St. Supéry Estate is the winner of the Green Medal LEADER AWARD, given to the vineyard or winery that excels in the three “Es” of sustainability — Environmentally sound, socially Equitable and Economically viable practices.
St. Supéry Estate Vineyards & Winery blends environmental stewardship with a deep commitment to their community. A leader in climate action, they have transitioned to Gold membership with International Wineries for Climate Action and reduced their emissions intensity by 48% since 2021. Their water management is equally rigorous, achieving a 56% reduction in usage while recycling all process water for landscape irrigation. With over 1,600-acres in Napa Valley, biodiversity thrives; 1,000 acres of the land remains wild, supported seasonally by 900 grazing sheep that provide natural fertilization, fire prevention and reduce the number of tractor passes. As a founding member of the North Bay Zero Waste Collective, St. Supéry serves as a regional recycling hub, diverting over 590,000 pounds of material from landfills since 2024. They support their employees through carpool incentives and naturalization assistance and the broader Napa community by participating in the Napa Food Project, which collectively donated over 21,000 pounds of food in 2025. Sustainability is also central to wine promotion, with practices and certifications touted to both trade and consumers. This 2026 recognition builds upon a long history of excellence, including being honored with the California Green Medal Environment Award in 2018. For their innovative leadership in the three pillars of sustainability, St. Supéry Estate Vineyards & Winery is the winner of the 2026 California Green Medal Sustainable Winegrowing Leader Award.
Congratulations to all the Green Medal winners.
To kick off California’s Down to Earth Month, four wineries and vineyard companies were awarded 2026 California Green Medal Sustainable Winegrowing Leadership Awards, joining 11 years of past winners from throughout the Golden State. These awardees are recognized for their notable sustainability practices and innovation based on a comprehensive judging process focused on both sustainable viticulture and winemaking. Presented by several California wine organizations devoted to sustainability, four green medals are awarded annually in the following categories: Leader, Environment, Community and Business.
About the California Green Medal Sustainable Winegrowing Leadership Awards
The California Green Medal is presented by the California Sustainable Winegrowing Alliance, California Association of Winegrape Growers, Wine Institute, Lodi Winegrape Commission, Napa Valley Vintners, Napa Green, Sonoma County Winegrowers and Vineyard Team. California vineyards and wineries that participate in a sustainability program in California are eligible to apply in four award categories (Leader, Environment, Community and Business) that recognize outstanding achievement in sustainability. A judging panel of wine and sustainability experts make the final selections, and each recipient receives an engraved California Green Medal and is recognized for their contributions to California wines’ world-leading efforts on wine sustainability. A customized award ceremony also helps to share their achievement with staff, customers, media and other stakeholders of their choice.
