Atlas Peak

Atlas Peak, including the Soda Canyon and Foss Valley subregions, encompasses the western slopes of the Vaca mountains on the southern end of Napa Valley. A summit of nearly 2,700 feet provides plenty of clearance above the cool morning fog, so vineyards here enjoy more sunlight, warmer days, and cooler nights. However, the nearby San Pablo Bay to the south generates an inversion layer of cool air trapped beneath the warmer air above, offering a reprieve from the temperature extremes characteristic of the other high-elevation appellations. Overall, the growing season is one of moderate temperatures and high UV exposure, resulting in complex fruit with advanced phenolic development.
