Why This Region Matters
Howell Mountain was Napa's first sub-AVA, and it remains one of its most distinctive. Rising above the fog line on the eastern Vaca range, these high-elevation vineyards bask in sunshine while the valley floor below sits under morning fog. The result is intensely structured, tannic, age-worthy Cabernet with mountain-grown concentration and a signature firmness.

Distinctive Climate
At 1,400 to 2,200 feet, Howell Mountain sits above the fog line, so the vines see more even sunshine and less daily temperature swing than the valley floor.

42 producers in Howell Mountain are catalogued on WinoNotion, from boutique family estates to established names.
Part of Napa Valley
Howell Mountain is a distinct sub-region within Napa Valley, with its own character worth seeking out on any visit.
Climate & Terroir
At 1,400 to 2,200 feet, Howell Mountain sits above the fog line, so the vines see more even sunshine and less daily temperature swing than the valley floor. Volcanic ash and red iron-rich soils stress the vines, yielding small, concentrated berries with formidable tannic structure.
Visiting Howell Mountain
Howell Mountain is remote and forested, centered loosely on the hamlet of Angwin. The town of St. Helena lies down the mountain to the west.
