How to Test if Your Saffron Is Real

By Sophie Dubois · September 28, 2026

Why Saffron Fraud Is Common

Saffron is the most expensive spice in the world, fetching up to 10 dollars per gram. This premium price makes it a frequent target for adulteration.

The Water Test

Place threads in warm water. Real saffron releases golden-yellow color slowly over 10-15 minutes. The threads remain red. Fake saffron dyes water red immediately.

The Taste Test

Real saffron tastes slightly bitter, not sweet. Sweet threads are likely coated with sugar to add weight.

The Smell Test

Authentic saffron has a distinctive honey-hay aroma. If it smells like nothing or has a chemical odor, it is likely fake.

The Baking Soda Test

Mix threads with baking soda and water. Real saffron turns the solution yellow. Pink or red means synthetic dyes.

The Grease Test

Press threads between paper. Real saffron leaves no greasy mark. Oil stains indicate glycerin treatment to increase weight.
