The Mountain Winery is a concert and event venue in unincorporated Saratoga, located at the site of the former Paul Masson winery. On June 25, 2018 Mt. Winery applied to modify their previously approved July 2006 Architectural and Site Approval to complete the improvements authorized by that 2006 ASA. These improvements included a wine tasting room, winery plaza building, plaza deck building, office and storage facility, box Office, and garden terrace. This development proposed approximately 42,000 square feet within the boundaries and limits of the original 2006 ASA modification and the current approved Use Permit for the property. On October 4, 2018, the County of Santa Clara approved Mt. Winery’s proposed ASA modification.
