What saffron is — and what it is not
One flower.
Three threads.
Real saffron is made from the dried red stigmas of the autumn-blooming crocus. Its value begins with biology and continues through an exceptionally delicate harvest, careful drying and the protection of fragile aroma compounds.

It is notNot turmeric, paprika or safflower. Ground saffron also exists, but whole threads are easier to inspect.
Why rareEach blossom holds only three stigmas; harvesting and separating them takes patient handwork.
Saffron or safflower?
Similar names, different plants. Saffron is the red stigma of Crocus sativus; safflower is the dried floret of Carthamus tinctorius, a thistle-like plant. Both can colour food, but safflower has a much milder taste and does not give saffron’s distinctive aroma. Sometimes sold as “false saffron”, it is not a substitute for the same flavour.

Aroma · Taste · Colour
Three compounds.
One character.
Saffron's warm, floral aroma, golden colour and subtle bitterness can be understood through three defining natural compounds.
A naturally occurring glycoside associated with saffron's gentle bitterness — part of what distinguishes genuine saffron from colour alone.
A family of water-soluble carotenoid pigments that releases saffron's luminous golden colour into warm liquid. Crocin helps explain colouring power. It is one important measurement, but not a complete verdict on aroma, careful processing or origin.
Botanical origin
A plant shaped by human care.
Crocus sativus is sterile and cannot reproduce through seed. It is propagated vegetatively by dividing corms — season after season, field after field.
Where did saffron begin? Genetic research points to Attica, in Greece, where its wild ancestor, Crocus cartwrightianus, still grows. The cultivated plant was selected and passed from hand to hand long before anyone wrote down its story. There is no single recorded moment when the first saffron was “found”. Read the botanical research.
ContinuityIts survival and worldwide cultivation depend on human knowledge, selection and care.
Saffron in ancient culture
A flower in human hands, 3,600 years ago.
Around 1600 BC, artists at Akrotiri on Santorini painted women gathering crocuses and presenting their red stigmas to a seated goddess. Nearby, a young woman tends an injured foot. Some scholars interpret the scenes as a connection between saffron, healing and women’s lives. It is an interpretation, not a medical record — and one of the most evocative early images of our relationship with this flower.

Good saffron.
Open results.
Our ambition is simple: to produce saffron among the finest in the world, every year. Since we began producing saffron, every laboratory test of our saffron has achieved Category I. We publish the reports so you can see the results for yourself.
Understanding the categories
ISO 3632 assesses saffron against defined quality criteria. The 2025 specification includes Extra Class and Categories I, II and III. One useful comparison is the minimum colouring strength:
| Classification | Colouring strength |
|---|---|
| Extra Class | 230 |
| Category I | 200 |
| Category II | 170 |
| Category III | 120 |
These are standardised laboratory values, not percentages. Colour is only one requirement; the other applicable criteria must also be met. A high colour value alone does not reclassify an older report under the 2025 standard. Laboratory values give a useful, shared way to compare a tested batch. They do not replace sensory judgement, careful drying or a clear and traceable origin. ISO specification · Technical explanation and table (PDF)
Our latest published laboratory reports
These are the reports currently available to download. Each identifies the tested lot and the standard used; it is a record of that batch, not a promise made on colour alone.

Negin and Category I are not the same thing.
Negin describes a style of saffron thread and its selection. An ISO category describes measured quality. The cut tells you what you are looking at; the laboratory report tells you how the tested batch performed.
Tradition · Culture · Wellbeing
A little saffron.
A long human story.
For more than three millennia, saffron has belonged to more than the kitchen. It has coloured cloth, scented rooms, accompanied ceremonies and found a place in the apothecary. Across cultures, people turned to this precious flower for beauty, comfort and care.
Before perfume came in a bottle.
Ancient writers described saffron in fragrant preparations, ointments and scented spaces. Pliny recorded its use in perfumes and theatres in the Roman world. Imagine the warm scent drifting through a public gathering: its appeal was never only on the plate.
Stories of Cleopatra bathing in saffron are often repeated today. They belong to the flower’s popular legend, rather than to a firmly documented personal beauty routine.
A golden thread through daily life.
In Persian culture, saffron found a home in rice, sweets and fragrant drinks — and in medical traditions that associated it with cheerfulness and the heart. A valued ingredient could be nourishment, hospitality and a gesture of care at the same time.
These traditions tell us how people understood the plant. Their meaning goes beyond a list of ingredients: the occasion, the preparation and the person serving it all matter.
A chapter in the Canon.
In the eleventh century, Ibn Sina — known in Europe as Avicenna — discussed saffron in his Canon of Medicine. Historical uses included preparations connected with mood, digestion and women’s health. This influential book helped carry medical knowledge between cultures for centuries.
Such uses are part of saffron’s history, not instructions for treating yourself today. Old knowledge deserves to be remembered, including the context in which it was used.
Gold that came from a flower.
Long before modern colourants, saffron could lend a golden shade to textiles and other materials as well as food. Its expense made that colour special. In different places and periods, fragrance and colour became part of offerings, celebration and ritual.
The spice comes from the red stigmas. Purple petals are a different part of the flower; a history of using saffron should not automatically be read as a history of using its petals.
Precious enough to fight over.
In 1374, a merchant transport carrying saffron was robbed near Balsthal. The conflict associated with Neu-Falkenstein Castle became known as the Saffron War. It is a striking reminder of how much value people once placed on a small quantity of threads.
Today, transparent origins and laboratory reports tell a more useful story than extravagant claims about being “worth more than gold”.
Tradition still has a seat at the table.
Researchers today are studying saffron preparations in relation to mood and sleep, with promising results and questions still to answer. Many trials use measured extracts, not the small amounts of spice we cook with. They cannot be treated as interchangeable.
For everyday life, there is no need to turn a beautiful ingredient into a prescription. A fragrant meal, a warm drink, time shared with someone: saffron can be part of these small pleasures, without a promise attached.
Historical uses describe traditions, not proven treatments. Saffron as a culinary spice is different from a concentrated supplement. For supplements, pregnancy or questions involving medication, ask a qualified healthcare professional.
