Why is Iranian saffron so expensive?

Iranian saffron has long been deemed one of the most expensive spices in the world, and its high price can be attributed to several factors. Firstly, the cultivation of saffron requires particular weather and soil conditions that are only found in certain regions of Iran. This limited geographic range significantly restricts the overall production capacity, making it difficult to meet the global demand for this luxurious spice. Additionally, the process of harvesting saffron is arduous and labor-intensive, as each flower must be carefully handpicked to obtain the precious saffron threads.
