Marc, Peter Mondavi Sr. and Peter Mondavi Jr.
Cesare Mondavi emigrated from Marches, Italy in 1906, to Minnesota and worked in the iron mines. In 1908, he returned to Italy to marry Rosa Grassi and settled in Virginia, Minnesota where they operated a boarding house and saloon. Four children were born to the couple: Mary, Helen, Robert and Peter. In 1922, at the beginning of Prohibition, the family journeyed to Lodi, California where Cesare built the lucrative grape and fruit shipping business, C. Mondavi & Sons.
Peter attended Stanford University, graduating in 1937, going on to pursue graduate studies in enology at University of California, Berkeley. He later served in the U.S. Army during World War II before returning home to help run the winery.
Peter Mondavi has effected tremendous enological, viticultural and marketing innovations over six decades, including:
- Vintage dating varietal wines
- Cold fermentation for white wines
- Cold sterile filtration
- Fermentation in small French oak barrels and glass-lined tanks
- The first winery newsletter "Bottles & Bins”, initially published in 1949
- The annual Tastings on the Lawn concert series, started in 1951
Since the early 1980s, Peter's two sons, Marc and Peter Jr., educated at UC Davis and Stanford respectively, have assumed major roles at Charles Krug Winery. Both Marc and Peter Jr. are active in all aspects of viticulture, winemaking and marketing. Peter Mondavi Sr. remains active in the day-to-day winery operation, although he is increasingly relying on his sons and the fourth generation to determine the winery's vision.
