Today, more than 99% of walnuts grown in the USA come from California where the California Walnut Commission (CWC) represents more than 3,700 California walnut growers, of which many are multi-generational family farms, and approximately 70 handlers. California walnuts deliver excellent quality and nutritional value for consumers worldwide to enjoy year-round. The CWC conducts programs in support of market development to increase the usage and consumption of California walnuts through broad-based marketing activities in addition to supporting scientific nutrition research on the consumption of walnuts.
