Aging of wineThe aging of wine is potentially able to improve the quality of wine. This distinguishes wine from most other consumable goods. While wine is perishable and capable of deteriorating, complex chemical reactions involving a wine's sugars, acids and phenolic compounds (such as tannins) can alter the aroma, color, mouthfeel and taste of the wine in a way that may be more pleasing to the taster. The ability of a wine to age is influenced by many factors including grape variety, vintage, viticultural practices, wine region and winemaking style.
White wineWhite wine is a wine that is fermented without skin contact. The colour can be straw-yellow, yellow-green, or yellow-gold. It is produced by the alcoholic fermentation of the non-coloured pulp of grapes, which may have a skin of any colour. White wine has existed for at least 4,000 years. The wide variety of white wines comes from the large number of varieties, methods of winemaking, and ratios of residual sugar. White wine is mainly from "white" grapes, which are green or yellow in colour, such as the Chardonnay, Sauvignon blanc and Riesling.
French wineFrench wine is produced all throughout France, in quantities between 50 and 60 million hectolitres per year, or 7–8 billion bottles. France is one of the largest wine producers in the world, along with Italian, Spanish, and American wine-producing regions. French wine traces its history to the 6th century BCE, with many of France's regions dating their wine-making history to Roman times. The wines produced range from expensive wines sold internationally to modest wines usually only seen within France such as the Margnat wines of the post war period.
Spanish wineSpanish wine (vinos españoles) includes red, white, and sparkling wines produced throughout the country. Located on the Iberian Peninsula, Spain has over 1.2 million hectares (2.9 million acres) planted in wine grapes, making it the most widely planted wine-producing nation, but the second largest producer of wine in the world, behind Italy and ahead of France and the United States. This is due, in part, to the very low yields and wide spacing of the old vines planted on the dry soils found in some of the Spanish wine regions.
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.
Sparkling wineSparkling wine is a wine with significant levels of carbon dioxide in it, making it fizzy. While the phrase commonly refers to champagne, European Union countries legally reserve that term for products exclusively produced in the Champagne region of France. Sparkling wine is usually either white or rosé, but there are examples of red sparkling wines such as the Italian Brachetto, Bonarda and Lambrusco, and the Australian sparkling Shiraz.
Phenolic content in wineThe phenolic content in wine refers to the phenolic compounds—natural phenol and polyphenols—in wine, which include a large group of several hundred chemical compounds that affect the taste, color and mouthfeel of wine. These compounds include phenolic acids, stilbenoids, flavonols, dihydroflavonols, anthocyanins, flavanol monomers (catechins) and flavanol polymers (proanthocyanidins). This large group of natural phenols can be broadly separated into two categories, flavonoids and non-flavonoids.
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.
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.
Loire Valley (wine)The Loire Valley wine region includes the French wine regions situated along the river Loire from the Muscadet region near the city of Nantes on the Atlantic coast to the region of Sancerre and Pouilly-Fumé just southeast of the city of Orléans in north central France. In between are the regions of Anjou wine, Saumur, Bourgueil, Chinon, and Vouvray. The Loire Valley itself follows the river through the Loire department to the river's origins in the Cévennes but the majority of the wine production takes place in the regions noted above.
WineWine is an alcoholic drink typically made from fermented grapes. Yeast consumes the sugar in the grapes and converts it to ethanol and carbon dioxide, releasing heat in the process. Different varieties of grapes and strains of yeasts are major factors in different styles of wine. These differences result from the complex interactions between the biochemical development of the grape, the reactions involved in fermentation, the grape's growing environment (terroir), and the wine production process.
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.
Ancient Rome and wineAncient Rome played a pivotal role in the history of wine. The earliest influences on the viticulture of the Italian peninsula can be traced to ancient Greeks and the Etruscans. The rise of the Roman Empire saw both technological advances in and burgeoning awareness of winemaking, which spread to all parts of the empire. Rome's influence has had a profound effect on the histories of today's major winemaking regions in France, Germany, Italy, Portugal and Spain.
Ripeness in viticultureIn 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.
Port winePort wine (also known as vinho do Porto, ˌviɲu ðuˈpoɾtu, or simply port) is a Portuguese fortified wine produced in the Douro Valley of northern Portugal. It is typically a sweet red wine, often served with dessert, although it also comes in dry, semi-dry, and white varieties. Other port-style fortified wines are produced outside Portugal - in Argentina, Australia, Canada, France, India, South Africa, Spain, and the United States - but under the European Union Protected Designation of Origin guidelines, only wines from Portugal are allowed to be labelled "port".
Catalan wineCatalan wines are those that are produced in the wine regions of Catalonia. Occasionally, the appellation is applied to some French wine made in the Catalan region of Roussillon and neighboring areas, also known as Northern Catalonia or the Pays catalans. The city of Barcelona is the capital of Catalonia and despite not being in a wine region (although a portion of the Penedès is in the greater comarca of Barcelona), it is the focal point of the Catalan wine industry: a primary consumer market, its port provides export functions and a source of financial resources and investment.
Provence wineProvence (Provençal) wine comes from the French wine-producing region of Provence in southeast France. The Romans called the area provincia nostra ("our province"), giving the region its name. Just south of the Alps, it was the first Roman province outside Italy. Wine has been made in this region for at least 2,600 years, ever since the ancient Greeks founded the city of Marseille in 600 BC. Throughout the region's history, viticulture and winemaking have been influenced by the cultures that have been present in Provence, which include the Ancient Greeks, Romans, Gauls, Catalans and Savoyards.
WinemakingWinemaking (also wine making) or vinification is the production of wine, starting with the selection of the fruit, its fermentation into alcohol, and the bottling of the finished liquid. The history of wine-making stretches over millennia. The science of wine and winemaking is known as oenology. A winemaker may also be called a vintner. The growing of grapes is viticulture and there are many varieties of grapes. Winemaking can be divided into two general categories: still wine production (without carbonation) and sparkling wine production (with carbonation – natural or injected).
