94-Points by Robert Parker & Wilfred Wong.
The 2019 Cabernet Sauvignon Mountainside has a deep garnet-purple color, bursting with bold scents of black cherries, mulberries and warm cassis, plus hints of fragrant earth and cedar. Full-bodied, intense and possessing bags of fresh, lively black fruits, it has a firm structure of grainy tannins, finishing long with a spicy kick.
Blend: 77% Cabernet Sauvignon, 19% Merlot, 4% Cabernet Franc.
 
The founding Acumen team of winemaker Denis Malbec and viticulturists Garrett Buckland were drawn to the mountainside vineyards of Napa Valley's eastern slopes, which have created countless world-class wines. It was here in the rugged Atlas Peak AVA where they set their roots in two unique vineyards with a total of 116 organically farmed acres. The Acumen labels share a glimpse of the inspiring views from their vineyards, both of which have an Old World feel, with bucolic rolling hills and textured rows of mountainside grapevines, surrounded by chaparral and sagebrush.
Denis Malbec, a winemaking artist, inspiration and good friend, was born and raised amidst the vineyars and cellar of Chateau Latour, a Bordeaux First Growth in the Pauillac commune of the Medoc. He was Acumen's first winemaker and together with Henrik Poulsen made the Acumen wines through the 2015 vintage. Tragically, in early 2016 he passed away in a car accident. He will be greatly missed and warmly remembered, with the 2013 and 2014 Acumen PEAK wines to bear a subtle tribute on the label in his honor.
Acumen lives their belief that the world's best wine are grown in the vineyard, so they feel very fortunate to have their vineyards and winemaking so thoroughly united under the artistry and expertise of  Phillip Titus and supported by their amazing full-time vineyard and winemaking team.
