Robert Biale Vineyards in Napa has its roots in the 1930s, when the Biale family started growing Zinfandel grapes and other produce on the outskirts of Napa. The family grapes mostly were sold to local wineries, though the Biales saved some to make wine for the family. The winery was formally founded in 1991 when Aldo Biale and his son Robert formed a partnership with winemaker Al Perry and wine salesman Dave Pramuk to produce and market Zinfandel. Today the estate grows Zinfandel and Petite Sirah on 25 acres in Napa Valley.
