Wikipedia Article About Chenin blanc on Wikipedia Chenin Blanc (or often simply Chenin) is a widely grown wine grape variety, also known as Steen in South Africa, Pineau de la Loire in the Loire region of France. It is used to make white wines in a number of styles with or without some residual sugar. It is the favored grape of the Anjou region of France and, although naturally a hard, acidic grape slow to mature, is made into fine sweet wines that age well for a least ten years in the bottle. In the U.S. the grape all too often ends up in the generic jug wines of bulk producers as acidity enhancer for otherwise flabby high sugar/alcohol blends.
