Geography & Climate

Napa Valley is a small, narrow valley about 30 miles long and a few miles wide. It is flanked by the Vaca Mountains to the east and the Mayacamas Mountains to the west. This geography creates a perfect climate for grape growing, with a variety of microclimates.

The San Pablo Bay at the southern end funnels in cool fog and breezes, making the southern part of the valley (like the Carneros AVA) cooler and ideal for Chardonnay and Pinot Noir. As you move north, the climate gets progressively warmer, providing the perfect conditions for ripening Cabernet Sauvignon.

The valley floor and the surrounding hillsides offer a complex mosaic of soil types, contributing to the diversity of wine styles.
