Robert Gerald Mondavi was an American winemaker. His technical and marketing strategies brought worldwide recognition for the wines of the Napa Valley in California. From an early period, Mondavi promoted labeling wines varietally rather than generically, which became the standard for New World wines. The Robert Mondavi Institute (RMI) for Wine and Food Science at the University of California, Davis opened in October 2008 in his honor.
