The unique character of Château du Caillau is rooted in its 10 hectares of south-west facing terraces, where the vines benefit from a sheltered position and the heat-retaining river pebbles that give the "Caillau" its name. The vineyard thrives on a complex soil profile of clay, gravel, and limestone, with vines averaging 25 years of age. To ensure the highest quality, Philippe Bernède employs low-yield harvesting and ecological practices, vinifying each plot in separate tanks to preserve the specific nuances of the terroir. The resulting Malbec is aged for 12 months in a combination of stainless steel and oak, a process that expertly softens the naturally wild character of the region's grapes into a sophisticated, modern red wine.
