Terroir

• Granitic soils predominate across the territory, accompanied by metamorphic rocks (leptynites, anatexites, gneiss) rich in quartz and mica, promoting heat retention.
• The Mistral, a violent, cold, and dry wind from the north, is channelled through the Rhône valley by the Massif Central to the west and the Alps to the east.
• The climate is semi-continental in type, with alternating Mediterranean, continental, and oceanic influences; winters can be harsh, with frost and occasional snow.
• The territory extends across cantons in the southern Loire, the Rhône, the Rhodanian Isère, the northern Drôme, and the northern Ardèche, following the course of the Rhône flanked by hills.
