History
In 1899, 12-year-old Louis M. Martini set out from Genoa to work for his father's seafood business in San Francisco. He later moved to Napa Valley in 1933, where he built his winery, becoming one of only five winemakers to do so at the Repeal of Prohibition. He selected Napa for its unmatched grape quality and recognized Cabernet Sauvignon as the most promising variety. He taught the business to his son, Louis Peter, who continued the family legacy of advancements in winegrowing and winemaking. Today's leadership is under Michael Claypool.
