Antonio "L.A." Reid, 53, is the chairman of the Island Def Jam Music Group, where he oversees the careers of such musical artists as Mariah Carey, Kanye West and the band Bon Jovi. He sits in the boardroom these days, but Reid got his start as a musician and songwriter. He and Kenneth "Babyface" Edmonds played in a band together before founding LaFace records, and the two have won Grammy awards for songwriting and production. Reid is also passionate about wine—he has a 2000-bottle cellar in his Long Island, N.Y., home. Reid recently spoke with Wine Spectator about blind tasting, cult wines and his dream of owning a vineyard.
