Winemaker Notes
The 2020 Silver Oak Alexander Valley Cabernet Sauvignon has captivating notes of cedar and concentrated red fruit character that dance gracefully on the palate. With its ruby hue and smooth, polished tannins, this wine offers a harmonious blend of depth and nuance. Balanced acidity adds a refined touch to the long finish, with vibrant layers of fresh raspberry, cherry and cola. This wine will continue to improve through 2042 given proper cellaring conditions.

Silver Oak's 2020 releases of Napa and Alexander Valley Cabernets are downright impressive. Tasted four years after the fires, in September of 2024 at the Alexander Valley winery, neither wine showed any sign of the hardened tannic structure or overwrought fruit often associated with the vintage. Instead, these wines remain true to Silver Oak’s signature style, with blackcurrant, fig, and plum fruits layered with white pepper, sweet cedar, and coriander spice. Medium-bodied, with sculpted tannins that persist through the lengthy finish, the Alexander Valley Cabernet in particular retains all the hallmarks of a balanced, inviting, and vibrant Silver Oak red.

Truly gorgeous, fruity, velvety and enjoyable for a full-bodied cabernet. It is rich in blueberries, cherry cream, black cherries and raspberries on the palate, with very smooth, layered tannins and a soothing mouthfeel.
Family-owned for 50 years, Silver Oak produces Cabernets aged exclusively in American oak. Its exceptional, food-friendly wines are both drinkable upon release and worthy of cellaring for decades to come. Ray Duncan founded Silver Oak with Justin Meyer in 1972, and it’s now owned and operated by Ray’s sons, David and Tim, with a commitment to innovative and sustainable viticulture practices across its vineyard properties, winemaking facilities, tasting rooms and cooperage. Silver Oak Alexander Valley has been called the world's greenest winery by The San Francisco Chronicle. Constructed between 2012-2018 the winery was built around the production of just one wine: Silver Oak Alexander Valley Cabernet Sauvignon, a staple of restaurant lists nationwide for more than 45 years. Featuring panoramic views of Silver Oak’s 70 acres of prime Cabernet Sauvignon vineyards and surrounding 115-acre estate, the historic property features excellent volcanic soil profiles set amidst the rolling bench lands of Northern Sonoma County.
A noble variety bestowed with both power and concentration, Cabernet Sauvignon enjoys success all over the globe, its best examples showing potential to age beautifully for decades. Cabernet Sauvignon flourishes in Bordeaux's Medoc where it is often blended with Merlot and smaller amounts of some combination of Cabernet Franc, Malbecand Petit Verdot. In the Napa Valley, ‘Cab’ is responsible for some of the world’s most prestigious, age-worthy and sought-after “cult” wines. Somm Secret—DNA profiling in 1997 revealed that Cabernet Sauvignon was born from a spontaneous crossing of Cabernet Franc and Sauvignon Blanc in 17th century southwest France.
Nearly a northern extension of Napa Valley, Alexander Valley starts just north of the small, Knights Valley, and is just a few minutes drive from the Napa town of Calistoga. It is Sonoma County’s hottest AVA. But the Russian River, which runs through the valley, creates cooler pockets and its soft, alluvial soil is ideal for grape growing, especially Cabernet Sauvignon. In fact, some believe that Alexander Valley Cabernets truly rival the best from Napa Valley and many of the heavy-hitter producers have largely invested here.
In addition to Cabernet Sauvignon, which makes up over 50% of plantings, Merlot and old vine Zinfandel thrive here. Ample, fleshy Chardonnay and Sauvignon Blanc dominate white wine production. Some old-vine plantings of Grenache have also been discovered and more recent experiments with Sangiovese and Barbera show great promise.
