Tea growing in Azerbaijan is concentrated in an area of 5.33 thousand square kilometers located within the Lenkeran-Astara region, including the districts of Astara, Lankaran, Masalli, Lerik, Yardimli, and Jalilabad. Around 90% of Azerbaijan's tea is produced in Lankaran close to the southern border with Iran. Tea was first grown around the Caspian Sea region of Azerbaijan in the 1880s. Due to its favorable climatic conditions, the region now produces 99% of the Azerbaijani tea crop.
