Mas Sainte Berthe (“Mas” means estate in the Provencal dialect) is a family property owned by the David family, located in the picturesque town of Les Baux. The David family’s 40-hectare estate lies at the foot of the mountain, which is a great tourist attraction due to the spectacular ruins of a medieval town on a mountaintop. The estate began as a fruit-growing property in the 1950s and was converted to a vineyard in the early 1960s. The south-facing vineyard lies on unique, rocky, white clay-limestone soil at the foot of Les Baux cliffs, which have a warming effect. The winery maintains a profound respect for its environment. For example, no nitrates are present in their organic fertilizers and natural insect predators are encouraged. The winery was completely renovated 10 years and half the vines are now over 30 years of age, a characteristic that adds further depth and complexity to the wines. Meticulous winemaker Christian Nief, originally from the Nuits St-Georges, is making the finest wines of the region.
