Dasteh saffron is the main and basic saffron types and is achieved by putting all part of saffron strands over each other and drying them. Normally length of style is about 3 to 5 mm and the stigma can be shorter or longer which determines the product quality. Embedding strands over each other can be one-way or two-way. In one-way embedding, similar parts should be on each other (style on the style and stigma on the stigma). In two-way embedding, styles should be on the middle and stigma on both sides. The second form is more attractive because only red parts (stigma) will be seen in both sides. Classification of saffron strands usually is done by women.

So Poushal saffron has more overall color which is between 170 to 250 units based on its quality.

Sargol saffron in fact is the saffron concept on the mind of most of people. In this type, style is removed completely and separated red stigma form pure saffron. So, Sargol is all-red type saffron. In some cases, “Poushal” also is known as “Sargol”. In this case saffron is divided into two types of “Negin Sargol” and “Momtaz Sargol”. Negin is refer to excellent and Momtaz is refer to prefer types. Negin Sargol is the same as mentioned Sargol saffron and the Momtaz contains some part of yellow style.

“Konj” or White Saffron
After removing “Sargol” from “Dasteh”, the root part of strands remain. This part is known as “konj” or “Sefid” Saffron in Iran. “Konj” is known as style or white in Europe. “Konj” is not a kind of saffron types but is considered due to its beautiful color and appearance. Some people incorrectly think that “konj” is more perfumed than the Sargol. Scientific studies show that valuable elements of saffron are only in its red stigma. These elements can transfer from stigma to the style due to move in plant tissue. More moisture in the style causes more aroma apparently.
