As Down to Earth Month begins, four of the state’s premier wineries were awarded California Green Medal Sustainable Winegrowing Leadership Awards, joining 32 past winners from throughout the Golden State. These awardees are recognized for their advanced 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, including the Lodi Winegrape Commission, four green medals are awarded annually in the following categories: Leader, Environment, Community, and Business.

Each recipient receives an engraved 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.

“It’s a pleasure to recognize the California wine community’s cutting-edge leaders in sustainability through the California Green Medal Awards,” said Allison Jordan, California Sustainable Winegrowing Alliance’s (CSWA) Executive Director. “Their stories illustrate the perfect synergy between growing exceptional winegrapes and crafting quality wines at different price points with an enduring commitment to resource conservation, environmental protection, and quality of life for their employees and community.” Winners of the 2023 California Green Medals are:
