While the beauty and history of the land are appealing, it is the richness of the soils that makes the hillside perfect for an estate winery. These soils are, in great measure, responsible for the dramatic intensity of the fruit associated with the ultra-premium wines produced at Robert Keenan Winery.
Keenan completed a solar power system on their property that went on-line in 2007. The system supplies all of the estate’s energy needs, including the winery, administrative offices, visitor hospitality area, and the homes located on the property. The Napa Valley Vintners have recognized Keenan as a “green” winery, which they proudly announce on the back labels: Solar Powered and Sustainably Farmed.

Above the town of St. Helena on the eastern slopes of the Mayacamas Mountains sits the Spring Mountain District.
A dynamic region, its vineyards, cut by numerous springs and streams, vary in elevation, slope and aspect. Soils differ throughout with over 20 distinct types inside of the 8,600 acres that define the appellation. Within that area, only about 1,000 are planted to vineyards. Predominantly farmed by small, independent producers, the region currently has just over 30 wineries.
During the growing season, late afternoon Pacific Ocean breezes reach the Spring Mountain vineyards, which sit at between 400 and 1,200 feet. Daytime temperatures during mid summer and early fall remain slightly cooler than those of the valley floor.
Spring Mountain soils—volcanic matter and sedimentary rock—create intense but balanced reds with lush and delicate tannins. The area excels with Bordeaux varieties such as Cabernet Sauvignon, Cabernet Franc and Merlot and in some cooler spots, Chardonnay.

Cabernet Franc, a proud parent of Cabernet Sauvignon, is the subtler and more delicate of the Cabernets. Today Cabernet Franc produces outstanding single varietal wines across the wine-producing world. Somm Secret—One of California's best-kept secrets is the Happy Canyon appellation of Santa Barbara. Here Cabernet Franc shines as a single varietal wine or in blends, expressing sumptuous fruit, savory aromas and polished tannins.
