The Halter Ranch / Hansjoerg Wyss Charitable Trust

The owner of Halter Ranch, Hansjörg Wyss, established the Halter Ranch / Hansjoerg Wyss Charitable Trust to ensure a strong future for the communities in which so many Halter Ranch employees live and work.

Investing in Our Community

Since its creation in 2021, the Halter Ranch/Hansjoerg Wyss Charitable Trust has granted over $1.7 million to support non-profits and educational programs, empowering the next generation of leaders in the local communities Halter Ranch calls home.

To ensure these resources make the deepest impact in the communities where our team lives and works, the Trust identifies partners through a proactive internal review.

Funding is provided by invitation only; we respectfully request no unsolicited proposals.

Halter Ranch

One Brand in Three Unique Destinations

Award-winning estate located in the Western hills of Paso Robles’ Adelaida District. Founded in 2000, the winery is dedicated to conservation, preserving 90% of its 2,700 acres as a permanent wild land. We specialize in high-quality Bordeaux and Rhône-style wines, including the flagship Ancestor and CDP blends, which reflect the unique limestone-rich terroir.

The original Paso Robles estate offers a picturesque visitor experience with unique amenities, including scenic tours, lodging, a private airstrip, and rides on the Halter Ranch Railroad.

Branching out beyond the Central Coast, Halter Ranch has expanded its winemaking and hospitality to two other well-known wine destinations - Temecula (Opened 2023) and Fredericksburg, Texas (Opened 2024).

Halter Ranch is a Paso Robles based Regenerative Organic Certified® winery and vineyard operation owned by Hansjörg Wyss. An man sitting on a large rock in a vineyard landscape during sunset, wearing a gray vest over a checkered shirt.
