine contrôlée (AOC) Alsace. History The Savagnin vine was introduced to the Alsace ...

Klevner (other)
Klevner or Clevner is a synonym for various grape varieties and wines, and is primarily used in German-speaking wine regions. The word derives from the Swiss version of the name of the Northern Italian town Chiavenna, Kleven, situated at the north end of Lake Como. Swiss mercenaries brought grapevines from that region back home across the Alps at the beginning of the 16th Century. * In general, it is most commonly applied to various members of the Pinot family, but sometimes to grapes of the Traminer family * In Alsace it usually refers to the variety Pinot blanc, but under the appellation rules it may be applied as a wine designation to a white wine consisting of Auxerrois blanc, Pinot blanc, Pinot gris and Pinot noir (vinified as a white wine, ''blanc de noirs'') in any proportion * In Switzerland, and especially the canton of Zurich, it usually refers to Pinot noir * In Baden, and especially in the district of Ortenau, Clevner usually refers to Traminer * In Slovakia, one parti ...

Cutting (plant)
A plant cutting is a piece of a plant that is used in horticulture for vegetative (asexual) propagation. A piece of the stem or root of the source plant is placed in a suitable medium such as moist soil. If the conditions are suitable, the plant piece will begin to grow as a new plant independent of the parent, a process known as striking. A stem cutting produces new roots, and a root cutting produces new stems. Some plants can be grown from leaf pieces, called leaf cuttings, which produce both stems and roots. The scions used in grafting are also called cuttings. Propagating plants from cuttings is an ancient form of cloning. There are several advantages of cuttings, mainly that the produced offspring are practically clones of their parent plants. If a plant has favorable traits, it can continue to pass down its advantageous genetic information to its offspring. This is especially economically advantageous as it allows commercial growers to clone a certain plant to ensure consis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vintage
Vintage, in winemaking, is the process of picking grapes and creating the finished product—wine (see Harvest (wine)). A vintage wine is one made from grapes that were all, or primarily, grown and harvested in a single specified year. In certain wines, it can denote quality, as in Port wine, where Port houses make and declare vintage Port in their best years. From this tradition, a common, though not strictly correct, usage applies the term to any wine that is perceived to be particularly old or of a particularly high quality. Most countries allow a vintage wine to include a portion of wine that is not from the year denoted on the label. In Chile and South Africa, the requirement is 75% same-year content for vintage-dated wine. In Australia, New Zealand, and the member states of the European Union, the requirement is 85%. In the United States, the requirement is 85%, unless the wine is designated with an AVA, (e.g., Napa Valley), in which case it is 95%. Technically, the 85% r ...

Sweetness Of Wine
The subjective sweetness of a wine is determined by the interaction of several factors, including the amount of sugar in the wine, but also the relative levels of alcohol, acids, and tannins. Sugars and alcohol enhance a wine's sweetness, while acids cause sourness and bitter tannins cause bitterness. These principles are outlined in the 1987 work by Émile Peynaud, ''The Taste of Wine''. History ''Vintage: The Story of Wine'', a book authored by British wine writer Hugh Johnson, presents several methods that have been used throughout history to sweeten wine. The most common way was to harvest the grapes as late as possible. This method was advocated by Virgil and Martial in Roman times. In contrast, the ancient Greeks would harvest the grapes early, to preserve some of their acidity, and then leave them in the sun for a few days to allow them to shrivel and concentrate the sugar. In Crete, a similar effect was achieved by twisting the stalks of the grape to deprive them of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Middle Ages
In the history of Europe, the Middle Ages or medieval period lasted approximately from the late 5th to the late 15th centuries, similar to the post-classical period of global history. It began with the fall of the Western Roman Empire and transitioned into the Renaissance and the Age of Discovery. The Middle Ages is the middle period of the three traditional divisions of Western history: classical antiquity, the medieval period, and the modern period. The medieval period is itself subdivided into the Early, High, and Late Middle Ages. Population decline, counterurbanisation, the collapse of centralized authority, invasions, and mass migrations of tribes, which had begun in late antiquity, continued into the Early Middle Ages. The large-scale movements of the Migration Period, including various Germanic peoples, formed new kingdoms in what remained of the Western Roman Empire. In the 7th century, North Africa and the Middle East—most recently part of the Eastern Ro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Opacity (optics)
Opacity is the measure of impenetrability to electromagnetic radiation, electromagnetic or other kinds of radiation, especially visible light. In radiative transfer, it describes the absorption and scattering of radiation in a transmission medium, medium, such as a plasma (physics), plasma, dielectric, radiation shield, shielding material, glass, etc. An opaque object is neither Transparency (optics), transparent (allowing all light to pass through) nor translucent (allowing some light to pass through). When light strikes an interface between two substances, in general some may be reflected, some absorbed, some scattered, and the rest transmitted (also see refraction). Reflection can be diffuse reflection, diffuse, for example light reflecting off a white wall, or specular reflection, specular, for example light reflecting off a mirror. An opaque substance transmits no light, and therefore reflects, scatters, or absorbs all of it. Both mirrors and carbon black are opaque. Opacity ...

