Maceration (wine) in the context of "Pressing (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.

A rosé (French: [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; rosat in Catalan; or rosato in Italian.

There are three major ways to produce rosé wine: skin contact, saignée, and blending. Rosé wines can be made still, semi-sparkling or sparkling and with a wide range of sweetness levels from highly dry Provençal rosé to sweet White Zinfandels and blushes. Rosé wines are made from a wide variety of grapes and can be found all around the globe.

Maceration is the process of preparing foods by softening, breaking down into pieces, or extracting its flavors, typically using a liquid.

Maceration is an important step in the making of wine, and is also used in the production of other flavored alcoholic beverages, such as cordials, liqueurs, and Geister.

Secondary fermentation is a process commonly associated with winemaking, which entails a second period of fermentation in a different vessel than the one used to start the fermentation process. An example of this would be starting fermentation in a carboy or stainless steel tank and then moving it over to oak barrels. Rather than being a separate, second fermentation, this is most often one single fermentation period that is conducted in multiple vessels. However, the term does also apply to procedures that could be described as a second and distinct fermentation period.
