There is a long tradition of winemaking at Casas de Bucalemu and vineyards have grown on their land since the Jesuits arrived in 1631. The vineyards from where these wines come, were only planted in 2008 and their location in the San Domingo region makes them the closest vineyards to the coast in the Leyda Valley at only 9km from the Pacific Ocean. The maritime influence means that Casas de Bucalemu specialises in cool climate grape varieties and their organic vineyards grow on gently rolling hills on soils with high limestone and mineral content, and in which every block is an individual micro-terroir. They vinify in concrete eggs and French oak foudres, which results in elegant, complex wines with unique characteristics.
Production is tiny, at under 3000 bottles of each wine. The Fosiles Pinot Noir is named after the abundance of marine fossils that can be easily found under the top layer of loam in the vineyard soils, while the Salinas Sauvignon refers to the salt flats located close to the vineyard which were, for many years, the only source of salt for Santiago and the surrounding areas.
