Saffron bunch, also called whole-grain saffron, is the mother of saffron because it contains the whole branch of saffron. This type of saffron, which is the main type of saffron in Iran, includes stigmas and white. These whole branches of saffron, which are taken from the stem, are put together in large numbers and packed in bunches. In this way, a beautiful shape and coloring of saffron is created by branch of saffron! White thread is used to wrap the branches because the chemical color of the chromatic threads is not transferred to the saffron strands. Of course, in some places, the strings are not tied with threads — this type is called open-bunch saffron.
