Kalleh Ghouchi pistachio is one of the well-known and popular Iranian pistachio varieties. Due to its large size and sweet, pleasant flavor, it has many fans in both domestic and international markets, especially in Arab countries.

Kalleh Ghouchi pistachio has a sweeter taste compared to other varieties, and its size grading typically ranges from 18–20 to 24–26, reflecting the remarkable largeness of this pistachio type. Its appearance closely resembles American pistachios, which has caused it, despite its excellent qualities, to somewhat yield its position to Akbari pistachios in the global market.

Nevertheless, Kalleh Ghouchi kernels remain highly popular internationally and, because of their color, flavor, and distinctive size, are especially valued in the food and confectionery industries.

From an agricultural perspective, Kalleh Ghouchi pistachio trees are notable for early flowering and late fruit ripening. These traits provide important advantages in harvest timing management and relative resistance to certain climatic conditions.
