A typical summer day in the Gap begins with a distinctive, crisp coolness and a blanket of morning fog. By late morning the sun chases away the fog and temperatures rise. By mid-afternoon, however, the cooling maritime breezes begin, picking up speed as the afternoon progresses and bringing in fog almost every night. It is this cooling "wind tunnel" effect that distinguishes the Petaluma Gap from our neighboring winegrowing areas. The impact of the wind results in lower yields and grapes that reach physiological ripeness much later and at lower sugar levels while developing intense flavors with ideal levels of acidity.
The diversity of our wines comes from years of vineyard exploration, a careful understanding of the grapes, and respect to the essence of our fruit. Our sustainably certified vineyard incorporates practices derive from organics, permaculture, and biodynamics that we have learned over the years. From bee-keeping, owl and bat boxes to a carefully managed flock of over 200 sheep that graze and fertilize our land, to careful management of our pond system that ensures our water supply,
La Cruz Vineyard
The ancient sea-bed of the San Pablo Bay is mineral rich, clay soils that define this vineyard. Planted to chardonnay, pinot noir, syrah, viognier, and pinot gris, this is the heart of Keller Estate. Typical to this vineyard is a bright acidity and signature spice notes.
El Coro Vineyard
Sitting at the ridgetop of the Estate, this vineyard's loam soils are even more exposed to the wind that the La Cruz Vineyard. Planted exclusively to Pinot Noir, this jewel offers extraordinarily complex pinot noirs with delicate aromatics and structured tanins.
