Unearthing the Spring Mountain District

Located at a low point of the Mayacamas Mountain range on Napa Valley's western hillside lies the appellation known as the Spring Mountain District. Covering 8,600 acres, there you will find 1,000 acres planted to vineyards – 100 of those belonging to our family. The Spring Mountain District received its official designation as an American Viticultural Area (AVA) in 1993. 

The Climate, Terroir, and Soil

The terroir of Spring Mountain is defined by diverse topography, climate, and soils. It's a cooler and wetter appellation compared to the valley floor, and most vineyards sit above the fog line, providing warmer nights and cooler days. The marine layers from San Pablo Bay and the Pacific Coast affect mid-summer and early autumn temperatures. Spring Mountain's mean temperatures during the ripening months, September and October, are considered ideal for most wine grape varieties.

Spring Mountain's terroir depth varies and tends to be deeper than other nearby mountain terrains. The soils contain an equal mixture of sedimentary rocks (sandstone and conglomerates) and Sonoma volcanic formations. This allows the region to distinguish itself from the adjacent mountain areas and create a unique environment for captivating and complex wines.

The Wines

About 90% of the wine produced in Spring Mountain is red, predominantly Cabernet Sauvignon.
