The Grading School · Real or fake
Prove it atyour own sink.
Three threads, a glass of room-temperature water, ten minutes. Real saffron colours the water slowly and the thread stays red. A dye does the opposite, and cannot help itself.
Chapter 01 · The test
How do you tell if saffron is real?
Drop three threads into still, room-temperature water and wait ten minutes. Genuine saffron releases a golden amber slowly, in visible ribbons, while the threads stay stubbornly red. Dyed fakes and safflower flood the water red or orange within seconds and the threads go pale, because their colour was painted on, or never belonged to saffron at all.
- 01 · Drop
- Three threads into still water. No stirring; stirring hides the evidence
- 02 · Wait
- Ten minutes. Make tea. Do not touch the glass
- 03 · Read the water
- Slow golden amber, arriving in ribbons: genuine.
Instant red or orange cloud: dyed or fake - 04 · Read the thread
- Still deep red, still trumpet-shaped: genuine.
Gone pale or fallen apart: not saffron
Room-temperature water makes the difference easiest to see; heat just speeds everything up. This catches dyed threads and the common fakes. It cannot catch blends, powder or added weight; that is what laboratory reports are for.
Chapter 02 · Four more, free
What else can you check without a laboratory?
The water test catches dye. These four catch most of the rest, and they take about forty seconds between them.
Wet a thread and rub it between two fingers. Real saffron stains the skin gold, not red, and the thread holds together. Dyed paper and many fibre fakes disintegrate; a red smear means dye.
Catches fibre fakesReal saffron smells of hay. Nothing at all, or a sharp perfume, are bad answers.
Catches scented fakesTip the jar onto a white plate. A stigma is a trumpet: frayed and open at one end, narrowing to a point at the other. Flat ribbons and identical strands with no flared tip are telling you something was manufactured, not grown.
Catches safflowerDry saffron whispers against glass. If the threads feel damp or sticky, or clump in the corner of the jar, they may have been weighted with syrup or oil, a fraud that sells you syrup or oil at the price of saffron.

What should the label tell you?
Most of the decision can be made before you buy, because the things a good house prints are precisely the things a bad one leaves off. Five fields. If a label is missing three of them, put it down.
And one question, asked out loud: “Can I see the ISO 3632 report for this lot?” The reaction is the answer. A house that has one will produce it; a house that does not will explain why the question is unusual, and either way, you have learned what you need to know.
What the certificate proves, and what it does not
ISO 3632 measures colouring, taste and aroma strength. It is mainly a measure of power. It checks for synthetic dyes and visible foreign matter, but it is weak at catching other plants. Published work has found that the standard's spectrophotometric method does not reliably detect adulterants such as safflower or turmeric below roughly ten to twenty per cent of the sample. A certificate is necessary and it is not sufficient, which is why the glass of water still matters, and why the test card ships in every one of our boxes.
Chapter 04 · The cheapest tell
What does a suspiciously cheap gram mean?
A gram of saffron is roughly a hundred and fifty flowers, each opened by hand. That labour does not get cheaper quietly. So when a gram is priced far below everything around it, the saving has to have come from somewhere, and there are a few places it usually comes from: a lower grade sold under a higher name, the pale style left on to add weight, added moisture or syrup, or material that was never in a crocus at all.
Few of those are obvious at a glance, which is why the testing matters more than the price tag.
Chapter 05 · If it fails
What should you do if the test fails?
01Take it back, and take the glass with you
A photograph of red water beside pale threads is a difficult thing to argue with. Many sellers refund rather than discuss it. Keep the packaging: the batch or lot number is what lets anyone investigate further.
02Report it, if it was sold in Abu Dhabi
Food sold in Abu Dhabi falls under the Abu Dhabi Agriculture and Food Safety Authority, and adulterated food is their business, not just a private disappointment. A complaint with a lot number and a photograph is worth more than a review.
03Do not grind it and hope
Grinding a failed sample destroys the only evidence you have and puts an unknown dye into your food. Published analyses of fake saffron have turned up industrial dyes and, through DNA testing, plant material ranging from marigold to meadow grass. Whatever it is, it is not honest saffron.
