SAN FRANCISCO — The eighth annual California Green Medal Sustainable Winegrowing Leadership Award winners were announced during Down to Earth Month, a celebration of California’s sustainable viticulture and winemaking. Presented by several California wine organizations devoted to sustainability, four Green Medals have been presented in the following categories: Leader, Environment, Community, and Business.

“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 premier wines with an enduring commitment to resource conservation, environmental protection, and quality of life enrichment for their employees and community.”

Winners of the 2022 California Green Medals are:

They also have two all-electric Monarch tractors and use lightweight glass bottles to reduce their carbon footprint. Read more
