History

St. Francis Winery & Vineyards traces its roots to Sonoma Valley, where founder Joe Martin fell in love with the area and established St. Francis Vineyard in 1971, planting 22 acres of Chardonnay and the first 60 acres of Merlot in Sonoma Valley. After achieving success as a grower, Joe opened his own winery in 1979 with business partner Lloyd Canton. The first winemaker, Tom Mackey, joined St. Francis in 1983 and was renowned for elevating the quality and style of Sonoma Merlot as an ultra-premium, stand-alone varietal, while also developing an in-depth understanding of every Sonoma appellation that enabled the acquisition and development of new vineyards and expansion of the wine portfolio. In 1988 St. Francis partnered with the Kopf family, long admired for their historic family legacy in the wine and spirits industry. Today, a new generation of winemakers, Katie Madigan and Chris Louton, continues the winery's tradition.
