When rosé wine is the primary product, it is produced with the skin contact method. Black-skinned grapes are crushed and the skins are allowed to remain in contact with the juice for a short period, typically one to three days. The must is then pressed, and the skins are discarded rather than left in contact throughout fermentation (as with red wine making). The longer that the skins are left in contact with the juice, the more intense the color of the final wine.
When a winemaker desires to impart more tannin and color to a red wine, some of the pink juice from the must can be removed at an early stage in what is known as the Saignée (from French bleeding) method. The red wine remaining in the vats is intensified as a result of the bleeding, because the volume of juice in the must is reduced, and the must involved in the maceration becomes more concentrated. The pink juice that is removed can be fermented separately to produce rosé.
In other parts of the world, blending, the simple mixing of red wine to a white to impart color, is uncommon. This method is discouraged in most wine growing regions, especially in France, where it is forbidden by law, except for Champagne. Even in Champagne, several high-end producers do not use this method but rather the saignée method.
