In the other variety the stigmas are attached to the full-length style and tied in the form of a bunch of several hundred stigmas with their tong styles. This is known as Iranian Guchhi. The effective yield of stigmas from these bunches is just about 50% (Since the stigmas of Iranian Saffron are very short).
