La Raia is a biodynamic estate in the Gavi hills of Piemonte, Italy, founded in 2003 by the Rossi Cairo family. Spanning 180 hectares, including 50 hectares of vineyards, the estate is Demeter-certified and adheres to biodynamic principles, emphasizing soil vitality, biodiversity, and minimal intervention. The estate's commitment to sustainability extends to the winery's architecture, which features a pisé (rammed earth) structure designed by Austrian architect Martin Rauch. This construction method harmonizes with the surrounding landscape and reflects the estate's dedication to environmental stewardship.
