Although Ridge Vineyards was founded in the early 1960s, wine production at the winery's Monte Bello location has a much longer history. Grapevines were first planted on Monte Bello Ridge by Osea Perrone, a doctor and prominent member of the northern California Italian immigrant community, in 1885. The first Monte Bello wine was produced in 1892. Following Prohibition, the vineyard at Monte Bello passed through the hands of several amateur winemakers until it was purchased in 1959 by David Bennion, Charles Rosen, Hewitt Crane, and Howard Zeidler, all engineers at nearby Stanford Research Institute. Ridge Vineyards was bonded and produced its first commercial wine, a Monte Bello Cabernet Sauvignon, in 1962.
