RieslingRiesling (ˈriːslɪŋ, ˈriːz-; ˈʁiːslɪŋ) is a white grape variety that originated in the Rhine region. Riesling is an aromatic grape variety displaying flowery, almost perfumed, aromas as well as high acidity. It is used to make dry, semi-sweet, sweet, and sparkling white wines. Riesling wines are usually varietally pure and are seldom oaked. , Riesling was estimated to be the world's 20th most grown variety at (with an increasing trend), but in terms of importance for quality wines, it is usually included in the "top three" white wine varieties together with Chardonnay and Sauvignon blanc.
Canopy (grape)In viticulture, the canopy of a grapevine includes the parts of the vine visible aboveground - the trunk, cordon, stems, leaves, flowers, and fruit. The canopy plays a key role in light energy capture via photosynthesis, water use as regulated by transpiration, and microclimate of ripening grapes. Canopy management is an important aspect of viticulture due to its effect on grape yields, quality, vigor, and the prevention of grape diseases. Various viticulture problems, such as uneven grape ripening, sunburn, and frost damage, can be addressed by skillful canopy management.
Yeast in winemakingThe role of yeast in winemaking is the most important element that distinguishes wine from fruit juice. In the absence of oxygen, yeast converts the sugars of the fruit into alcohol and carbon dioxide through the process of fermentation. The more sugars in the grapes, the higher the potential alcohol level of the wine if the yeast are allowed to carry out fermentation to dryness. Sometimes winemakers will stop fermentation early in order to leave some residual sugars and sweetness in the wine such as with dessert wines.
New Zealand wineNew Zealand wine is produced in several of its distinct winegrowing regions. As an island country in the South Pacific Ocean, New Zealand has a largely maritime climate, although its elongated geography produces considerable regional variation from north to south. Like many other New World wines, New Zealand wine is usually produced and labelled as single varietal wines, or if blended, winemakers list the varietal components on the label.
VeraisonIn viticulture, veraison (véraison, veʁɛzɔ̃) 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. 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.
Austrian wineAustrian wines are mostly dry white wines (often made from the Grüner Veltliner grape), though some sweeter white wines (such as dessert wines made around the Neusiedler See) are also produced. About 30% of the wines are red, made from Blaufränkisch (also known as Lemberger, or as Kékfrankos in neighbouring Hungary), Pinot noir and locally bred varieties such as Zweigelt. Four thousand years of winemaking history counted for little after the "antifreeze scandal" of 1985, when it was revealed that some wine brokers had been adulterating their wines with diethylene glycol.
Pinot noirPinot noir (pino nwaʁ) is a red-wine grape variety of the species Vitis vinifera. The name may also refer to wines created predominantly from pinot noir grapes. The name is derived from the French words for pine and black. The word pine alludes to the grape variety having tightly clustered, pinecone–shaped bunches of fruit. Pinot noir is grown around the world, mostly in cooler climates, and the variety is chiefly associated with the Burgundy region of France.
Muscat (grape)The Muscat family of grapes includes over 200 grape varieties belonging to the Vitis vinifera species that have been used in wine production and as raisin and table grapes around the globe for many centuries. Their colors range from white (such as Muscat Ottonel), to yellow (Moscato Giallo), to pink (Moscato rosa del Trentino) to near black (Muscat Hamburg). Muscat grapes and wines almost always have a pronounced floral aroma.
German wineGerman wine is primarily produced in the west of Germany, along the river Rhine and its tributaries, with the oldest plantations going back to the Roman era. Approximately 60 percent of German wine is produced in the state of Rhineland-Palatinate, where 6 of the 13 regions (Anbaugebiete) for quality wine are situated. Germany has about 103,000 hectares (252,000 acres or 1,030 square kilometers) of vineyard, which is around one tenth of the vineyard surface in Spain, France or Italy.
Aroma of wineThe aromas of wine are more diverse than its flavours. The human tongue is limited to the primary tastes perceived by taste receptors on the tongue – sourness, bitterness, saltiness, sweetness and savouriness. The wide array of fruit, earthy, leathery, floral, herbal, mineral, and woodsy flavour present in wine are derived from aroma notes sensed by the olfactory bulb. In wine tasting, wine is sometimes smelled before taking a sip in order to identify some components of the wine that may be present.
