Highest quality saffron on the market from La Mancha, Spain. The La Mancha region of Spain is famous for its high quality saffron that is used to give flavor, aroma and color to many wonderful traditional dishes, including the increasingly popular paella! The important factor in determining quality is a saffron’s power of coloration. According to the iso norms, grade 1 saffron has a power of coloration above 190 upc (units of power of coloration). Matiz España, used by the world-renowned chef Ferran Adria, regularly tests at over 240 upc. This pure Spanish saffron is packaged in beautiful recycled glass jars and hand-sealed with wax.
