More and more vintners are converting to organic wine-making in France, especially in the southern growing region of Languedoc-Roussillion.  Due to its drier and warmer climate, it lends itself well to this type of production.  Some vintners like Cazes near Perpignan take it a step further and also use bio-dynamic methods to grow their grapes.  The Languedoc-Roussillion province produces the highest quantity of wine in France, yet is not very well known in the U.S.  Try looking for one of their labels in your wine store or restaurant as they produce some delicious reds, whites and roses, as well as Muscat wine.
