About Dunn Vineyards
Dunn Vineyards is a dedicated estate winery in the rugged, high-elevation Howell Mountain appellation above the Napa Valley fog, producing wines that reflect the character of volcanic, iron-rich soils and cool elevations that extend the growing season. Randy Dunn’s 1979 Howell Mountain cult Cabernet estate — the winemaker who built Caymus Vineyards’ reputation before est. The estate's commitment to quality viticulture and site-specific winemaking has earned Dunn Vineyards a respected place among the region's most consistent and genuinely food-friendly producers.
The Howell Mountain growing environment shapes everything Dunn Vineyards produces. Volcanic, iron-rich soils and cool elevations that extend the growing season define the estate's vineyard character, contributing the structure, natural acidity, and terroir specificity that distinguish the finest wines from this appellation. Cabernet Sauvignon, Zinfandel, and Merlot form the backbone of the portfolio, with each variety expressing a distinct facet of the estate's unique growing conditions. Winemaking at Dunn Vineyards prioritizes transparency and balance over extraction, allowing the appellation's natural character to lead rather than winemaker intervention.
Visitors to Dunn Vineyards can expect a genuine and unhurried tasting experience that reflects the estate's commitment to quality and hospitality. The tasting room provides an authentic introduction to the estate wines and the Howell Mountain appellation. Whether visiting for a focused flight or a deeper exploration of the estate's vineyard programs, Dunn Vineyards offers the kind of direct producer experience that wine tourism in California wine country is built on — knowledgeable, welcoming, and genuinely connected to the land and the wines it produces.
