Keenan is a Spring Mountain stalwart, with their estate vineyards perched in the cooler, rocky hills above the Napa Valley floor. The fruit here gets stress and concentration from gravelly soils and steep slopes, and the Napa Cab leans on that mountain backbone. The 2021 is generous and structured, with dark fruit and savory spice framed by 20 months in French and American oak. A classic Spring Mountain Cab built to drink well now and over the next decade-plus.
