Saffron is the most precious spice in the world. Taken from the red crocus flower, 150,000 crocuses need to be collected manually to collect 1 pound of crocuses. At the end of October each year, saffron is collected by hand in a ritual-like manner following the tradition that had existed 3,500 years ago. ISO3632 rated Krokos Kozanis' saffron as the world's highest grade. All saffron tea drinks are caffeine-free.
