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. 67 acres are currently planted with 14 varieties. The singular site makes for a complex wine in your glass.

Vineyard Tour Experience

Touring the vineyard at the ONX Estate is all about discovery, delicious wine, and education. You are invited to sink your boots into authentic wine country soil and immerse all five senses while visiting our estate. The hour-long tour experience begins in the Tractor Shed, an outdoor covered patio where you can wander out back for tranquil views of the Santa Rita Creek. From there your knowledgeable tour guide will drive you around the vineyard in an off-road vehicle. As you travel through the vines and over the hills your friendly guide will give you an overview of seasonal developments in the vineyard. You’ll taste our wine right where the grapes were grown.  Along the journey you’ll stop at our “Oases”. These serene hideaways offer respite from the busy world beyond the vineyard. Tours are available year round. Each season at the vineyard provides its own unique opportunity to learn about the land and the wine growing process.

Tours can accommodate up to 6 people. Walking tours are available for larger groups and groups that prefer not to go "off-road". Sign up below.
