In 2002, Rudy Kurniawan, an unknown twentysomething, burst into the privileged world of ultrafine wines. Blessed with a virtuoso palate, and with a seemingly limitless supply of coveted bottles, Kurniawan quickly became the leading purveyor of rare wines to the American elite.

Journalist Peter Hellman was there, and he began to investigate: Were the bottles fake? Were there others? And was Kurniawan himself a dupe . . . or had he ensnared the world’s top winemakers, sellers, and drinkers in a web of deceit?
