Unlike the pending Calistoga AVA the Howell Mountain AVA not only exists but also was the first AVA to be carved out of the Napa Valley appellation, way back in 1984. Roughly centered around the town of Angwin and stretching north to south some 12 miles or so, it roughly parallels the range of the Diamond and Spring Mountain districts
This western facing AVA hugs the Vaca Mountain range that forms the eastern edge of the valley and benefits from the long hours of afternoon sun it receives. The great exposure of the vineyards is more important here than anywhere else in the valley as these rolling vineyards, concentrated between 1200 and 2200 feet above sea-level, are surprising cool, with daytime highs frequently 10 degrees lower than the valley floor. These lower temperatures lengthen the growing season and allow for valued hang time. The key to the wines here is the slowed down maturation cycle which allows the grapes to ripen in tune with the tannins, and yet retain naturally balanced acidity.

The name Howell Mountain gives a somewhat misleading impression for this area is really more of a high plateau as opposed to the vertiginous vineyards of Mount Veeder. As with the western mountain AVAs the soil here is volcanic in origin and offers excellent drainage, though the region is dotted with picturesque lakes. The area remains mostly wooded with only several hundred acres devoted to vines but the wines that are produced here are perhaps the most distinctive in the valley.
The terroir of Howell Mountain is quite assertive; these are lean and earthy wines if judged against most from Napa Valley. The soils here are very poor and the vines fight for their lives. The stresses the vines face and the well-drained soils yield small, intense grapes that translate into these distinctive wines, massively structured and speaking of the dirt from which they’ve come. This should not be mistaken for a lack of fruit however. These wines are well endowed with perfectly ripe fruit, and perfect balance. They just lack the jammy edge many wines from Napa exhibit and have replaced it with compelling layers of mineral and savory flavors.
Many grapes do very well in this mild climate, and while Cabernet remains the most prominent, brawny and powerful with deep fruit and imposing structure, it can be argued that the stars here really are the rich, spicy Zinfandels, the fully ripened, deep Cabernet Francs and the powerful, structured Merlots, as they tend to be the best one will find in the Valley.
