Sauvignon blanc in the context of "Maceration (wine)"

White wine is a wine that is fermented without undergoing the process of maceration, which involves prolonged contact between the juice with the grape skins, seeds, and pulp. 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 must is not stained. Pinot noir, for example, is commonly used to produce champagne.

Riesling (/ˈriːslɪŋ, ˈriːzlɪŋ/ REE-sling, REEZ-ling, German: [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. As of 2004, Riesling was estimated to be the world's 20th most grown variety at 48,700 hectares (120,000 acres) (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. Riesling is a variety that is highly "terroir-expressive", meaning that the character of Riesling wines is greatly influenced by the wine's place of origin.

In cooler regions, such as the Mosel in Germany, Riesling wines often display apple and tree fruit notes with pronounced acidity that is sometimes balanced by residual sugar. As a late-ripening variety, Riesling can develop citrus and peach notes in warmer areas such as the Palatinate, Alsace, and parts of Austria. In Australia, Riesling is often noted for a characteristic lime note that tends to emerge in examples from the Clare Valley and Eden Valley in South Australia.

French wine is produced throughout all of 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. 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.

Two concepts central to the better French wines are the notion of terroir, which links the style of the wines to the locations where the grapes are grown and the wine is made, and the Protected designation of origin (Appellation d'Origine Protégée, AOP) system, named Appellation d'origine contrôlée (AOC) until 2012. Appellation rules closely define which grape varieties and winemaking practices are approved for classification in each of France's several hundred geographically defined appellations, which can cover regions, villages or vineyards.France is the source of many grape varieties (such as Cabernet Sauvignon, Chardonnay, Pinot noir, Sauvignon blanc, Syrah) that are now planted throughout the world, as well as wine-making practices and styles of wine that have been adopted in other producing countries. Although some producers have benefited in recent years from rising prices and increased demand for prestige wines from Burgundy and Bordeaux, competition from New World wines has contributed to a decline in the domestic and international consumption of French wine to 40 liters per capita.
