Founded by Robert Mueller in the Russian River Valley in the late 1970s, Mueller Winery built its reputation on classically styled Pinot Noir and Chardonnay sourced from some of Sonoma County’s most coveted cool-climate vineyard sites. The winery’s focus has long been on restrained, site-driven wines that emphasize balance and transparency over sheer ripeness, reflecting the influence of the fog-laden conditions that define the region. The “Cuvée X” bottling represents a more limited and carefully selected expression of Russian River Valley Pinot Noir, drawn from vineyards whose Goldridge soils and maritime climate provide the tension and aromatic lift that have made the appellation one of California’s benchmark Pinot Noir terroirs.
