Vineyard Overview

In the shotgun of the Templeton Gap, the 127 acre ONX Estate Vineyard is home to complex soils, views of the historic Santa Rita Creek, and some of the most dynamic temperature swings in the Paso Robles AVA. The soils at ONX Estate are a complex mix of rocky alluviums. Large rocks mostly of calcareous sedimentary origin are scattered throughout the site. Sandy, gravelly loams define most of the property and provide excellent drainage for vine roots. The winemaking and vineyard teams strategically coordinated “micro blocks” to pair rootstock and grape varieties to the diverse soil, elevation and sun exposure. 57.2 acres are currently planted with 18 varieties. The singular site makes for a complex wine in your glass.
