Vineyards
                  
                  Originally known as Tre Colline for its memorable undulating terrain, the 36-acre benchland vineyard was renamed in 2003 to honor Beringer’s long-time vineyard manager, Bob Steinhauer, who helped establish the reserve level vineyards across Napa Valley. At 1,800 feet elevation, southwest facing on Howell Mountain, just northeast of Angwin, Steinhauer Ranch features volcanic iron-rich soils notable for their rich red color, with a friable, loose texture. Cabernet Sauvignon and Cabernet Franc thrive in the sparse, infertile soil where cool mountain temperatures with high solar radiation above the fog line allow grapes to languish on the vine, developing bold tannins and distinctive notes.
