Brothers Jérémie and Raphaël Castor are sixth generation vignerons in the tiny village of Cornillon in the southwest of the Côtes du Rhône appellation.

Focused on traditional local grape varieties such as Grenache, Syrah, Mourvèdre, and Cinsault, Chateau St. Nabor produces wines from the area's chalk and clay soils that are fruitful, classically styled, and eminently drinkable.
