One of the draws of botanical research, in my opinion, is the chance that you will discover something extraordinary, some intricate mechanism, adaptation, or chemical that has implications able to expand the scope of human knowledge. However, there are times when less information can be more exciting than a thorough chemical or physiological analysis. These are the instances where investigation into the mystery surrounding a plant actually reveals more about humans than the plant in question.

The basic recipe for beer goes something like this.You take starch from a cereal grain (the fruit of a domesticated species of Poaceae, or Grass family), use enzymes to convert that starch into sugar, feed the sugar to a microbe capable of fermentation (such as a yeast or bacteria), which then poops out alcohol and carbon dioxide. It’s a beautiful process. You see the barley – brewer’s yeast – hops combo all the time. But why be so predictable?
