The aroma of saffron is strong and its taste is bitter and a little spicy. The bitter taste of saffron is related to a glycoside called Picrocrocin, which is a colorless monoterpenalide. The volatile essential oil of saffron is also responsible for its odor and aroma, which is produced by the separation of sugar from picrocrocin.
