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.
Argot is the small-lot Sonoma Mountain specialist founded by self-taught winemaker Justin Harmon, who learned under 100-point Cabernet maker Russell Bevan before launching his label in 2007 with a single ton of Syrah. About 3,000 cases a year of Pinot, Chardonnay, Syrah, Cabernet, and Sauvignon Blanc — allocation only.
California's biodynamic pioneer — an 85-acre Sonoma Mountain ranch run as a self-sustaining ecosystem since the 1990s. Sheep graze between vines, ponds host beneficial insects, a half-acre insectary feeds the program. The Biodynamic Tractor Tram Tour winds through the estate and cave to a seated tasting with local cheese.
Harry 'Red' Coturri and sons Tony and Phil founded Coturri in 1979 on Sonoma Mountain above Glen Ellen, long before natural wine had a name. Tony has made zero-additive wine from organic, dry-farmed vines since 1964: native yeast, no sulfites, no filtration. He's the granddaddy of natural wine in California.
Hollywood actor Squire Fridell and his wife Suzy run GlenLyon as a mom-and-pop winery on a hillside between the Sonoma and Mayacamas ranges. Production stays under 1,000 cases of small-lot Syrah, plus a sparkling 'Lexy's Toast' and a port-style dessert wine. Tours are Scottish-themed and hosted by Squire himself.
Cabernet was first planted at this east-facing Sonoma Mountain site in 1968. Founder Patrick Campbell, who bought the property in 1977, discovered he'd inherited a unique clone now known as the Laurel Glen Clone. After 30 vintages, Bettina Sichel's group acquired the estate; organic since 2014, farmed by Phil Coturri.
