95-Points by Robert Parker.
The 2014 Cabernet Sauvignon Reserve Spring Mountain (97% Cabernet Sauvignon and 3% Cabernet Franc, all sourced from their high-elevation vineyards on Spring Mountain) is the deepest, richest wine of the entire portfolio, with an opaque purple color and a super-pure nose of crème de cassis and blueberries. The wine is rich, full-bodied, nicely textured, and very long in the finish, with ripe tannins. It can be drunk now or cellared for another 15 or more years.
 
Robert Keenan Winery is a Napa Valley wine producer, located in the foothills of Mayacamas mountain range in Spring Mountain District. The estate produces a range of wines, focusing on the Cabernet Sauvignon and Merlot grape varieties.
The estate was originally planted in the 1890s to Zinfandel and Syrah, but the property was abandoned during Prohibition. It remained unoccupied until Robert Keenan purchased the estate in 1974. 
The Keenan family still owns the 69 hectare (170 acre) estate, about 19ha (48 acres) of which is planted to vines. The vineyards are farmed sustainably and planted to Chardonnay, Cabernet Sauvignon, Cabernet Franc and Merlot on Spring Mountain's steep, rocky mountainsides.
The estate's top wines, the Mernet Reserve, a blend of Merlot, Cabernet Sauvignon and Cabernet Franc, and the Reserve Cabernet Sauvignon, are both sourced from the estate vineyards.
