Saffron Costs More by Weight Than Gold Because of How It Is Picked

A saffron crocus blooms for about a fortnight in October and November. Each flower opens before sunrise, and by mid-morning the petals are wilting in the field. Inside each is a single style that branches into three deep-red stigmas. Those threads are the spice. The petals, the leaves, the bulb — none of it is saffron. The stigmas are.

A worker walks the rows at dawn, pinches the flowers off at the base, and carries them back to a sorting room. Sitting at a table, a second worker pulls each flower apart and pinches out the three stigmas, which are dried within hours over a low gentle heat. By weight, the stigmas are about a hundredth of the flower. To produce one pound of dried saffron requires roughly 75,000 flowers; one kilogram, around 170,000.

Most of those flowers are picked by hand. Mechanical harvesting has been tried — Spanish and Italian engineers have built saffron-picking robots since the 1990s — but the flower is fragile, the stigma fragile-er, and the harvest window unforgiving. Iran grows about 90 percent of the world's supply, mostly in the Khorasan provinces, where families still hand-pick during a few October weeks. Spain, India, Greece, Morocco, and Afghanistan account for most of the rest.

The economics follow from the labor. Wholesale Iranian saffron in 2024 traded around $2 to $5 per gram; high-grade Spanish coupé reached $10 to $15. Adulteration with safflower, marigold, or shredded paper has been a documented problem since at least the medieval Pepperer's Guild of London. The Saffron Inspection Code of 1444 made adulteration punishable by burning. The price has not stopped tempting fraudsters since.
