Each bottle of Clase Azul is a work of art. Hand sculpted and individually painted, no one bottle is exactly alike. Clase Azul tequilas are 100% from organic Tequilana Weber Blue agaves. Of about 200 breeds of agave, this one is the only one that produces tequila; and once it was harvest, Clase Azul elects to cooked them in old-fashioned brick ovens, which takes 72 hours.
