At Provenance, we believe that the land is at the root of great wine. That’s why it’s so important we act as its steward at all times. Our Certified California Sustainable Winegrowing certification commits us to an annual assessment of 140 vineyard and 104 winery best practices using the California Code of Sustainable Winegrowing. Our Napa Green Land certification commits us to additional sustainability best practices. Both certifications require we prioritize, develop and implement action plans to continuously improve our sustainability.
Benefits of third party verified sustainable certifications:
Good for the Environment – Sustainable winegrowing preserves natural resources, improves air and water quality, and protects ecosystems and wildlife habitat.
Good for the Community – Sustainable winegrowing helps growers and vintners be stewards of both natural and human resources, preserving open space and providing scenic landscapes and contributing to their communities economically and culturally. Sustainability also helps provide a favorable environment for employees and neighbors.
