About Us / Halter Ranch Vineyard History: In 2000, Swiss-born businessman Hansjörg Wyss fell in love with the Paso Robles area and purchased 900 acres of the original ranch, intent on producing the best grapes and wines possible from our ideally situated site. Fervently committed to quality, we have focused on developing our estate vineyard, renovating the historic barns and farmhouse, and designing a new state-of-the art winery. We are committed to the environment. In 2008 Halter Ranch earned the SIP Certification, (Sustainability in Practice) in all our farming and winemaking operations.
