Our Story
A family history rooted in Napa’s vineyards
For four generations, the Biale family has worked to preserve the vineyards, varieties, and relationships that helped define Napa Valley. Robert Biale Vineyards was established in 1991 to carry that farming legacy forward. That commitment lives on in every bottle. From old-vine Zinfandel to the growers and historic sites that keep these wines connected to their origins.
“From our beginnings as a winery dedicated to advancing Zinfandel, we have always considered ourselves part farmers, part winemakers, part historic preservation society.”
