Berryessa Gap
"Berryessa Gap’s connection to the land runs deep with farming roots from both Spanish and German ancestry in historic Winters, CA in Yolo County. Our father Dan Martinez, Sr., a first generation farmer of Spanish immigrants, planted apricots, almonds, prunes and walnuts in Winters. Dan Sr. partnered with San Francisco winemaker and wine historian Ernest Peninou in 1969 to develop a grapevine rootstock nursery business, Yolo Hills Viticulture Society, supplying UC Davis-sourced grapevine rootstock to what would become renowned Napa and Sonoma Valley vineyards and beyond."
