About Stewart Cellars
Stewart Cellars is a dedicated estate winery in the Yountville sub-appellation in southern Napa Valley, producing wines that reflect the character of deep alluvial soils and significant Bay influence that moderates temperatures. Mike and Penny Stewart's design-forward Yountville estate — a striking modern building on Washington Street in the heart. The estate's commitment to quality viticulture and site-specific winemaking has earned Stewart Cellars a respected place among the region's most consistent and genuinely food-friendly producers.
The Yountville growing environment shapes everything Stewart Cellars produces. Deep alluvial soils and significant bay influence that moderates temperatures define the estate's vineyard character, contributing the structure, natural acidity, and terroir specificity that distinguish the finest wines from this appellation. Cabernet Sauvignon, Merlot, and Pinot Noir form the backbone of the portfolio, with each variety expressing a distinct facet of the estate's unique growing conditions. Winemaking at Stewart Cellars prioritizes transparency and balance over extraction, allowing the appellation's natural character to lead rather than winemaker intervention.
Visitors to Stewart Cellars 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 Yountville appellation. Whether visiting for a focused flight or a deeper exploration of the estate's vineyard programs, Stewart Cellars 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.
