Howell Mountain was the first sub-region of Napa to be recognized as a separate AVA way back in 1984. The region is known for complex, austere, and occasionally backwards age-worthy wines. The region overlooks St. Helena from the heights of the mountain range to the east and its 600-odd acres of vines are planted at elevations between 1,400 and 2,200 feet, or as the locals put it, "above the fog."

The history of wine production in Howell Mountain Wine Country began in the 1880s. The region is named after Isaac Howell, who settled in the area in 1847, and Howell Mountain wineries developed an early following during the 19th century. Several of these original “ghost wineries” have since been renovated.

The terrain of Howell Mountain is a mix of volcanic ash and clay soil on sloping hillsides. Because most of the region’s vineyards face west, the grapes are exposed to a lot of afternoon sun. These slopes are particularly valued for Cabernet Sauvignon.

A number of famous wineries produce equally famous (and pricey) wines from Howell Mountain fruit including Dunn Vineyards, Abreu, Hundred Acre, Turley, Lokoya, and Beringer. (Wine/Appellations)
