Duckhorn Wine Company originally created Paraduxx to allow its winemakers the opportunity to explore other styles without detracting from Duckhorn Vineyards' focus on Bordeaux varietals. In 1994, Paraduxx sourced four tons of Zinfandel from the 100-year-old vines of Napa's Korte Vineyard. This Zinfandel was blended with Duckhorn Vineyards' own Merlot, Cabernet Sauvignon and Petite Sirah to create the first Paraduxx vintage. Since then, Paraduxx has grown to include grapes from the Rector Creek Vineyard in Yountville, which benefits from well-drained rocky alluvial soils and Napa's temperate climate. The winemaking team has been so pleased with the fruit from Rector Creek that Paraduxx has used this Zinfandel as the basis for the development of its proprietary red.
