Red wine gets its color from the skin of the grape. Many grape varietals make up red wine. Each variety gives a different shade of red. An individual wine’s color depends on what type of grape was used to make it and how long the skin was left in the juice before being extracted.
They are usually judged by their body. A light-bodied wine should not overpower the taste buds. It pairs well with food that is rich in flavor. The French red wine Beaujolais Nouveau, is a good example of this kind of wine. A medium-bodied red wine is a slightly heavier wine for example, a Shiraz or Merlot. Full-bodied wines are denser and have higher alcohol content.
