Our Vineyard


"With an inspiring piece of land that allows the varietal to flourish and thrive.  Some soils are ideal for Cabernet while others are better suited for white wines.  QTR Estate is on a rocky hillside made up of old volcanic material making it the perfect environment for growing Cabernet.”
  Jim Barbour, Viticulturist

The land of QTR Estate was formed during the last 1.6 million years and sits on an un-named and inactive fault. The western portion of the fault is underlain by Pliocene-age sedimentary deposits which are sandy, silty, and made up of volcanic gravel. The eastern portion of our site is made up of older Jurassic and Cretaceous-age sedimentary, igneous and metamorphic rocks of the Francisco Assemblage. At some point in its history, there was a deep bedrock landslide creating debris that is now our top and subsurface soils. This debris is largely composed of disrupted claystone bedrock with cobbles and boulders of volcanic matter up to 24” in diameter.

Our site is located on the lower elevations of Howell Mountain spanning 850 to 1200 feet and benefits from afternoon sun exposure and cool evening breezes. The vineyard is divided into 7 vineyard blocks ranging from one-third to nearly 2 acres in size. In total, just over 6 acres are planted. Four clones of Cabernet Sauvignon and Chappellet Chenin Blanc budwood were selected specifically for its soils. The vineyard is harvested according to these small blocks and vinified separately. When blended, the varying flavors create the complex wines of QTR Estate.  

QTR Estate is sustainably farmed and maintained to ensure it will endure for generations.
