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 4000 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 color, such as the Chardonnay, Sauvignon blanc, and Riesling. Some white wine is also made from grapes with colored skin, provided that the obtained wort is not stained. Pinot noir, for example, is commonly used to produce champagne.

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. In addition, due to their acidity, aroma, and ability to soften meat and deglaze cooking juices, white wines are often used in cooking.
