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 2000-acres, with 281-acres of SIP (Sustainability in Practice) Certified wine grapes, 15-acres of walnuts, and 10-acres of olives.

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 281-acres. Sixteen 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 18% of Halter Ranch is dedicated to farming and structures; the rest is left to natural landscape, mainly oak woodland and wildlife corridors.

SIP Certification

In 2008 Halter Ranch achieved SIP certification, a rigorous, third-party review which validates the winery and vineyard’s commitment to sustainable practices. When you find the SIP seal on our bottle you can be assured we are preserving and protecting the natural environment, treating our employees and community with care and have sound business practices with a long term view that protects both the present and the future.
