High above Napa Valley, a mountain looms. Within its rugged terrain, one of California’s most iconic wine AVAs is crafting prestigious wines that rival those made miles below on the valley floor. Howell Mountain is elevated not only in altitude but also in prestige, celebrated especially for Cabernet Sauvignon. Beyond its peak, however, Howell Mountain holds a unique place in the history of the wine industry.
A Winemaking Past
Vines first took root here in the late 19th century when pioneers like Jean Adolph Brun and Jean V. Chaix recognized the promise of red clay and volcanic soils. In doing so, they founded Brun & Chaix Winery in the 1880s (today known as Ladera Vineyards) and quickly earned international recognition.
By the century’s close, more than 600 acres were under vine, and Howell Mountain wines were winning medals in Paris, St. Louis, and beyond. Soon, Charles Krug, Frederick Hess, and W.S. Keyes of Liparita and La Jota fame joined the ranks, further solidifying the region’s reputation for bold, age-worthy wines.
Above the Fog
Unlike many AVAs, Howell Mountain is defined not by rivers or property lines but by elevation. The boundary begins at 1,400 feet, placing the region “above the fog.” When the marine layer blankets the Napa Valley floor, Howell Mountain basks in sunlight, with cooler daytime highs and warmer nights. This unique climate slows ripening, allowing grapes to develop deep concentration and balanced acidity.
Meanwhile the soils here, nutrient-poor decomposed volcanic ash, known as tufa, and iron-rich red clay, force the vines to struggle. Notably resulting in yielding smaller berries and thicker skins. Which leads to wines with a firmer structure, inky color, and remarkable longevity.
AVA Status: A Pioneer in Its Own Right
In 1983, Howell Mountain became the very first sub-AVA established within the Napa Valley AVA. Which resulted in a designation that was groundbreaking, underscoring that Napa’s strength lies not only in its valley floor but in its mountainsides. Howell Mountain remains one of only five mountain AVAs in Napa Valley.
The Signature Style
It’s Cabernet Sauvignon reigns supreme, producing wines of dark fruit intensity, mocha and coffee undertones, earthy minerality, and tannic strength softened by a surprising elegance. Zinfandel, Merlot, Petite Verdot, Malbec, and Petite Sirah also thrive here, offering layers of expression across the appellation’s 1,500 planted acres. Aromas of blackberry, black cherry, currant, and plum often mingle with notes of tobacco, spice, and floral perfume, leaving a long, lingering finish that collectors treasure.
Modern Influence: A Cult Reputation
From the iconic Dunn Vineyards to Outpost, La Jota, Robert Craig, and Black Sears (the highest vineyard at 2,500 feet) today’s wineries continue the legacy of quality over quantity. With just 47 wineries and 38 growers across 14,000 acres, Howell Mountain has cultivated a cult reputation built on scarcity, authenticity, and the pursuit of excellence.
A Pinnacle of Napa Valley
Howell Mountain isn’t just a peak—it’s a pinnacle. Its volcanic soils, fog-free skies, and legacy of excellence have created a winegrowing sanctuary that remains unmatched. For collectors and oenophiles, wines from Howell Mountain aren’t simply bottles; they’re chapters of Napa’s living history.
