Board of Directors

Our 80-member board includes vintners — small, large and in between — representing each of California’s diverse winegrowing regions. The board is supported by the work of numerous committees and working groups. All members are invited to attend our quarterly board meetings and participate in committee meetings, and no winery has more than two votes on our board.
