Sonoma Mountain rises above the western edge of Sonoma Valley, a place of morning sun and afternoon shadow that produces wines of distinctive character and quiet authority. The mountain sits above the fog that fills the valley below, meaning vines here ripen under clear skies while remaining cooler than their elevation might suggest. Soils are volcanic and well-drained, ancient and complex. Cabernet Sauvignon grown here has a particular seriousness — structured, mineral, built for the long term. Benziger Family Winery, a biodynamic pioneer, and B. Wise Vineyards have helped define the mountain's modern identity.
Tasting fees are per person — $ under $25 · $$ $25–50 · $$$ $50–100 · $$$$ $100+. Reserve and seated experiences may run higher.

Cabernet was first planted at this east-facing Sonoma Mountain site in 1968. Founder Patrick Campbell, who bought the property in 1977, discovered he had inherited a unique clone now recognized by UC Davis as the Laurel Glen Clone. After 30 vintages, Bettina Sichel's group acquired the estate; certified organic since 2014, managed by Phil Coturri.
