When Stefano Riboli’s uncle, Santo Cambianica, founded San Antonio Winery in 1917, he began a winemaking tradition that has spanned four generations. Today, the entire Riboli family continues this proud devotion to quality and heritage. To celebrate this achievement, all of our handcrafted products belong to the Riboli Family of Wines. Our commitment is reflected in every bottle that bears the Riboli name.
Our family’s dedication extends beyond the art of making fine wine to the science of growing exceptional grapes. We farm vineyards in select coastal regions of California renowned for producing exquisite wines. Our vineyard ranches are located in some of the most prestigious regions in California alongside numerous world-renown wineries and vineyards. 
The first vineyard acquisition occurred during the 1970’s in Monterey County. The vineyards are spread throughout the Santa Lucia Highlands, Arroyo Seco, and Soledad appellations. Today neighbors include Pisoni Vineyards and Winery, Hahn Estates, Talbott Vineyards, and Paraiso Vineyards. The Riboli Family then purchased vineyard property in the prestigious Rutherford appelation of Napa Valley in 1986, which placed the Riboli’s in excellent company along the Silverado Trail with wineries such as Beaulieu Vineyard, Caymus Vineyards, and ZD Wines. A few years ago the Riboli Family set its sites on the Paso Robles AVA of San Luis Obispo County. Paso Robles is known for its intensely hot days and drastic temperature drop in the evening which produces vibrant color, rich fruit, and complex structure in the grapes. There the family centered on the Templeton Gap area which is a unique location Paso Robles. Cool, marine air funnels through the Coastal Range and allows for daily temperatures well below the rest of the region. The vineyards are close to Eberle Vineyards and Wildhorse.
