Buy from reputable, well-reviewed sellers
Check for a strong, distinct aroma
Look for deep red threads with slightly orange tips
Avoid saffron that looks too uniform or dyed
Rub a thread on damp white paper; it should not bleed color quickly
Soak a few strands in warm water; authentic saffron releases color slowly
Taste a small amount; it should be slightly bitter, not sweet
Inspect for dry, trumpet-shaped stigmas
Prefer whole threads over powdered saffron
Check origin and harvest details on the label
Compare price; very cheap saffron is often fake
Look for lab testing or certification
Store in an airtight container away from light and moisture
