Howell Mountain
ハウエル・マウンテン
Napa's first sub-AVA, perched above the fog at 1,400–2,600 ft on volcanic soils, producing intensely structured, age-worthy Cabernet Sauvignon with deep color and firm, refined tannins.
Howell Mountain is a prestigious American Viticultural Area (AVA) located in the northeastern hills of Napa Valley, California. Established in December 1983 as the first sub-AVA within Napa Valley, the appellation sits entirely above 1,400 feet elevation—above the morning fog line—with some vineyards reaching 2,600 feet. The volcanic ash and iron-rich red clay soils are thin, dry, and nutrient-poor, forcing vines to produce small, concentrated grape clusters with thick skins. This high-altitude environment delivers longer sun exposure, cooler daytime temperatures, and wider diurnal swings than the valley floor, slowing ripening and building complexity. Howell Mountain is celebrated for powerfully structured, age-worthy Cabernet Sauvignon alongside noteworthy Zinfandel, Merlot, and Petite Sirah. Notable producers include Dunn Vineyards, La Jota Vineyard Co., CADE Estate, and Robert Craig.
Best for: Wine collectors and enthusiasts who appreciate bold, structured red wines with 20+ years of aging potential. Ideal for those seeking Napa's most powerful mountain-grown Cabernet Sauvignon, as well as old-vine Zinfandel and concentrated Merlot.

Frequently Asked Questions
- What makes Howell Mountain wines unique compared to other Napa AVAs?
- Howell Mountain sits entirely above 1,400 feet, above Napa's morning fog line. The combination of volcanic ash and red clay soils, higher UV exposure, cooler daytime temperatures, and large diurnal swings produces small, thick-skinned grapes with a higher skin-to-juice ratio. The result is deeply colored wines with intense tannins, concentrated fruit, and remarkable longevity—often out-structuring valley-floor Cabernets.
- How long can Howell Mountain Cabernet Sauvignon age?
- The best examples can age comfortably for 20–30 years or more. The firm tannin structure, high natural acidity from slow mountain ripening, and concentrated fruit give these wines exceptional cellar potential. Dunn Vineyards Howell Mountain Cabernet, for instance, is legendary for its 30+ year aging trajectory.
- What grape varieties are grown on Howell Mountain?
- Cabernet Sauvignon is the flagship variety and what the AVA is most famous for. Zinfandel has a long historical pedigree here—it was actually the grape that first brought Howell Mountain fame in the 1800s. Merlot, Petite Sirah, and Petit Verdot are also produced in smaller quantities, all showing the region's characteristic concentration and structure.
- Is Howell Mountain a good choice for wine beginners?
- Howell Mountain wines are bold and heavily structured, which can be intense for newcomers to red wine. They are best appreciated by those already comfortable with full-bodied, tannic reds like Napa Cabernet. That said, with proper food pairing—hearty grilled meats and aged cheeses—even beginners can enjoy their powerful character. Starting with a slightly older vintage (5+ years) makes the tannins more approachable.
- When was Howell Mountain AVA established?
- Howell Mountain AVA was officially established in December 1983, making it the first sub-appellation within the broader Napa Valley AVA. Its viticultural history, however, stretches back to the 1880s, when its wines won a bronze medal at the Paris World Competition in 1889.
