Why is red wine, red? Its color can be derived from a vast assortment of grape varietals ranging from grapes that are reddish, deep purple, and even a beautiful blue on the color scale. These grapes give rise to a wine that is color classified with such descriptors as garnet, almost black, dark red, light red, ruby red, opaque purple, deep violet, maroon and the list goes on.
It is the grapeskins that are responsible for the red wine’s distinct color spectrum. The skins are in contact with the grape’s juice during the fermentation process, allowing the dispersion of both color and tannins. The individual wine’s particular red hue depends on the grape type used in the process and the length of time the skin’s pigmentation is in contact with the juice.
