Red wine is produced from red, purple or blue grapes. Its color, however, comes not from the juice (since white wine can also be made from red grapes), but from the juice’s contact with red grape skins during the fermentation process.
While their color varies greatly, red wines don’t differ in flavor as much as their white counterparts. But due to the presence of tannins (which also come from the skins), red’s flavors tend to be deeper.
Due to its more complex flavor, red wine is typically served at a warmer temperature than white -- but that doesn’t necessarily mean that room temperature (which is how many of us serve it) is ideal. Try chilling the bottle for 10 to 15 minutes for maximum enjoyment.
