The appellation of Côtes du Rhône encompasses much of the land of the area, not to mention much of the wine – over two-thirds of the wine produced here is of the Côtes-du-Rhône appellation. Wines here need only be from the Côtes de Rhône geographic area (which is fairly large) and consist of one or more of the 22 varieties permitted. Being such a wide classification, it's a surprise and joy that so many of these wines reach such a high quality. While there are areas in the Northern Rhône that meet the classification of Côtes du Rhône, most all of this appellation is in the Southern Rhône. Wines here are based mostly on Grenache, like other Rhône reds, while the whites focus on Marsanne and Roussanne. Viognier is also allowed although typically used in smaller quantities.
