Napa One Block Challenge™ Field Day

A Napa One Block Challenge Field Day at Muir-Hanna Vineyards. Join us if you are already a participant of the One Block Challenge, or if you are a wine grower who is curious about regenerative viticulture.

The One Block Challenge™, developed by the Regenerative Viticulture Foundation and piloted in Paso Robles in February 2025, gives growers a low-risk, practical entry point into regenerative agriculture. Participants commit one vineyard block—or even a few rows—to trial selected regenerative practices for a single season. Each grower chooses from a regionally adapted menu that may include diverse cover crops, compost applications, removing herbicides, reducing tillage, and integrating livestock. Baseline and year-end soil assessments help participants understand the changes on their block and decide whether to expand these practices more widely.
