Grading of saffron is done through gauging Picrocrocin (flavor ), Crocin (color) and Safranal (aroma) content. This is done in the laboratory by ISO professionals. Note that the higher the number of these 3 factors means the higher the saffron quality. For your information, International Organization for Standardization or ISO is a global confederation of national standard giving bodies that set saffron classification based on the minimum prerequisites of every quality. This is referred to as ISO 3632.

Negin Saffron

Although Persian Sargol is considered as the premium saffron, there is another variation of Sargol Saffron. If three stigma threads are attached together and form a cluster, this type of saffron is called Negin. Since production of Negin saffron is an extremely precise manual skill, it is the most expensive type of saffron. The ISO reading of Negin is usually more than 270.

Sargol Saffron

This grade consists of ONLY dark red stigma tips and has the highest quality compared to the other types. Sargol saffron is the pure saffron with no broken stand and has the ISO reading of 260-270. Due to accumulation of saffron`s active components in stigmas, Persian Sargol has a very strong aroma and rich colouring capacity.

Pushal ( Mancha ) Saffron

Pushal saffron is the stigma part of the plant attached to a 1-3 mm style end. According to ISO 3632 system, this type falls into grade II category that has a color reading of up to 250. Although Pushal does not have Sargol’s pure texture and premium quality, but some consumers prefer to purchase Iranian Pushal to be assured of saffron validity and authenticity.

Bunch ( Dasteh or Dokhtarpich ) Saffron

This grade is relatively low strength grade (ISO reading is 70 to 75) and consists of red stigmata plus large amount of yellow style, presented in a tiny bundle.
