I've wracked my brain to think of a better title than "A Brief History of Cheese". I don't think there is one.

The average American eats some 33 pounds of cheese per year, up from under 22 pounds in 1954. Cheese comes in some 2,000 varieties and has been around for some 4,000 years. The Science and Art of Cheese, a new microdocumentary from KQED, explores the rich and nuanced spectrum of this cultural fixation, from unraveling the secrets of cheese artisans, who hone the aesthetic and sensory attributes of fermented blocks of milk, to scientists who stick feta in the MRI in order to reduce its salt content without changing its texture.
