info_outlineIn 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
