Our vineyards were first certified by California Certifed Organic Farmers (CCOF) in 1986; among the earliest in the state. So for over three decades no synthetic pesticides, herbicides and chemical fertilizers have been used.  We also maintain Calfornia Certified Sustainable Vineyard status. Every day is Earth Day in Yorkville.

Current CCOF Certificate
Our Randle Hill VIneyard was certifed in 1986 and we now have 31 total acres planted.

In 2016 we received this plaque to honor 3 decades of certified organic farming from CCOF and are "Masters of Organics".
