Innovations

Since our founding in 1861, Charles Krug Winery continues to make significant contributions to winemaking techniques. From our early days when Charles Krug used a cider press to make wine to Peter Mondavi Sr.'s groundbreaking cold fermentation research, we continuously strive to improve our approach to winemaking, ensuring each bottle of wine we craft meets our standards of unparalleled quality.

Brothers Robert and Peter Mondavi Sr. were among the founding members of the Napa Valley Technical Group. Formed to share knowledge and information with fellow vintners, it was the origin of what is today known as the Napa Valley Vintners.

That same year, Charles Krug Winery was among the first California wineries to promote vintage-dated varietal wines.
