The Ink Grade Estate Vineyard claims a view unbeknownst to most in the Napa Valley, lying in the northeast corner of the Howell Mountain AVA. Terraced throughout due to the extreme slopes, this mountainside vineyard clings to volcanic “tufa” soils. Ink Grade Estate possesses a raw tension that renders fruit of immense intensity and depth. If ever there was a site that imparted a feeling of reverence, Ink Grade is such a place.
