The brewing of beer is not only humankinds oldest biotechnology, it is likely the basis of static civilization and also a major factor in the survival of the species. Even if you think that is a tad exaggerated, there is absolutely no doubt that beer represents the most exquisite convergence of diverse sciences (botany, plant physiology, chemistry, biochemistry, microbiology, chemical engineering and more) in pursuit of a product that is as complex as it is delightful. Beer has a proud history as a dietary imperative in many societies.
