A bundle of dried vanilla beans, with a fresh, not yet fully matured fruit placed on top for comparison. The cylindrical pods, which can grow up to twenty-five centimeters long, change color from yellow to brown as they ripen. After harvesting, the pods are left to ferment by alternating exposure to sunlight with storage in sealed containers. During this process, they turn blackish, and the glycoside in the pod’s skin is broken down into fructose and vanillin. – 1990
