In order to create a blend that highlights the outstanding terroir of Beringer’s many Napa Valley vineyards, each vineyard lot is kept separate from the moment the grapes were harvested until final blending. In creating Quantum, the goal is to showcase an interesting mix of varietals using the foundation of Cabernet Sauvignon — the backbone of the Beringer portfolio. Approximately half of the blend comes from Howell Mountain with the balance made up of a selection of notable vineyard sites along the valley floor. The Merlot contributes round mouthfeel and soft tannins, Cabernet Franc adds great color and unique aromatics, Petite Sirah adds spice complexity, and Malbec adds silkiness and color to the final blend. The wines were aged in French oak (31 percent new barrels) for 20 months, and then in bottle for six months.
74% Cabernet Sauvignon, 12% Merlot, 7% Cabernet Franc, 5% Petite Sirah, 2% Malbec.
