In this episode, we welcome Hilary Graves, Vineyard and Grower Relations Manager at Booker Wines, to discuss how she successfully transitioned an Organic vineyard to regenerative organic certification. With over 20 years of field experience on California’s Central Coast, Hilary brings practical strategies and candid stories about what it really takes to move beyond standard organic practices.
Hilary explains the core pillars of regenerative organic certification — soil health, social fairness, and animal welfare — and why she and the team at Booker Wines chose to pursue this path. She walks listeners through how integrating multi-species cover crops, implementing low-till and no-till practices, and bringing in grazing livestock have helped improve soil structure, increase water retention, and reduce reliance on inputs. Fritz and Hilary also dig into the challenges of vineyard mechanization on steep terrain, minimizing tractor passes, and creative pest control strategies, including releasing predatory lacewings by drone to combat leafhoppers.
Whether you’re already farming organically or just exploring what’s next, this episode offers tangible examples of how even small changes can drive long-term benefits for your soil, your business, and the environment.
In this episode, you will hear:
The difference between organic and regenerative organic certification
How to build a diverse cover crop blend (and why 15 species might be better than five)
Using a Yeomans plow to increase water infiltration without disturbing soil structure
Grazing sheep for cover crop termination in a mutually beneficial partnership
Why releasing beneficial insects by drone can outpace traditional sprays for pest control
