The United States is the world’s leading producer of
pistachios accounting for approximately 40% of world
production. Commercial U.S. pistachio production takes
place almost exclusively in the San Joaquin and Sacramento
valley regions of California. Each year, California growers
produced nearly 300,000 tons of pistachios! Pistachios are
also produced in Arizona and New Mexico but to a much
lesser extent
