Founded in 1861 by Charles Krug, the 27-year old Prussian immigrant came to America with little besides willpower and a willingness to work hard to build the cornerstone of the first winery in the Napa Valley. In 1943, Cesare Mondavi, purchased the winery. At 60 years old, Cesare Mondavi spearheaded a dramatic renaissance in the decade that followed. in 1976, Peter Mondavi became President of the winery. Above all else, Charles Krug Winery is a family winery. Peter Sr. and his sons Marc and Peter Jr. continue their dedication to producing the finest Bordeaux style wines in the Napa Valley.
