The proprietary red wine blend has always been dominated by Cabernet Sauvignon, but it includes other Bordeaux varieties as well. It is kept 22-24 months in 100% new oak. The 2015 Proprietary Red Wine, a blend of 79% Cabernet Sauvignon, 16% Merlot and the rest Malbec, Petit Verdot and Cabernet Franc, has super concentration, a massive mouthfeel, heady, intense flavors of black and blue fruits, chocolate, wood spice and barbecue notes. It is a killer effort and, as so many of the 2015s, another magnificent vintage for Northern California.
