Wine made from white (light) grape varieties, whereby the colour of the berries can vary greatly from white, to yellow, green, brownish to red. White wines are produced in much larger quantities (compared to red wine), especially in cooler wine-growing regions. The production differs significantly from the more elaborate red wine production. In contrast to red wine, pressing takes place immediately after the grapes have been destemmed and crushed. Most of the must is fermented without stems and berry skins (see destemming); exceptions are the Natural Wines. A special white wine is made from dark, i.e. red wine grapes; this technique is called blanc de noirs (white from black) or white pressing.
