Halter Ranch is located in Paso Robles on California’s Central Coast. It is protected from the ocean by the Santa Lucia Mountain Range. Halter Ranch has a rich history combined with a commitment to quality, science-driven sustainable methods, and environmental stewardship.

Hansjörg Wyss purchased the original property in 2000, renovated the 19th century Victorian farmhouse and enlarged the vineyard. The estate spans over 2,700-acres, with 200-acres of sustainably produced wine grapes, 15-acres of walnuts, and 17-acres of organically certified olives.

Wildlife Conservation

Halter Ranch spans 2,700 acres, with 90% of that left to wildlife conservation. Our commitment to sustainable wine growing compliments our obligation to the pristine biodiversity of the westside of Paso Robles. The ancient oak trees, wild manzanita, and fragrant sagebrush make up the California Chapparal that is home to a myriad of wildlife such as mountain lions, Tule elk, coyotes, and deer to name a few.   

Our Winery

In 2011, Halter Ranch completed a new production facility utilizing a multi-level gravity flow system. Gravity flow allows the winemaker to handle the fruit in the gentlest way possible, by preventing the pumping of stems and seeds. The winery’s night air-cooling, natural lighting, and 20,000 square feet of caves are integral to its energy efficiency and sustainability. Cool mass provided by the limestone in the hillside, along with concrete in the walls of the cave, stabilizes the temperature at 56° while maintaining ideal humidity for wine storage.

Our Vineyards

The estate vineyard was initiated in 1996 and has since been expanded to its present 200-acres. Twenty grape varietals at Halter Ranch occupy the steepest, most south-facing slopes on the property, which reach an elevation of 1,950 feet and provide excellent sun exposure. The emphasis on quality in the vineyard is complemented by a commitment to environmentally responsible grape-growing practices. Planting on only a small portion of the property’s acreage preserves a diverse environment, mitigating the effects of a monoculture. Only 200 acres of Halter Ranch's 2,700 acres are dedicated to farming and structures; the rest is left to natural landscape, mainly oak woodland and wildlife corridors.
