Peter Mondavi family. Napa Valley's first winery established in 1861. Our signature style Sauvignon Blanc preserves the vibrant flavors found in the fruit from the night it was harvested through the time this bottle is opened. Through delicate fruit handling and the use of stainless steel tanks, the aromas and flavors of guava, grapefruit and melon flavors shine through. Charles King, Napa Valley's first winery established in 1861, have been owned and operated by the Peter Mondavi family for three generations. Family tradition is the foundation of our winemaking and grape growing on our Napa Valley vineyard estates. Alc. 14.2% by vol.
