Among the other species, we shall put emphasize on Sargol saffron, which has the best quality. It has no style and is universally known as all red. It is similar to coupe saffron. While picking Poushal saffron the stigma and often part of style is separated from the flower. So, due to its straw shape it is named Poushal (straw) saffron.
All the above species of saffron can have first, second and third quality. No type can be preferred to the others. Just the stigmas purity and its ratio to the style can present a qualifying criterion. Obviously, in similar situations Sargol and Poushal saffron are better and more valued than the others.
It is necessary to note that in bunch saffron, the root is supposed to have the saffron fragrance but the experiments and analyses show that the origin of the flavor and other valuable substances is in the red stigma. These substances-especially crocine – are transferred from the style to the stigma, but as there is much moisture in the style, it seems that the flavor shall be in it.
The yellow part neither has the main saffron substances nor even possesses crocine. Its flavor is due to the moisture in it. However, as a result of its beautiful appearance and the fact that it can not be cheated, most people pay attention to it as well.
