Unique in location, the vineyards at Keller Estate benefit from two very important maritime influences. The cool Pacific breezes that float off the San Pablo Bay from the south and those meandering through the Petaluma Gap bathe the vines in fog every morning, allowing longer hang time and even ripening.
Biochemist Ana Keller and Chemist Alex Holman share winemaking duties. Their vision each year is to allow the terrior to speak for itself with minimal intervention. They do this by caring for the vines and the soil through biodynamic and sustainable practices to preserve the land for generations to come. In the winery, Ana and Alex use a minimalist approach when considering modern winemaking technologies, and apply them only to refine the wine if needed.
