Russian River Valley
Long celebrated as the heartland of California Pinot Noir, the Russian River Valley is shaped by its signature coastal fog, which drifts inland from the Pacific and blankets the vineyards each morning. This daily interplay of cool mornings and warm afternoons slows ripening, allowing grapes to develop remarkable depth, structure, and purity – hallmarks of the wines we craft from this region.
For Kosta Browne, the Russian River Valley is more than a place. It’s our home and the heart of our story.
