Red or White
The color of wine comes from the skin of the grapes. The juice that comes from nearly every variety of grape when pressed is white or clear. This is true of red grapes as well as white wines. The color or pigments of red grapes are found in the skins of the grapes. In order to make a red wine from red grapes, it is necessary to leave the skins in contact with the juice during fermentation. When the skins are placed in the fermenting 'must', the pigments leech out of the skins and color the wine. When red grapes are pressed and the skins are kept out, the color of the wine remains white and is considered a 'blanc de noirs' (a white wine from red grapes).
