The deal expands Groundstar’s stewardship to over 320 acres
Press Release
Groundstar Vineyard & Estate, founded by Chiara Shannon and Joseph Brent, announces the acquisition of the historic Williams Ranch, a 247 acre property located at 7630 W. Highway 246 in the Sta. Rita Hills corridor. The transaction officially closed on February 13, 2026, marking a significant step forward in Groundstar’s long-term commitment to extend its regenerative land stewardship into a broader, integrated agricultural ecosystem.
Situated along one of Santa Barbara County’s most iconic agricultural corridors, the addition of Williams Ranch expands Groundstar’s stewardship to over 320 acres—a rare opportunity to implement regenerative farming at scale, prioritizing soil health, biodiversity, water resilience, and ecosystem vitality.
“This acquisition represents a large step forward for our work at Groundstar,” said Shannon. “Our focus is on farming in a way that supports the health of the land and, ultimately, the people and communities connected to it. With the Williams Ranch, we now have the opportunity to expand that work by integrating regenerative grazing, enhancing water systems, restoring native habitat, and supporting a more complete and resilient landscape.”
Expanding a Regenerative Framework
Groundstar’s approach is rooted in its regenerative organic farming principles, and is pursuing its Regenerative Organic Certified® (ROC) status. The Williams Ranch acquisition extends that commitment beyond the vineyard. Goals for the Williams Ranch include:
• Regenerative grazing to improve soil health, carbon sequestration, and ecosystem balance
• Water management strategies to support retention, biodiversity and drought resilience
• Wildlife conservation and habitat restoration, including native plant and ecological renewal
• Integrated agricultural systems aligning livestock, land, and long-term stewardship
The acquisition allows Groundstar to manage the vineyard and surrounding rangeland as one connected agricultural property, with vine cultivation, grazing, water retention, native habitat, and soil health practices supporting each other across the landscape.
A Legacy of Ranching and Local Connection
The acquisition carries personal and regional significance. The Shannon family brings decades of ranching experience, having operated a cattle ranch in the Texas Panhandle. The Williams Ranch creates an opportunity to carry that experience forward in Santa Barbara County.The property itself carries a deep-rooted local history. Long held by the Williams family, the ranch reflects the agricultural heritage of the Santa Ynez Valley and the Sta. Rita Hills corridor. Rodney Williams, from whom the property was acquired, is a well-known local rancher.
Chiara’s father, Mike Shannon—a Los Angeles native who helped lead the Shannon family’s former Texas cattle ranching operation and was pivotal to the transaction—is a member of the Rancheros, a historic group connected to the region’s ranching heritage. His involvement reflects a multi-generational ranching tradition that connects family history, regional relationships, and a shared commitment to responsible land stewardship.
“This project carries forward a family tradition of ranching, organic and regenerative agriculture, and care for the land” said Chiara Shannon.
Looking Ahead
Groundstar supports broader efforts to advance regenerative agriculture, including the MINDSET: Regeneration and Resilience Symposium, which brings together leaders across agriculture, science, and wine.
