Uncover the Secrets of a Property That Dates Back to the 1800s
Halter Ranch Estate, first established in 2000, sits on an expansive 2,700-acre estate with a rich history dating back to the 1800s. The property has had a total of six owners in that time, including current proprietor Hansjörg Wyss. First purchased by Edwin Smith in 1880 and then known as Smith Ranch, the property was used to raise Thoroughbreds, farm grain, and sell hogs. The Smith family also built the Victorian farmhouse, which, after careful restoration, still stands at the entrance to the property today. In 1943, the MacGillivray family took ownership and expanded the Ranch to include an airstrip and a hunting lodge. They encouraged both community members and travelers from across the country to visit by hosting large BBQs, political rallies, and opening the property for hunting. Fast forward to the year 2024, Halter Ranch, the organic vineyard and winery, continues to expand on what the founding family’s created while honoring the history that makes the estate so special and unique.

1880 Mr. & Mrs. Edwin Smith purchased the property to pursue agricultural interests and built the Victorian Farmhouse as their primary residence. The house burned down in 1885 due to a chimney fire but was rebuilt immediately after. The ranch consisted of approximately 2,000 acres of farm and pastureland.
1893 Miles of stone fencing were built on the Smith Ranch by Bernardo Mastagni, originally from Italy. However, due to the ranch being in debt, Smith never paid Mastagni for his services. The stone wall still sits near the current day Halter Ranch Delivery Truck Entrance.
1943 There were three owners whose names were undocumented between the end of the Smith’s ownership of the ranch in 1905 and 1943. In 1943, new owners, the John F. MacGillivray family, purchased the property for $56,000. Of the 1,640 acres, 1,000 acres were for pasturing cattle and 600 acres for grain production.
1960 Through the ‘60s and ‘70s, the MacGillivray family hosted barbecues, offered membership to their private hunting club on the property, and provided lodging to bring in additional income.
1967 The MacGillivray’s, with the help of neighbors, built a small airstrip on the property to accommodate guests traveling from various parts of the state. The community was often invited to the ranch to participate in short landing contests, flower sack bombings, and air shows. On any given day, there were about 15 planes on the ranch.
1970 Ronald Reagan flew to the ranch in his Aero Commander after being invited by the Paso Robles Republican Women’s Club for a barbecue event at the ranch. This event launched Ronald Reagan’s re-election campaign and drew in families from all over San Luis Obispo County.
1990 The movie “Arachnophobia” was filmed at the ranch, featuring the Victorian Farmhouse.
1992 John F. MacGillivray’s son, Fraser, published the book Adelaida which detailed the history of the area and its original settlers.
2000 Hansjörg Wyss purchased 900 acres from the MacGillivray's and named it Halter Ranch after his mother, Alice Halter. His vision was to transform the property into a vineyard and winery that would use methods of farming that were not harmful to the environment while still creating superior wine.
2003 The first vintage of the flagship Bordeaux-style reserve blend was created. It was made to showcase not only the finest grapes from the estate vineyard, but also Halter Ranch’s commitment to preserving history while looking to the future of the property. The Ancestor wine is an homage to the ancient Quercus Agrifolia, more commonly known as Coast Live Oak, sitting on the property.
2006 Since the inception of Halter Ranch in the year 2000, there have been two snowstorms. They both occurred on President’s Day weekend – once in 2006 & then again in 2009.
2007 In September of 2007, Halter Ranch hosted its first annual Ancestor Dinner in the Historic Barn. This dinner celebrated their flagship reserve Bordeaux-style blend, the Ancestor. Guests were even able to taste the first-ever vintage of Ancestor from 2003.

SIP Certified stands for “Sustainability in Practice,” which verified Halter Ranch had implemented sustainable vineyard and winemaking standards.
2009 The Covered Bridge was completed. The inspiration behind the construction was to transition from the historic to the contemporary portion of the property. Much of the modern architecture on the property was reminiscent of Wyss’ upbringing in Switzerland.
2011 The production facility was built with a mind toward ultimate efficiency, cleanliness, and quality. It was constructed into the hillside to utilize a gravity-flow system for fruit processing, reducing electricity consumption, and water use. The building functions to collect all water which goes to our reclamation ponds and used for irrigation.
2012 The caves in the production facility were built into the hillside. To regulate temperature, fans open when the temperature gets low enough outside and pulls air in, while a fan on the other end opens and pushes air out. A cycling fan helps circulate air throughout the rest of the cave. It was designed to hold approximately 2,290 barrels which equals ~55,000 cases of wine! Book a tour
