The Rhone wine region in Southern France is situated in the Rhone river valley and produces numerous wines under various Appellation d'origine contrÃ´lÃ©e (AOC) designations. The region's major appellation in production volume is CÃ´tes du RhÃ´ne AOC. The RhÃ´ne is generally divided into two sub-regions with distinct vinicultural traditions, the Northern RhÃ´ne (referred to in French as RhÃ´ne septentrional) and the Southern RhÃ´ne (in French RhÃ´ne mÃ©ridional). The northern sub-region produces red wines from the Syrah grape, sometimes blended with white wine grapes, and white wines from Marsanne, Roussane and Viognier grapes. The southern sub-region produces an array of red, white and rosÃ© wines, often blends of several grapes such as in ChÃ¢teauneuf-du-Pape.
