There are many factors that can help you identify the quality of saffron. People believe that a good quality saffron offers decent coloring capabilities and it also has a pleasant aroma. The coloring capabilities of saffron come from its thread’s red portion and not the yellow one because the yellow portion is the one that is left uncut in a lower grade saffron. This means that a good quality saffron is the one which has good coloring strength and that is entirely red. This important criterion is actually very important but this will not suffice the entire quality of having good quality saffron.
The next important criterion to distinguish if saffron is of good quality is its aroma. Old saffron loses its aroma and sometimes an old saffron has an unpleasant smell. Although red saffron is the mostly preferred ones, you have to keep in mind that this does not necessarily mean that the saffron strand with some yellow is not decent and of poor quality. In fact there are some people who prefer saffron with yellow in it. moreover, you have to bear in mind that good quality and fresh saffron is less than 1 year old and this can be more beneficial for you.
