The Alpilles mountain chain forms a 30 km long natural limestone rock barrier (mesozoic marine deposits) offering a both picturesque and complex relief.
Directly below the commune of Les Baux, these rocks blend together with a site rich in somewhat deep bauxite. The percentage of gravel produced from the disintegration of rock has a marked influence on the structure of soils and offers up ideal conditions for vine plantation. This mixture of clay, gravel and marl favours the natural drainage of the land.
The barrier formed by the mountains regulates the microclimate.
The north-westerly mistral wind, a frequent visitor here, is key to the drying and hence the health status of the vineyard.
The fortuitous concurrence of a history, geology and climate.
