Humans have been perfecting alcohol production for ten thousand years, but scientists are just starting to distill the chemical reactions behind the perfect buzz. In a spirited tour across continents and cultures, Adam Rogers takes us from bourbon country to the world’s top gene-sequencing labs, introducing us to the bars, barflies, and evolving science at the heart of boozy technology. He chases the physics, biology, chemistry, and metallurgy that produce alcohol, and the psychology and neurobiology that make us want it. If you’ve ever wondered how your drink arrived in your glass, or what it will do to you, Proof makes an unparalleled drinking companion.
