• A Look Inside Our Alexander Valley Winery

A Look Inside Our New Alexander Valley Winery

Built on a historic 113-acre property with breathtaking views and excellent soil profiles for growing high-quality Cabernet Sauvignon, our state-of-the-art Alexander Valley winery is the second flagship Silver Oak winery built by the Duncan family.

It’s All About the Wine

The property was originally deeded in 1877 to Cyrus Alexander, namesake of the Alexander Valley, who first established the land as one of the finest vineyard sites in Sonoma County. Today, the vineyard is planted to 75 acres of Cabernet Sauvignon and forms the backbone for our Alexander Valley Cabernet Sauvignon.

Our winemaking and sustainability teams performed extensive research to design the winery around the production of just one wine, our Alexander Valley Cabernet Sauvignon, including tank size and arrangement, thermal protected crush pad, steam barrel washing facilities, solar panel systems, as well as water reclamation and re-use systems. All in pursuit of exceptional Cabernet.

Framing the Vineyard

Our design theme for the new winery is Framing the Vineyard, in order to feature the rolling topography of Alexander Valley from every point on the property and to bring our guests into the winemaking process from vineyard to cellar. Heading up the design team was lead architect Daniel Piechota of Piechota Architecture, best known for striking residential and commercial work throughout Northern California. The modern barn concept drew inspiration from the historic barns of the Alexander Valley, creating a striking balance between traditional materials and modern design.

Building Materials

More than 3,000 building materials and equipment choices were carefully vetted for harmful and commonly found “red list” chemicals. Reclaimed redwood siding on the winery and tasting room was salvaged from old wine tanks built by Cherokee Winery in the 1930s, then and later disassembled by Robert Mondavi when he purchased the brand. Oak flooring, as well as wall and ceiling paneling in offices and the tasting room were sourced from naturally felled valley oak trees that required removal for safety.

Air Quality

Everything inside that commonly emits volatile organic compounds (VOCs), such as paint, flooring, insulation, and furniture were all tested for emissions. After construction was completed, a thorough cleaning and airing out of the building took place before indoor air quality samples were taken and analyzed.


Leadership in Energy and Environmental Design (LEED)

In 2016, our Oakville winery became the world’s first LEED Platinum production winery for Existing Buildings, Operations and Maintenance (EBoM). In 2018 our Alexander Valley winery received LEED Platinum certification for Building Design and Construction (BD+C). The two Silver Oak wineries are the world’s first wineries to achieve each of these certifications.

Living Building Challenge

The Living Building Challenge (LBC) is the world’s most rigorous performance standard for buildings, featuring a regenerative design framework for spaces that give more than they take. We are seeking LBC Certification for all seven petals: Place, Water, Energy, Health & Happiness, Materials, Equity and Beauty.
