Why Is Saffron So Expensive? Flowers, Hours and Hectares

One kilogram of dried saffron takes the stigmas of roughly 140,000 to 145,000 flowers and over 400 hours of hand labor, according to a 2020 good-practice guide from Kashmir’s agricultural university.¹ That’s the heart of the price: almost all the work is done by hand. Add a two-week flowering window, low yields per hectare, a plant that can’t be grown from seed, and a supply concentrated in one country, and you have what Encyclopaedia Britannica still calls the most expensive spice in the world.²

The short answer

It is all picked and cleaned by hand

Saffron is the dried stigma of the Crocus sativus flower, three to a bloom. Someone has to separate the stigmas from each flower before drying. Katzer describes the whole process, right through final drying, as work done by families with little or no modern technology.³ The Kashmir guide’s figure is the most specific we found: over 400 hours of hand labor for 1.0 kg of dry saffron.¹ That’s about 180 hours per pound. A widely repeated figure of 80 hours per pound is less than half that, and we couldn’t find a source for it.

You’ll often hear that the stigmas are too delicate for any machine to remove. That may be true in practice, but none of the sources we opened says so.

It takes a great many flowers

How many flowers go into saffron is its most repeated statistic, and the sources don’t agree:

These are different estimates from different places, so we haven’t averaged them. Put into the same unit, all but the last land between about 100,000 and 170,000 flowers per kilogram (Britannica’s figure works out to about 165,000 per kg). None of the sources explains what’s behind the spread. Our saffron page has more on these figures.

Drying removes most of the weight

The Kashmir guide says 1 kg of dried saffron takes 4 kg of fresh.¹ So roughly three-quarters of the harvested weight goes off as water. The 80% figure you’ll see around is close, but it’s not what this source gives.

The harvest is short and early

Katzer says the flowers appear for about two weeks at the end of October or the start of November.³ The Kashmir guide says harvesting has to start shortly after dawn and finish quickly, and recommends picking in the early morning.¹

Yields per hectare are tiny

The cumin row is a national average for comparison, not a per-farm figure. In US units, 5 to 10 kg/ha is roughly 4.5 to 9 pounds per acre. A claim that saffron yields “about a pound per acre” against cumin’s “300 pounds per acre” gets passed around a lot. Neither number matches these sources. On the figures above, cumin out-yields saffron by roughly 75 to 150 times by weight, by our math.

It cannot be grown from seed

Cultivated saffron is a sterile triploid, and growing it from daughter corms is considered the only way to reproduce it.⁶ Katzer says the same: it can be propagated only from corms.³

Supply is concentrated, and weather matters

Iran dominates production. The Kashmir guide gives Iran about 88.8% of world output, and a 2022 peer-reviewed paper puts it around 90%. Neither figure is tied to a specific crop year.¹⁴ AHPA lists India, Greece, Afghanistan, Morocco, Spain, Italy and China as smaller producers.⁵ Katzer’s page paints a different picture, with Spain and Iran together at more than 80% of about 300 tonnes a year, but it doesn’t give a date.³

Weather affects the crop. The Kashmir guide says rain or irrigation in August and September helps boost early flowering and production.¹ You’ll often read that drought and climate change will keep prices high, or that Spain’s saffron industry shrank because of labor costs. None of the sources we opened supports either claim.

What saffron actually costs

Saffron prices swing wildly by grade, origin and where you buy it. Each figure below has a different scope, so you can’t compare them directly.

The same 2020 report says Iranian export prices fell from USD 4,000 to 5,000 per kg in 2009 to 2011 to around USD 400 to 500, while retail prices stayed high.⁹ Katzer also says saffron sells for about one-tenth as much in producing countries, though at lower quality.³ The newsletter describes brokers reselling saffron at USD 7,000 per kg or more on the global market. And Katzer notes that cheaper grades can include the yellow stamens, which have no taste of their own.

Iranian trade names like negin, sargol and pushal (poushal) show up in export price lists,⁹ but none of the sources we opened defines them, so we won’t describe what each contains. The international standard, ISO 3632, grades saffron by measured color, bitterness and aroma, not by cut. See saffron for how it works.

Why the price invites fraud

At that price per gram, saffron is a magnet for adulteration. Katzer calls coating the threads with a non-volatile liquid to add weight very common, and notes that cruder fraud sells something that isn’t saffron at all.³ Our saffron page lists the adulterants documented in the literature and explains how the ISO test works.
