Professional journalist and amateur drinker Bianca Bosker didn’t know much about wine --- until she discovered an alternate universe where taste reigns supreme, a world of elite sommeliers who dedicate their lives to the pursuit of flavor. Astounded by their fervor and seemingly superhuman sensory powers, she set out to uncover what drove their obsession, and whether she, too, could become a “cork dork.”

With boundless curiousity, humor and a healthy dose of skepticism, Bosker takes the reader inside underground tasting groups, exclusive New York City restaurants, California mass-market wine factories, and even a neuroscientist’s fMRI machine as she attempts to answer the most nagging question of all: What’s the big deal about wine? What she learns will change the way you drink wine --- and, perhaps, the way you live --- forever.
