The Northern Rhône. Syrah is the only red grape variety permitted in red AOC wines from this sub-region. The grape, which is believed to have originated in or close to the Rhône region, is also widely known as Shiraz, its name in Australia and much of the English-speaking world, and has recently become very popular with consumers around the world. For wines bearing the Cornas AOC designation, Syrah must be used exclusively, whereas other reds from the northern Rhône sub-region may be blended with white wine grapes, either Viognier or Marsanne and Roussanne, depending on the appellation. However, while this is allowed by the AOC rules, blending with white grapes is only widely practiced for Côte-Rôtie. Viognier by itself is used for white wines from Condrieu and Château-Grillet. Marsanne and Roussanne are in turn used for the whites from Crozes-Hermitage, Hermitage, Saint Joseph, and Saint Péray.
