The jagged, toothy peaks of the Alpilles form a natural barrier between southern France’s Camargue to the south and the bustling city of Avignon to the north. Tucked at the foot of its rock walls, Domaine de Trévallon is at once the darling of Les Baux de Provence and also its black sheep. There is no person that has done more to elevate the quality and prestige of the wines around Les Baux than Eloi Dürrbach, who began planting vines in the three valleys (where the estate gets its name) in 1973.  Eloi and his father, René, had studied the old texts of the famous 19th-century viticulturalist, Doctor Guyot, who claimed that much of their area of the Bouches-du-Rhône had been planted to Cabernet Sauvignon before the arrival of phylloxera.  Intent on respecting the terroir, they divided their red grape holdings equally among Cabernet Sauvignon and Syrah. Both varietals thrive in the deep chalky soils, and the 50/50 blend turned out to be the perfect balance between the wild qualities of the Mediterranean basin and the structure of a more northerly climate. Eloi blasted the first vineyards out of the mountain himself. Over time and after subsequent planting, the estate is now divided between 15 hectares of reds and 2 hectares of whites.
