How to Spot Fake Saffron

Saffron is the most expensive spice in the world by weight, which is exactly why it’s one of the most commonly adulterated. Here’s what to actually check before you trust a batch, whether it’s ours or anyone else’s.

Look at the threads

Genuine saffron threads are trumpet-shaped: narrow and rolled at one end, flaring out slightly at the other, with a slightly frayed, uneven edge. They’re deep red along most of the thread, often shading to a lighter orange or yellow at the very tip (that tip is the stigma’s style — its presence is actually a sign of quality, not a flaw). Threads that look perfectly uniform, flat, or razor-cut are worth a second look.

Smell before you taste

Real saffron smells sharp, slightly metallic and hay-like, with a bitter edge — not sweet or floral. Safflower (“bastard saffron”) and dyed corn silk, the two most common substitutes, smell faintly of straw or nothing at all.

The water test

Drop a few threads into a cup of lukewarm water and leave them undamaged. Real saffron releases its colour slowly — the water turns a warm golden-yellow over 10–15 minutes, and the threads themselves stay largely intact and red. If the water turns bright red or orange within seconds, that’s dye, not saffron: genuine threads simply don’t release colour that fast.

The rub test

Rub a thread between your fingers. Real saffron leaves a faint yellow-orange stain and a slightly oily residue — it won’t crumble to dust or vanish like paper. Threads made of dyed corn silk or paper shavings tend to disintegrate or leave no trace at all.

Price is a signal, not proof

Genuine Kashmiri Mongra saffron is graded and priced accordingly — if a “great deal” price looks too good against the going rate for ISO 3632 Category I saffron, treat that as a warning sign rather than a bargain.

Every pack we sell carries a harvest year and a lot number so you can trace it back to the grower. If you’d like to understand how that works, see our lot lookup page, or get in touch and we’ll walk you through the batch you have.
