Each distinctive lot is kept separate from the moment of harvest until final blending the following year. Each Quantum expression showcases traditional Bordeaux varietals with a foundation of Cabernet Sauvignon, the backbone and undisputed star of Beringer. In this vintage, the blend anchors with 69% Cabernet Sauvignon, with Cabernet Franc and Petit Sirah highlighted, along with touches of Malbec, Merlot and Petit Verdot. Merlot contributes to a round mouthfeel and soft tannins, Cabernet Franc adds great color and unique aromatics, Petite Sirah adds spice complexity, and Malbec adds silkiness and depth of color to the final blend. The wines were aged in French oak (50% new) for 20 months, and allowed to further integrate and gain complexity in bottle for another year.
