With boundless curiosity, 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.
