A large pistachio processing factory in California is producing millions of shelled pistachios, which are exported worldwide, with a significant portion going to China. The demand for pistachios in America is also on the rise, making the state the world's largest exporter of pistachios, surpassing Iran. California's pistachio crop, worth nearly $3 billion, is the state's sixth-largest agricultural product and is expected to expand further due to the crop's drought and cold tolerance, requiring less water than almonds and walnuts. The company Wonderful, the largest pistachio industry brand, plans to increase pistachio cultivation, contributing to the shift towards more profitable perennial crops in California.
