Napa County Soil Series

Guenoc-Rock outcrop complex.

Soil characteristics

This area, which predominantly covers the southeast part of the vineyard, is characterized by deep red/yellow/pink clay loam with less rock than other areas on the vineyard.  It was originally planted in 1870 by German settlers due to its somewhat less rocky soil.

Topography

The crew refers to many of these blocks as “Las Olas,” or "The Waves,” to describe the undulating landscape.  The rolling, south-facing hills give warmer exposures to Cabernet Sauvignon, Merlot, and Syrah, while Malbec and Merlot thrive on the northern facing hills.

Climate

This area’s name and climate reflects its similarities to the Bordeaux region of France. Overall, the temperatures are cooler in this part of the vineyard than in the other regions. The proximity to Rector Canyon pulls in cool marine air in from Napa Valley on foggy nights and collects cool air draining out of Foss Valley on clear nights.

Resulting fruit

These exposures and temperatures contribute to the delicate acid and sugar accumulation of these grapes, resulting in complex, elegant wines.
