Experience the flavor of old California at this historic west side ranch. Our steep hillside vineyards, limestone-rich soils and sustainable farming practices enable us to produce 100% estate-grown wines of the highest quality, showcasing Bordeaux and Rhone Valley wines.

Halter Ranch dates to the 1880s, when it was part of a 3,000-acre property owned by Paso Robles pioneer Edwin Smith. The beautiful Victorian farmhouse Smith built on the ranch in 1885 remains a west side Paso Robles landmark.

In 2000, Hansjoerg Wyss, a Swiss-born businessman, purchased 1000 acres of the ranch, convinced Paso Robles has the potential to produce wines rivaling the finest from California and the world.

Fervently committed to quality, we have been busy developing Halter Ranch’s 280-acre vineyard, and crafting estate wines, renovating the historic buildings, and building a new, state-of-the-art winery and wine cave.

Halter Ranch Vineyard boasts 13 different grape varieties – primarily Bordeaux and Rhone-styles. The vines are planted on steep, south-facing slopes reaching 1,600 feet in elevation and boasting soils rich in limestone, a feature of many of the world’s finest vineyards. High-density plantings, multiple clones and root stocks, and low yields enable us to produce fruit of superb quality. Committed to environmentally responsible grape growing, the vineyard is farmed sustainably, earning the SIP (Sustainability in Practice) Certification.

Halter Ranch wines, Cabernet Sauvignon, Syrah, CDP (red Rhône blend), Rosé, Grenache Blanc and our estate reserve Bordeaux blend named Ancestor are hand crafted by our winemaker, Kevin Sass. Our mission is to transform the superb fruit from our estate vineyard into richly flavored wines with bright acidity and a refreshing vein of minerality, wines that are fully evocative of their variety and place.
