Red wine is not red because the grapes are red

Red wine has a much deeper taste and has great tannin, which you can read about in tasting wine. Contrary to what many people think red wine is not the color red because the grape is red. While red wines are made from red or black grapes, the fermentation process determines the color of the grape. Many beginners believe the color of the grape will determine the color of the wine. Maceration is the process when you leave the skin in contact with the juice during fermentation.
