What are the two main white grape varieties grown in the southern Rhone?

The two main white grape varieties grown in the southern Rhône are Grenache Blanc and Clairette. These varieties are well-suited to the region's climate and soils, which contribute to their successful cultivation. Grenache Blanc tends to produce wines that are fruity, with floral notes and a refreshing acidity, making it a popular choice among producers. Clairette also plays a significant role in blending, offering a balance of freshness and richness that complements the profile of southern Rhône white wines.

While Roussanne and Viognier are prominent white varieties in the northern Rhône and are quite esteemed in certain appellations, they are not the primary focus in the southern Rhône. Similarly, Chardonnay and Sauvignon Blanc are more associated with other regions in France and are not characteristic of the southern Rhône's white wine production. Piquepoul and Trebbiano are lesser-known varieties and not the mainstays in this particular area.