Translucent
In the field of optics, transparency (also called pellucidity or diaphaneity) is the physical property of allowing light to pass through the material without appreciable scattering of light. On a macroscopic scale (one in which the dimensions are much larger than the wavelengths of the photons in question), the photons can be said to follow Snell's law. Translucency (also called translucence or translucidity) allows light to pass through, but does not necessarily (again, on the macroscopic scale) follow Snell's law; the photons can be scattered at either of the two interfaces, or internally, where there is a change in index of refraction. In other words, a translucent material is made up of components with different indices of refraction. A transparent material is made up of components with a uniform index of refraction. Transparent materials appear clear, with the overall appearance of one color, or any combination leading up to a brilliant spectrum of every color. The opposite ...

Veraison
In viticulture, veraison (french: véraison, ) is the onset of the ripening of the grapes. The official definition of ''veraison'' is "change of color of the grape berries". Veraison represents the transition from berry growth to berry ripening, and many changes in berry development occur at veraison. Process Grape berries follow a double sigmoid growth curve. The initial phase of berry growth is a result of cell division and cell expansion. As berry growth of phase I slows this is termed the lag phase. The lag phase is not a physiological growth stage, but an artificial designation between the two growth periods of grape berry development. Post-veraison, fruit acidity decreases due to degradation of malic acid. The degradation of malic acid during ripening makes tartaric acid the predominant acid; grape berries also possess a small amount of citric acid. Tartaric acid accumulates early in phase I of berry growth, while malic acid accumulates at the end of phase I berry grow ...

Genetic Fingerprinting
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.

Morphology (biology)
Morphology is a branch of biology dealing with the study of the form and structure of organisms and their specific structural features. This includes aspects of the outward appearance (shape, structure, colour, pattern, size), i.e. external morphology (or eidonomy), as well as the form and structure of the internal parts like bones and organs, i.e. internal morphology (or anatomy). This is in contrast to physiology, which deals primarily with function. Morphology is a branch of life science dealing with the study of gross structure of an organism or taxon and its component parts. History The etymology of the word "morphology" is from the Ancient Greek (), meaning "form", and (), meaning "word, study, research". While the concept of form in biology, opposed to function, dates back to Aristotle (see Aristotle's biology), the field of morphology was developed by Johann Wolfgang von Goethe (1790) and independently by the German anatomist and physiologist Karl Friedrich Burdach ...

Alsace AOC
Alsace wine or Alsatian wine (french: Vin d'Alsace; german: Elsässer Wein; gsw, label=Haut Rhin Alsatian, d'r Wii vum Elsàss; gsw, label=Bas Rhin Alsatian, de Win vum Elsàss) is produced in the Alsace region in France and is primarily white wine. Because of its Germanic influence, it is the only ''Appellation d'Origine Contrôlée'' region in France to produce mostly varietal wines, typically from similar grape varieties to those used in German wine. Along with Austria and Germany, it produces some of the most noted dry Rieslings in the world as well as highly aromatic Gewürztraminer wines. Wines are produced under three different AOCs: Alsace AOC for white, rosé and red wines, Alsace Grand Cru AOC for white wines from certain classified vineyards and Crémant d'Alsace AOC for sparkling wines. Both dry and sweet white wines are produced. In 2006, vines were grown on 15,298 hectares (37,800 acres) in 119 villages in Alsace, and 111.3 million litres of wine was produced, ...

Appellation
An appellation is a legally defined and protected geographical indication primarily used to identify where the grapes for a wine were grown, although other types of food often have appellations as well. Restrictions other than geographical boundaries, such as what grapes may be grown, maximum grape yields, alcohol level, and other quality factors may also apply before an appellation name may legally appear on a wine bottle label. The rules that govern appellations are dependent on the country in which the wine was produced. History The tradition of wine appellation is very old. The oldest references are to be found in the Bible, where ''wine of Samaria'', ''wine of Carmel'', ''wine of Jezreel'', or ''wine of Helbon'' are mentioned. This tradition of appellation continued throughout the Antiquity and the Middle Ages, though without any officially sanctioned rules. Historically, the world's first exclusive (protected) vineyard zone was introduced in Chianti, Italy in 1716 and th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
