Join RVF for a post-harvest Napa One Block Challenge™ Field Day at Opus One. Focused on animal integration, this field day is open to anyone interested in learning more about regenerative viticulture, whether or not you currently incorporate animals into your farming practices.
Opus One team members, Assistant Winemaker / Agroecologist Kimberlee Marinelli and Sustainability Specialist Haley Nagy, will share their grazing journey, highlighting key insights, lessons learned, and the results of side-by-side regenerative trial blocks that attendees will have the opportunity to experience firsthand.
Tommy Fenster, Ph.D of UCDavis and The Ecdysis Foundation will present highlights of his recently published 2026 study of grazing in vineyards. Bring your own stories, questions, and open minds for an inspiring day of peer learning.
One Block Challenge™ Field Days are open to all wine growers eager to learn and share knowledge about regenerative farming from peers and invited experts.
