Howell Mountain
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.
