• 080: Transitioning from Grape Grower to Winemaker with Jim Duane - Part 1

  Many vineyard owners eventually consider moving beyond grape growing into winemaking, whether to create a new revenue stream, take control of their fruit, or explore a more creative outlet. In this episode, we welcome winemaker and podcaster Jim Duane of Seavey Vineyard and the Inside Winemaking podcast for the first part of a two-part discussion on how growers can make this transition successfully. The conversation discusses the mindset, skills, and resources needed to move from vineyard to cellar. Jim shares why a formal chemistry degree isn’t required to produce quality wine, how growers can build confidence in their palate, and which common flaws are most important to recognize early. He also outlines three stages of winemaking where growers need to focus their attention: harvest chemistry, fermentation management, and post-fermentation protection. Listeners will also gain insight into the required equipment for red and white winemaking, the importance of temperature control at each stage, and why barrels can be a turning point for quality. Fritz and Jim round out the discussion with advice on navigating licensing, compliance, and regulatory hurdles, plus a look at custom crush facilities as an option for growers who want to test the waters without a full winery investment. This episode delivers practical, confidence-building advice for any grower curious about making wine and lays the foundation for part two, where the focus shifts to how vineyard practices change once you’re also the winemaker. In this episode, you will hear: Why a chemistry degree isn’t necessary to make quality wine Three key stages of winemaking where growers must focus their attention The most common wine flaws every new winemaker should learn to detect Equipment essentials for red and white winemaking at a small scale How custom crush operations can help growers test the waters before fully committing Follow and Review: If you enjoyed this episode, be sure to follow the podcast and leave a 5-star review on Apple Podcasts!

• 078: Beyond Organic Wine with Adam Huss

  In this episode of Vineyard Underground, Fritz welcomes Adam Huss — host of the Beyond Organic Wine podcast, winemaker at Centralas Wine, and creator of the Crenshaw Cru Wine Garden in South Los Angeles. Adam shares his unconventional path into winemaking, beginning with a career in the nonprofit sector before launching a winery focused on ecological and community-driven practices. The conversation explores Adam’s philosophy of going “beyond organic” to embrace an ecological approach to winegrowing — one that avoids getting boxed into industry buzzwords and instead focuses on the interconnectedness of soil, plants, people, and place. He discusses his work with regenerative agriculture pioneer Kelly Mulville at Paicines Ranch, his shift toward sourcing local fruit (including prickly pears and other native plants), and his experimentation with vitiforestry — a centuries-old practice of integrating grapevines with trees to create resilient, biodiverse systems. Adam also explains how transparency in winemaking, creative use of wild or locally abundant ingredients, and community involvement shape his vision for wine that is both place-specific and environmentally sound. Listeners will hear stories from his LA-based wine garden, lessons from crop failures, and his plans for a vitiforestry project in New York that could produce wines unlike anything on the market. Whether you grow grapes conventionally, organically, or somewhere in between, Adam’s journey offers a fresh perspective on how to balance environmental stewardship, economic sustainability, and community engagement in vineyard operations. In this episode, you will hear: How “beyond organic” focuses on ecological connections rather than labels Lessons from Paicines Ranch on listening to the land before planting The concept and practice of vitiforestry, from hedgerows to “married vines” Creative use of local and wild ingredients in winemaking The role of community in sustainable agriculture and wine culture Follow and Review: If you enjoyed this episode, be sure to follow the podcast and leave a 5-star review on Apple Podcasts!

• 077: Transitioning Vineyards to Regenerative Organic Certification with Hilary Graves

  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 Follow and Review: If you enjoyed this episode, be sure to follow the podcast and leave a 5-star review on Apple Podcasts!
