More About Trefethen Eshcol Oak Knoll District Red Established in 1886, the historic Trefethen estate boasts a rich history, with its original winery facility erected within a grove of oak trees at the heart of Eshcol Ranch. Taking over production in the late 1960s, the Trefethen family pays homage to the estate's visionary founders by crafting a distinguished red blend sourced from the esteemed Eshcol Ranch Vineyard. Sustainability is an intricate part of the winery's philosophy, utilizing different cover crops to increase biodiversity and soil health. In addition, owls, bats, and hawks that live on the property serve as a natural pest control. The Eshcol Red features Cabernet Sauvignon and Merlot, with small additions of Petit Verdot, Malbec, and Cabernet Franc, with the percentages changing slightly each vintage. The 2021 release is an outstanding value for under $30, and its soft texture and approachability make it the perfect wine for any night of the week.
