Duckhorn Vineyards has sourced grapes from this distinctive region for more than a quarter century and has crafted a Howell Mountain bottling since 1989. Recognized as one of the Napa Valley?s most acclaimed winegrowing regions, grapes from Howell Mountain are famous for producing age-worthy Cabernet Sauvignons with rich, deep color and excellent structure. To encourage further complexity, we bottle-age this mountain-grown wine one year longer than our other wines prior to release.
