The Codorníu family's wine business dates back to the mid-16th century. A document from that period records that the family owned several machines and tools linked to the wine industry. In 1659, Anna Codorníu married Miquel Raventós, uniting two families, each with a long-standing winemaking tradition. Years later, in 1872, Josep Raventós produced Spain's first cava using the "traditional method," founding an entirely new industry in the Alt Penedès region. The Codorníu cellars in Sant Sadurní d'Anoia were built at the commission of Manuel Raventós between the late 19th and early 20th centuries (1895–1915). To design the building, he chose the renowned Catalan architect Josep Puig i Cadafalch. At the time, Codorníu produced around 100,000 bottles of cava a year, and the scale of the new structure seemed too grand. The cellar's location was also unusual for its time, set some distance from the road and the railway line. Manuel Raventós, however, insisted that the family cellar be close to the vineyard, aware that such proximity would be key to improving the quality of the wines. Today, Codorníu continues to oversee the entire production process of all its cavas, from planting the vineyards to the finished product. The winery is equipped with modern installations and equipment.
