In 1928, Italian immigrant Valentin Bianchi bought a vineyard and small winery called El Chiche in Mendoza, Argentina. When Valentin's sons joined the company in the early 1950s, they renamed the company Valentin Bianchi. Today his grandsons, Valentin Eduardo, Ricardo Stradella and Alejandro Ruben manage the estate. The Valentin Bianchi vineyards – Asti, Las Paredes and Dona Elsa – comprise over 716 acres and are located in San Rafael region, an area thought to have the best soil in Mendoza. The vineyards are planted with Italian, Californian and French rootstock. Francisco Martinez is the winemaker for all Valentin 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.
