The Beardome project by Hydrocalypse Industries that I was part of a few years ago began to uncover some of the hidden microbiology of the beard:

I'm really interested in the connections between the microbes on our body and the practical microbes used in our food, particularly in cheese, and this brings it to a whole new level. Beardology is a very new field, perhaps this beer will inspire us to look deeper at what is lying beneath our beards.
