The Rhone wine region is situated in the Rhone River Valley in Southern France. It is further divided into two sub-regions, The Northern Rhone and Southern Rhone. The Northern Rhone Valley is known for red wines primarily made from the Syrah grape. French wine law does allow for up to 20% of white wine grapes such as Viognier, Marsanne and Roussanne to be added. Hermitage, Crozes-Hermitage, Cote-Rotie, Cornas and Saint Joseph are the appellations of Northern Rhode red wines.
The Southern Rhone Valley is principally known for its Châteauneuf du Pape. While thirteen grapes, eight red and five white, are allowed by law to be blended when making the wine, Grenache and Mourvedre are the primary grapes used by many estates. Other appellations of note are Côtes du Rhône, Gigondas and Vacqueyras.
Below the Southern Rhone Valley, at the most Southern tip of France is the Languedoc-Roussillon region. In addition to the traditional Rhône grapes of Mourvedre, Grenache, Syrah, and Viognier international varieties such as Merlot, Cabernet Sauvignon, Sauvignon Blanc and Chardonnay are grown here.
