Preston Farm & Winery is one of the most singular operations in Sonoma County: a working farm on West Dry Creek Road that produces olive oil, bread, eggs, and farm produce alongside Zinfandel and Rhône-focused wines. Its crops have been CCOF certified organic since 2002 and Demeter certified biodynamic since 2015, and the winery operates on an ethos of radical locality and self-sufficiency. The wines are honest and sometimes quirky, shaped by the farm's biodynamic rhythms rather than market trends. The tasting room is a destination experience: bread, olive oil, and bottles poured from the farm's daily production.
Old Vine Zinfandel, Dry Creek Valley: drawn from heritage Zinfandel that predates the Prestons' ownership; bright, balanced and built on moderate alcohol and good acidity.
Estate Syrah, Dry Creek Valley: a flagship Rhône red from the vineyard where Preston planted Sonoma County's first Syrah in the late 1970s.
Barbera, Dry Creek Valley: lively raspberry, lime and floral notes in a buoyant, food-friendly Italian style.
Carignane, Dry Creek Valley: a Prohibition-era heritage red, dark and rustic, honoring the valley's old field-blend tradition.
Sauvignon Blanc, Dry Creek Valley: a signature white, clean and herb-tinged with good acidity, first planted on a contract handshake with neighboring Dry Creek Vineyard.
Lou and Susan Preston have farmed here since 1973, converting an old prune orchard into a certified-organic polyculture farm of grapes, grain, olives and produce. Rhône whites Viognier and Roussanne also appear in the estate's Madam Preston white blend.
Preston has the most complete agricultural vision in Dry Creek Valley: Mediterranean-style wines (Zinfandel, Syrah, Grenache, Barbera, Carignane, Sauvignon Blanc, Vermentino, Roussanne) alongside vegetables, orchards, pasture, chickens, sheep, and a wood-fired bread oven. Private seated tastings run $35 per person for five or six estate wines, available by appointment daily for parties of six or fewer, in the farmhouse, on the front porch or at outdoor tables. Picnic tables under a pergola beside the bocce court can be reserved daily, and the farm store is open to walk-ins seven days a week. Friendly cats wander the property. The Prestons are as much farmers as winemakers, and a visit feels more like a trip to a working Mediterranean villa than a typical tasting room stop.
