Core tip: From September to November each year, the pistachio orchards in California's Central Valley in the United States enter their peak harvest season. According to industry data estimates from the U.S. Pistachio Growers Association, the U.S. pistachio production for the 2025 season is expected to reach between 680,000 and 770,000 tons, a significant increase of up to 12% compared to the average production of 590,000 tons in the 2023 and 2024 seasons. California pistachios, thanks to their drought-resistant characteristics and high economic value, have seen a continuous expansion in planting area over the past decade, making them the region's sixth largest agricultural product, with a value surpassing that of traditional crops such as strawberries and tomatoes.
