This Regenerative Vineyard is Redefining Terroir
#12 – Michael Frey is the co-founder of DIRT Wine and second-generation steward of Mariah Vineyards, the first vineyard in the world to be Ecological Outcome Verified and produce Land to Market Verified wines. Located on a remote ridge 2,400 feet above sea level in Mendocino County, California, Michael and his wife Nicole have transformed her family’s vineyard into a thriving model of regenerative viticulture—farming without irrigation or synthetic chemicals, integrating livestock via Holistic Management, and using real ecological monitoring to drive land management decisions.
In this episode, we explore:
– how Michael and Nicole convinced the older generation to embrace a new regenerative path
– the specific vineyard practices they’ve adopted—from diverse cover crops and contract grazing to sap analysis and pollinator trials
– the disconnect between terroir and soil health in mainstream wine culture
– and why transparency, not just flavor, might be the most radical thing you can put on a wine label.
We also dig into the challenges of regenerative farming in a dry-farmed vineyard at elevation, the aesthetic tensions between “clean” and “complex” landscapes, and how Michael is thinking about measuring nutrient density and flavor outcomes at a deeper level.
