Wine color
The color of wine is one of the most easily recognizable characteristics of wines. Color is also an element in wine tasting since heavy wines generally have a deeper color. The accessory traditionally used to judge the wine color was the tastevin, a shallow cup allowing one to see the color of the liquid in the dim light of a cellar. The color is an element in the classification of wines.
Color origins
The color of the wine mainly depends on the color of the
Red drupe grapes can produce white wine if they are quickly
The color of a wine can be partly due to
Rosé wine is commonly made by the practice of short maceration (exposing wine to red grape skins for only a short period of time in order to give it a lighter feel closer to that of white wine) or by blending a white wine with a red wine.
Color evolution
The presence of a complex mixture of anthocyanins and procyanidins can increase the stability of color in wine.[2]
As it ages, the wine undergoes chemical autoxidation reactions involving
The exposure of wine to oxygen in limited quantities can be beneficial to the wine. It affects color.[12]
Castavinols are another class of colorless molecules derived from colored anthocyanin pigments.
In model solutions, colorless compounds, such as catechin, can give rise to new types of pigments. The first step is the formation of colorless dimeric compounds consisting of two flavanol units linked by carboxy-
Colors
The main colors of wine are:
- Gray, as in vin gris(gray wine).
- Skin-contact wine, a white wine that has spent some time in contact with its skin, giving it a slightly darker hue.
- Red wine (although this is a general term for dark wines, whose color can be as far from "red" as bluish-violet)
- pinkishin French)
- tawny port.
- White wine (light colored wine)
- Yellow (or straw color), see for instance vin jaune, a special and characteristic type of white wine made in the Jura wine region in eastern France, Jurançon or Sauternes.
