Switchback Ridge Wines are sourced exclusively from the Peterson Family Vineyard in Calistoga. The property has been in the Peterson family since 1914 and encompasses nearly 100 acres located at the mouth of Dutch Henry Canyon. For over 75 years the property was primarily maintained as a farm and plum orchard, with vines intermingled amongst the trees. In 1990, the orchards were replanted to vineyard, where there are currently 18 acres of Cabernet Sauvignon, Merlot and Petite Sirah vines, in addition to a three acre 50+ year old Petite Sirah block that John Peterson helped plant as a child.
