Pistachios
General Information
The Pistachio nut is indigenous to central Asia. Major exporting countries include Iran, Turkey, Greece, Syria and Italy. Pistachios grow on trees in grape-like clusters and are encased in an outer skin, or hull. When pistachios ripen, the hull turns rosy and the shell within splits naturally, indicating they are ready for harvest. Harvesting usually occurs in September. If the Pistachio nut is not then processed (hulled and dried) within 12 to 24 hours after harvest, the shell will be stained thereby decreasing its commercial value. California processors dye a small percentage of their pistachios not by necessity, but to meet the desires of those consumers who prefer the colorful shells. Pistachio trees produce their nut on an alternative year cycle: large crop one year, light crop the next year.
