The California Walnut Board (CWB) represents more than 3,700 California walnut growers and
approximately 70 handlers, grown in multi-generational farmers’ family orchards. California
walnuts, known for their excellent nutritional value and quality, are shipped around the world all
year long, with more than 99% of the walnuts grown in the United States being from California.
The CWB, established in 1948, promotes usage of walnuts in the United States through
publicity and educational programs. The CWB also provides funding for walnut production, food
safety and post-harvest research.
