White 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. Some white wine is also made from grapes with coloured skin, provided that the obtained wort is not stained. Pinot noir, for example, is commonly used to produce champagne. Among the many types of white wine, dry white wine is the most common. More or less aromatic and tangy, it is derived from the complete fermentation of the wort. Sweet wines, on the other hand, are produced by interrupting the fermentation before all the grape sugars are converted into alcohol; this is called Mutage or fortification. The methods of enriching wort with sugar are multiple: on-ripening on the vine, passerillage (straining), or the use of noble rot. Sparkling wines, which are mostly white, are wines where the carbon dioxide from the fermentation is kept dissolved in the wine and becomes gas when the bottle is opened. White wines are often used as an apéritif before a meal, with dessert, or as a refreshing drink between meals. White wines are often considered more refreshing and lighter in both style and taste than the majority of their red wine counterparts. Due to their acidity, aroma and ability to soften meat and deglaze cooking juices, white wines are often used in cooking. History of wine The first trace of wine that has been found dates to 7500 years ago, in present-day Iran but the results of archaeological excavations have not been able to determine from which time wine began to be produced.

Rosé

A rosé (ʁoze) is a type of wine that incorporates some of the color from the grape skins, but not enough to qualify it as a red wine. It may be the oldest known type of wine, as it is the most straightforward to make with the skin contact method. The pink color can range from a pale "onionskin" orange to a vivid near-purple, depending on the grape varieties used and winemaking techniques. Usually, the wine is labelled rosé in French, Portuguese, and English-speaking countries, rosado in Spanish, or rosato in Italian.

Chenin blanc

Chenin blanc (known also as Pineau de la Loire among other names) is a white wine grape variety from the Loire Valley of France. Its high acidity means it can be used to make varieties from sparkling wines to well-balanced dessert wines, although it can produce very bland, neutral wines if the vine's natural vigor is not controlled. Outside the Loire, it is found in most of the New World wine regions; it is the most widely planted variety in South Africa, where it was historically also known as Steen.

German wine

German 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.
