Overview

ONX Estate is a 122-acre ranch property located in the Templeton Gap District AVA of Paso Robles, California. The Estate is nestled in a valley that was cut by the Santa Rita Creek, which defines the Southern border of the property. So far forty five acres of the estate have been planted with Grenache, Syrah, Mourvedre, Cabernet Sauvignon, Petite Sirah, Tempranillo, Zinfandel, Primitivo, Malbec, Petit Verdot, Viognier, Sauvignon Blanc and Grenache Blanc grapes.

Terroir

The soils at ONX Estate are a complex mix of rocky alluviums deposited upon the sloping terraces where the vines are planted.  Large rocks mostly of calcareous sedimentary origin are scattered throughout the site.  Sandy, gravelly loams define most of the property and provide an excellent medium for vine roots to proliferate. Few soils in the area are as unique, so in order to take advantage of this fact, we’ve planted a wide variety of small blocks - each with its own variety and rootstock matched to the intricate nature of its site.

The other equally important aspect of terroir is climate, and in that regard, we believe ONX Estate is located in a particularly special spot.  Our close proximity to the Pacific Ocean – nine miles as the crow flies – and situation in a low lying section of the Templeton Gap provides our Estate with natural “air conditioning” during the warm summer months.  During the growing season, as temperatures start creeping into the triple digits in much of Paso Robles, the hot air starts to raise skyward, which in turn pulls cool marine air in from the Pacific resulting in nighttime temperatures similar to those found along the coastline.  It is not uncommon for us to have temperature swings of fifty to sixty degrees between daytime high and nighttime low.  This combination provides an exemplary climate where the sun and heat ripen the crop and the cool air maintains a crisp level of natural acid in the berries.  All of these elements combine together to grow some delicious wine grapes.

History

The roots of the ONX Estate property go back to the Native Americans.  The Chumash and Salinan tribes seasonally migrated to Templeton to hunt and fish.  They termed the area “Ahjumawi” or “where the waters come together.” The Santa Rita creek (which now creates the Southern Border of the ONX property) flows to the Pacific Ocean during rainy seasons and would have provided excellent fishing.

1886 brought the founding of the city of Templeton.  The new city was the last stop on the Southern Pacific Railroad route.  From Templeton passengers took a stage coach to San Luis Obispo. The old stagecoach road ran along the Santa Rita Creek.
