In this captivating book, Stewart Lee Allen treks three-quarters of the way around the world on a caffeinated quest to answer these profound questions: Did the advent of coffee give birth to an enlightened western civilization? Is coffee, indeed, the substance that drives history? From the cliffhanging villages of Southern Yemen, where coffee beans were first cultivated eight hundred years ago, to a cavernous coffeehouse in Calcutta, the drinking spot for two of India’s three Nobel Prize winners . . . from Parisian salons and cafés where the French Revolution was born, to the roadside diners and chain restaurants of the good ol’ U.S.A., where something resembling brown water passes for coffee, Allen wittily proves that the world was wired long before the Internet. And those who deny the power of coffee (namely tea-drinkers) do so at their own peril.
