Meet The Team

Bob Herrick 


Bob Herrick graduated from Cal Poly, San Luis Obispo with a degree in Horticultural Science. He has been in the nursery business over 46 years. Bob began a grafted grapevine program to supply vineyards and wineries all over North America. In 1998, he obtained licenses from the French authority for viticulture and enology, ENTAV. This allowed Herrick Grapevines to produce and sell the unique & exclusive varieties and clones from their collection. In late 2019, he moved the St. Helena and Sacramento operations to Red Bluff, CA to remove it from the intense viticulture of the Napa Valley.

He received a degree in Agronomy from the University of Turin and completed a master’s thesis at the French ITV, Institute for the Research on Vineyard and Wine.
