Each year, this crowd-pleasing festival showcases plentiful gourmet food offerings, always-popular wine and beer sampling, nut-inspired cooking demonstrations, live musical entertainment on two outdoor stages, a wonderful art show featuring talented local artists and much more. The event is presented by the Patrick Ranch Museum and sponsored by Tri Counties Bank and Meriam Park - A Development For Food Innovation, C.F. Koehnen & Sons, PG&E, California Olive Ranch, RUSH Personnel Services, Farmers' Circle members and involved media partners.

The California Nut Festival began as a series of events including a blossom tour, spelling bee, book club and chef demonstrations that took place over the course of a two week period, but lacked a single event that brought consumers and local farms together in a meaningful way.
