The 2017 Stack House Cabernet Sauvignon bursts from the glass with an intense plethora of dark brooding fruits including black currant, blackberry pie, black cherry and huckleberry compote. Following the fruit, layers of crushed volcanic rock, wet earth, toasty oak, baking spice and black pepper emerge. This full-bodied wine exhibits vibrant acidity, massive structure and an everlasting finish, all characteristic of the beautiful warm low yielding vintage. Composed of almost all hillside fruit, this is an amazing value of Napa Valley Cabernet Sauvignon.
