Napa’s Nested AVAs : Howell Mountain
"The terrain of Howell Mountain is often steep hillsides with vineyards nestled between forests of pine, fir and oak trees. When the valley floor is covered in a blanket of fog, Howell Mountain is above the fogline, taking in the sunshine. The resulting wines, specifically Cabernet Sauvignon, are intensely structured, filled with great red fruit flavors and can age beautifully in a bottle for 20+ years."

Howell Mountain and the Howell Mountain AVA are named after the Isacc Howell family, early settlers who moved to the area in 1846. In 1877, two of the area's first winemakers, Jean Adolph Brun (pictured left) and Jean V. Chaix planted 20 acres of grapevines from seven varieties which were sourced from Medoc in Bordeaux. They were among the first to operate successful vineyards in the area during the wine boom of the 1880's. They founded Nouveau Medoc Cellar and later Howell Mountain Winery in 1886, which was one of the most expensive construction projects in Napa at the time. Other early Howell Mountain winemakers included Charles Krug, J. Thomas and George McMee.
Howell Mountain first made history as a recognized wine producing region in 1889 when winemakers Brun and Chaix won a bronze medal at the Paris World Competition. However, with the outbreak of Phylloxera in the 1890's and Prohibition in the 1920's, winemaking in the area came to a standstill. All the wineries in the region closed and vineyards were either abandoned or replanted with different crops. It was not until the 1960's when interest in winemaking returned to Howell Mountain. The region was officially designated an American Viticultural Area in 1983 and was the first sub-appellation of the larger Napa Valley AVA. It is also the first mountainous nested appellation to be established, with the southern boundary of the AVA beginning at 1400 feet above sea level.
Overlooking the town of Saint Helena, CA, Howell Mountain AVA is a sub-appellation of the Napa Valley AVA and is located in the northeast side of Napa Valley near the town of Angwin. Howell Mountain AVA was established as an American Viticultural Area in 1983 and was the first sub-appellation within the greater Napa Valley AVA. Prior to Prohibition in the United States, the region was widely known for its Zinfandel but in the mid to late 20th century Cabernet Sauvignon became the dominant grape variety.
Howell Mountain was the first mountainous nested appellation to be drawn and declared. It is also unique in that, unlike the other mountains which run down to connect with the valley floor appellations, the AVA’s southern boundary is 1,400 feet (427m) above sea level. This boundary was selected by the AVA’s founders because that was the elevation at which the fog crested. The thinking was that vines grown above this elevation would be dramatically distinct from those grown beneath.
