Clos du Bois

Sonoma County wines across Chardonnay, Cabernet, and Petite Sirah blends.

Clos du Bois draws from the diverse terroirs of Sonoma County in California's North Coast, a region marked by cool coastal influences and varied microclimates that shape distinctive wines. The winery's portfolio centers on three flagship expressions: Coro Mendocino, a Petite Sirah–Merlot–Zinfandel blend that marries the structure of Petite Sirah with softer fruit notes; Calcaire Alexander Valley Chardonnay, sourced from one of Sonoma's premier white wine valleys; and Winemaker's Reserve Cabernet Sauvignon, built on the region's signature dark-fruit varietal. These wines have been assessed by Wine Enthusiast, Wine Advocate, and Wine Spectator, reflecting the winery's engagement with prestige critical evaluation. The range spans both red and white, anchored in classic California varietals and the specific growing conditions of Sonoma's distinct appellations.
