  • About
    Set along the western-most boundaries of Paso Robles, California, surrounded by the wild, and wide-open Santa Lucia Mountain Range of the Central Coast, Halter Ranch is a 2,700-acre nature estate dedicated to land, art, and legendary terroir-driven wine. Envisioned by Swiss entrepreneur, philanthropist, and world-leading land conservationist, Hansjörg Wyss, the estate is an homage to his mother, Alice, and a haven for the natural world to flourish and deliver exceptional, timeless wines.

    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, 10 acres of walnuts, and organically certified 17 acres of olives.

    Halter Ranch produces 100% estate-grown Rhône and Bordeaux-style wines. Primary wines produced are Grenache Blanc, Grenache-based Rosé, CDP (a Rhône style GSM), Syrah, Cabernet Sauvignon, and the flagship Estate Reserve, Ancestor.

    Winner of the Environment Award, California Green Medal: Sustainable Winegrowing Leadership Awards.
