Wild Horse Valley

Looking for a hidden gem? With only 100 acres of vines planted and having the coolest climate in all of Napa, Wild Horse Valley is the perfect place for growing Pinot Noir and Chardonnay.


This wild area has most of its area dedicated to nature reserves and other types of farming, however, there are a few vineyards planted on quartz and granite soils, which makes this place unique.

Wild Horse Valley wines to know

With such a small amount of acres under vine, there are few varieties here. But the combination of the cooling influence of San Pablo Bay and elevation of 1200-1400 ft. make Wild Horse Valley the coolest AVA in Napa, even cooler than Los Carneros - the perfect place for Pinot Noir and Chardonnay.

The quartz and granite soils, paired with the cooling influences, creates wines with an intense mineral expression, and high levels of fresh acidity.

Whilst there are very few wineries in this region, the fruit is so highly prized that it is often used as an important blending component in other Napa Valley wines.

The picturesque Kenzo Estate is just north of the official boundary of Wild Horse Valley.

Wild Horse Valley AVA Terroir

This relatively unknown gem of a valley is super cool, in both senses of the word. It has a unique combination of cooling breezes blowing in from the cold bay and elevations of 1200 - 1400 ft. It’s nestled in the Vaca Mountains which give it its elevation. This combination means that the diurnal shift can be extreme, leading to floral aromas in the wines and the retention of high levels of acidity - the result is fresh, complex, ageworthy Pinot Noir and Chardonnay.
