A blend of 66% Merlot, 29% Cabernet Sauvignon, 3% Cabernet Franc and 2% Petit Verdot, the 2017 D2 Proprietary Red Wine opens to a nose of dusty plum, silky cherry skin and black raspberry before showing hints of baking spice, dusty flower petals and baked earth. Medium to full-bodied, the wine is expressive and balanced across the mid-palate with lifting tannins and energetic acidity to make it food-friendly. Lingering flavors of cedar and sage persist in the mouth, as the wine stretches its legs on the winding finish,  highlighting the red berry frame. D2 has always been a crowd-pleaser, and the 2017 bottling continues that winning streak. The wine spent 20 months in French oak barrels (68% new) and then rested in bottle for  eight months.

Editor's Choice. Merlot makes up two-thirds of this wine, with the rest Cabernet Sauvignon along with bits of Cabernet Franc and Petit Verdot. The aromas are unique, with notes of bittersweet chocolate, cedar, black  tea, and raspberry. The palate is sleek in style, filling in over time, bringing a lovely sense of finesse and balance. Bright acidity ups the interest. Give it some time in the cellar to see it at its best.
