The California Walnut Commission (CWC) was established in 1987 to represent the interests of the California walnut industry, which includes over 4,500 growers and nearly 100 handlers. The CWC is primarily involved in health research and export market development, aiming to enhance the global demand and awareness of California walnuts. The commission also engages in various marketing and promotional activities, including publicizing health benefits and supporting scientific research related to walnut consumption.
