The 2,400-foot Sonoma Mountain range begins to rise above the town of Glen Ellen at the western edge of the Valley of the Moon. Found here are high-altitude, steep-sloped vineyards, with eastern exposures to catch the fog-free morning sun.
Powerful, yet elegant Cabernet Sauvignons grow here on unique red, volcanic, soil vineyards. The irregular folds and crevices of the mountain slopes also create microclimates suitable for limited production of a diverse range of other varieties, including Pinot Noir, Merlot and Zinfandel.
