From the 1890s into the mid-1950s, the Cucamonga-Guasti-Ontario Wine District in Southern California was considered California's largest grape-growing and wine-producing district. Much of the valley's grape and wine prosperity is owed to Secundo Guasti (1859-1927), who founded the Italian Vineyard Company in 1883 and built it into a gigantic wine enterprise prior to Prohibition.
In 1998 the Cal Poly Pomona University Library received a donation of early 20th century photographs of the Italian Vineyard Company. The collection was given by local vintner Donald Galleano, owner of the historic Galleano Winery in Mira Loma, California. We have placed this collection of photos here on the web for your enjoyment. Since the original publication of this website, we have acquired additional related materials. We plan to place them on this website as resources allow.
Descriptive information about most of the photographs was taken from an interview conducted with vintner Philo Biane (1909-1999) on August 25, 1998.
