Origin of pistachios

It was popular in the ancient cultures of Babylon, Roman Empire, China, Persia, and Arabia. Also, the nut has been used as a medication in many ancient cultures. Later on, in the 1800s, it was introduced into the Americas.

Commercial production

Iran is the main producer of this nut, followed by the USA, Turkey, China, Syria, Greece, Italy, Afghanistan, Australia, and Tunisia. About sixty percent of the total production is used to prepare ice creams and kulfis, or consumed roasted and salted.

Pistachio production requires warm and dry weather with decent winters. This crop thrives in sandy loam soils with good drainage and mildly alkaline content. Once planted, trees take up to 5 years to begin production, and reach full potential only after 12 years. Currently, there are eleven species of the nut grown commercially.

These nuts are best stored in airtight containers, and can remain fresh for up to three months.
