Very diverse wines take most advantage of the weather and winemaking conditions of the Rhône valley. The climate in Côtes du Rhône is hot and sunny, more constant than in the other French wine producing regions. The soil is stony, mainly made of granite.
Grenache is the dominant variety in most Southern Rhône wines, especially in Châteauneuf-du-Pape where it is typically over 80% of the blend. In Australia it is typically blended in "GSM" blends with Syrah and Mourvèdre.
