红葡萄酒
Red wine gains its color and flavor (notably, tannins) from the grape skin, by allowing the grapes to soak in the extracted juice. Red wine is made from dark-colored red grape varieties. The actual color of the wine can range from violet, typical of young wines, through red for mature wines, to brown for older red wines. The juice from most red grapes is actually greenish-white; the red color comes from anthocyanins present in the skin of the grape. A notable exception is the family of rare "teinturier" varieties, which actually have red flesh and produce red juice.
