Nicole Dooling and Michael Frey help operate Mariah Vineyards in the Mendocino Ridge alongside Nicole’s parents, Dan and Vicki. As founders, Dan and Vicki have mindfully tended their land for over 40 years, putting in the hard labor of planting and growing this vineyard from the ground up. Their family and vineyard have thrived due to their dedication, adaptability, and resourcefulness in working with nature. Situated at 2,400 ft elevation without irrigation, they holistically manage their vineyard using organic and regenerative farming practices.

In 2020, Mariah Vineyards partnered with the Savory Institute to pilot the Land to Market Ecological Outcome Verification program for vineyards worldwide. They are proud to be the first regenerative vineyard for Savory’s Global Land to Market Verified program and are dedicated to helping expand regenerative viticulture.

In this episode, John, Nicole, and Michael discuss:

  • How regenerative agriculture is a constant path of exploration and learning

  • Rewarding results coming from the process of trial and error

  • Different generations of growers working together

  • Cover crop management

  • Pruning for sap flow

  • Measuring and managing nutrient density
