Beringer's single vineyard Cabernets Sauvignon, each component parts of the distinctively excellent Private Reserve, are available only through direct VIP offerings from the winery. More interestingly, they are case studies in site specific terroir across Napa Valley. Bancroft Ranch, 1800 feet up the western slope of Howell Mountain, typically contributes the largest portion to the Private Reserve blend. The 2007, now in its prime, showcases unapologetically punchy black cherry and cassis, with ripples of dark chocolate and espresso intertmixted.
