Shafer Relentless is a full-bodied Napa Valley wine that offers a unique flavor profile.. The nose is filled with ripe dark cherry and blackberry aromas with hints of cedar, spice and anise. On the palate, big, bold tannins are balanced with a core of dark berry and currant flavors that are lifted by notes of forest floor, leather and sage. The finish is long and lingering, making this a perfect wine to pair with grilled meats, hard cheeses and hearty stews.
