More than 6,500 acres span the Rutherford region, with most of the terrain planted in Cabernet Sauvignon grapes. The heat and dryness in the Rutherford region allows the grapes here to mature more than in other regions; which results in tannins that are more deeply developed. As a result, the Cabs produced in Rutherford have the ability to stand up to decades long aging. There are also varietals planted; however, including Cabernet Franc, Merlot, Petit Verdot and Malbec.
