Vanilla Origins, Terriors, Aromas, Chemical Composition and other interesting facts

Did you know that vanilla is one of the most complex flavors on the planet.

It is also (other than saffron) the most labor intensive crop.

Everyone at this point knows the history of vanilla, but does everyone understand the immense differences chemically and aroma/flavor wise?

The more I learn, the more I understand how little we know about this amazing fruit of the orchid!!
