How is the color of Rosé wine determined?

The color of rosé wine is determined by a number of factors such as the variety of the grape and the length of time that the grape skins were in contact during fermentation. Red grape varieties are responsible for the pink color of rose, while the length of time that the grape skins are in contact with the juice determines the depth of the color. Short maceration time provide lighter pink colors, whereas extended contact produces darker, more vivid tones.
