About Us

The Sonoma Mountain to the west of the B.R. Cohn estate acts as a buffer to the coastal fog. We also benefit from the continual air movement created by the narrowing of the valley between Sonoma Mountain and the Mayacamas Mountain Range at our location. These climatic factors, combined with our vineyards being situated over hot springs, result in an earlier bud break and extended growing season for our fruit. Our grapes develop full tannins and flavor profiles every year, even in the most challenging vintages.

"Olive Hill Estate Vineyard is blessed by natural underground hot springs that warm the soil, creating a naturally frost-free environment throughout the growing season."


Olive Grove

Olive Hill Estate is named after our grove of over 450 Picholine Olive Trees dating back to the mid-1800’s.

(Italian word from piccolo – meaning small, petite)

Our winemaking philosophy is to produce wines that are true expressions of the land and vineyards we farm, offering our customers delicious representations of each grape varietal.
