Certified by California Sustainable Winegrowing Alliance, Napa Green Vineyard & Winery, Bay Area Green Business, and Fish Friendly Farming, Domaine Carneros was founded by the Taittinger family in 1987 within the Carneros AVA with the conviction that the finest méthode traditionnelle sparkling wines begin with the healthiest land, and earlier this year, the producer received the Sustainable Business of the Year award from the Napa Chamber of Commerce, presented by MCE Clean Energy. “When we installed our first solar array two decades ago, we were at the forefront of renewable energy adoption in the wine industry,” notes CEO Remi Cohen. “Today, our advanced microgrid technology represents the next generation of energy independence and environmental stewardship. As climate challenges intensify, Domaine Carneros continues its commitment to caring for the land as intentionally as we care for our wines, reducing our carbon footprint and raising the bar on renewable energy.”
In partnership with Schneider Electric, Domaine Carneros deployed the EcoStruxure Microgrid in 2023, doubling the winery’s energy generation capacity via the integration of 614 upgraded solar panels; in addition to ensuring uninterrupted operations during increasingly common power outages due to wildfires and severe weather events, the system stores excess solar energy generated during the day for use in the evenings or early mornings during peak demand. It also powers four electric vehicle charging stations for guests, seamlessly integrating green technology throughout the visitor experience.
Domaine Carneros also recycles and reuses water used in production to irrigate estate vineyards; practices integrated pest management with owl boxes and beneficial cover crops; reuses 25% of packaging materials annually, saving over 1.2 million pieces since 2010; implemented lighter-weight bottles to reduce shipping impacts; and launched on-site grape pomace composting trials in 2025, among other practices. Its comprehensive approach to sustainability has earned the winery numerous prestigious recognitions, including the aforementioned 2025 Napa Chamber of Commerce Sustainable Business of the Year; the 2025 RISE Leadership Award for Energy Efficiency and Savings; the 2024 City of Napa Leadership Recycling Award; and the 2023 RISE Leadership Award for waste prevention and supply chain greening.
“Domaine Carneros was built on a Taittinger family tenet, rooted in their legendary commitment to estate ownership, that the finest wines begin with the healthiest land,” says Cohen. “That belief drives every decision we make in the vineyard and beyond, from how we manage water and energy to how we think about our responsibility to this land and our community.
