Vinous 95
A dense, succulent wine, the 2015 Cabernet Sauvignon captures all the raw power and density of the year. The 2015 is just starting to soften, but ideally it needs another few years in bottle to be at its finest. Readers should expect an especially opulent style, and yet the 2015 has more than enough depth to drink well for another 15+ years or more.-AG

This bottling reflects the past several years' fine-tuning the winery's vision in the vineyard and in the cellar. Including small amounts of Cabernet Franc, Petit Verdot, Merlot and Malbec, it's a rounded, concentrated wine that expresses the vintage with ripe, grippy tannins that beg for further resolution. Blackberry, clove and leather flavors rise to the fore. Cellar through 2035.-WE

James Suckling 94
Aromas of blackberry, chocolate and chili follow through to a full body, tight and chewy tannins and a linear finish. Shows polish and class. A blend of 92 cabernet sauvignon, 6 cabernet franc, 2 merlot. Very well done for the vintage. Try in 2020 but already attractive.-JS

Decanter 92
Owner Francis Ford Coppola has renamed his Cask Cabernet - second wine to Rubicon - and it's a fine drink for the money in the rarified air of Napa. Winemaker Chris Phelps used all five Bordeaux red grapes from seven vineyard blocks, and the wine is loaded with savoury spice, rich dark fruits and silky tannins. Cellar Rubicon and drink this while you wait. 50 new French oak.-DM

Robert Parker's Wine Advocate 92
Blended of 88 Cabernet Sauvignon, 6 Cabernet Franc, 5 Petit Verdot and 1 Merlot, the 2015 Cabernet Sauvignon is deep garnet-purple colored and features a boisterous nose of blueberry pie, blackcurrant cordial and Black Forest cake with suggestions of chocolate mint, potpourri, baking spices and cedar chest. Full-bodied and concentrated in the mouth, it has a solid frame of chewy tannins and just enough freshness to lift the densely packed fruit to a long finish.-RP
