About The Wine

Addendum is the Fess Parker family's Napa Valley project. Having built its name on highly regarded Burgundian and Rhône varietals in Santa Barbara County, the family's second generation expanded on Fess's vision — leveraging long-term relationships with committed Napa growers to create a limited, stand-alone collection of Bordeaux-varietal wines sourced from some of the most prestigious and established vineyard holdings in the Napa Valley.

The Stags Leap District is one of Napa's most celebrated AVAs — a small, rocky corner of the valley's eastern edge famous for Cabernets that pair power with polish: lush dark fruit, velvety tannins, and remarkable aromatic lift. Wines from this tiny district routinely command well over $100 a bottle.

2021 was a stellar, low-yield vintage in Napa Valley. A dry winter and a moderate growing season produced small berries with extraordinary concentration — a vintage critics rank among the valley's best in recent memory. Wine Enthusiast rated this bottling 93 points and Jeb Dunnuck awarded it 95.

Cabernet Sauvignon from the Stags Leap District of Napa Valley. 14.9% ABV.

A deep, full-bodied Cabernet layered with black cherry, ripe plum, and sweet oak spice.

Fine-grained tannins and fresh acidity carry a long, brooding finish — delicious now and built to reward cellaring into the 2030s.

CRITIC REVIEWS

What the Critics Said

The 2021 Cabernet Sauvignon Stags Leap District is 100% Cabernet Sauvignon from the Clos Du Val Vineyard, aged 21 months in French oak (70% new). Deep ruby/purple-hued, it has a gorgeous nose of cassis, darker, almost blue fruits, classy oak, violets, and floral nuances. It's medium to full-bodied with ultra-pure fruit, fine-grained tannins, and a superb finish. This wine shows the incredibly impressive style of the vintage and will shine for two decades, not as a blockbuster, but for its balance, purity, and grace. Drink 2025-2045. ~ 95 Jeb Dunnuck

Black cherries and plums, layered with oak spices are carried by fine grained tannins and pert acidity through a long, brooding finish. Full-bodied and full of flavor. ~93 Wine Enthusiast

The 2021 Cabernet Sauvignon Stags Leap District is a pretty, savory wine with tons of site character. Black cherry, plum, licorice, dried herbs, sage, menthol and incense open nicely with some coaxing. There's good depth and complexity in this Cabernet from Clos du Val's Hirondelle Estate. ~92 Vinous Media
