Keller Estate produces wines from Sonoma Coast, a region defined by cool maritime influence and fog-moderated growing seasons. The winery's portfolio centers on Pinot Noir, the signature varietal of this coastal territory, alongside Syrah—a grape that thrives in the region's temperate conditions. Precioso Pinot Noir and Rôtie represent the core offerings, with a Rosé of Pinot Noir rounding out the range. These wines have been evaluated by Wine Enthusiast, Decanter, Wine Advocate, and Falstaff. The maritime climate of Sonoma Coast favors wines with bright acidity and subtle fruit expression, characteristics that define cool-climate viticulture in Northern California's North Coast appellation.
