Usually found in red wine, tannin is a chemical substance that comes from grape skins, seeds and stems. Tannins are what give wine a dry, bitter taste. Tannins also help prevent oxidation and play a major role in a wine's aging process. A high tannin wine would be a French Bordeaux or any wine produced from grapes such as a Shiraz and Cabernet Sauvignon. Wines such as Pinot Noir and Beaujolais have lighter, thinner skin therefore less tannin. Follow these simple instructions to determine a wine's tannin content.
