The Rhône valley region is divided between the Northern and Southern Rhône, where the corresponding wines are quite different in style. The Northern Rhône stretches south down the narrow valley of the River Rhône, from the town of Vienne in the north to Valence in the south. Syrah is the main grape, often a little Viogner is blended in with the Syrah which gives the wines a beautiful soft fragrance and texture. Syrah has a distinct peppery character and warmth, red berry fruits and spice are often found on the nose. By contrast, the Southern Rhône covers a much greater area, and is extensively planted with vines. The climate is significantly warmer in the south; Grenache is the main variety to be found here. The most famous region in the south is Châteauneuf-du-Pape.
