In 1928, Italian immigrant Valentín Bianchi bought a vineyard and small winery called El Chiche in Mendoza, Argentina. When Valentín's sons joined the company in the early 1950s, they renamed the company Valentín Bianchi. Today his grandsons, Valentín Eduardo, Ricardo Stradella and Alejandro Ruben manage the estate. The Valentín Bianchi vineyards – Asti, Las Paredes and Dona Elsa – comprise over 716 acres and are located in San Rafael, an area thought to have the best soil in the Mendoza region. The vineyards are planted with Italian, Californian and French rootstock. Francisco Martinez is the winemaker for all Valentín Bianchi labels, and has been with the winery since 1979. In 1996, winemaker Robert Pepi, of Napa, California was hired as a consultant to introduce contemporary techniques while maintaining the wines' traditional Argentine character.
