Napa Valley Wine Regions

Napa Valley certainly enjoys a rich wine history. In 1981, Napa Valley became the first American Viticultural Area (AVA) in California and the second in the United States. Since its inception, the valley has expanded to include 16 minor AVAs inside the Napa Valley AVA. [2] The region encompasses diverse soils and weather that allow various grapes to flourish. The region’s exceptional soil has made it the wine capital of the United States. Getting to know the unique areas of Napa lends a holistic perspective of the origin of some of the finest wines produced in California, and maybe the whole United States.

Sub-Regions

Los Carneros AVA

The Los Carneros AVA was founded in 1983 and is likely the coldest of Napa Valley’s AVAs. It is situated in the most southern portion of the valley, close to chilly winds and frequent fog, which allows for the cultivation of cool-climate varietals. This consists of both Pinot Noir and Chardonnay. This AVA is the pioneer of Pinot Noir in Napa Valley, with 9,000 acres of planted vines. Pinot Noir, Merlot, and Chardonnay are its primary grapes.

Howell Mountain AVA

Howell Mountain American Viticultural Area (AVA) was established on December 30, 1983, making it one of Napa Valley’s first AVAs. The average altitude of the AVA is between 1,400 and 2,600 feet. Thus, the area enjoys abundant sunshine due to its location above the fog line. Cabernet Sauvignon, Merlot, and Zinfandel are the primary grapes grown in this area. The AVA’s Zinfandel wine was especially well-liked prior to the Prohibition era. The appellation’s 600 acres of grapes are situated on volcanic soils.

Wild Horse Valley AVA

The Wild Horse Valley AVA is adjacent to San Pablo Bay, making it susceptible to fog and wind. The altitude is between 850 and 2100 feet above sea level. The AVA was established on November 30, 1988, and comprises two separate regions: the western section is fairly high and is affected by fog and wind from the bay area. The eastern portion is shielded by hills, making it warmer than the western portion.

Stags Leap District AVA

This appellation was established on January 27, 1989, and it is home to some of the oldest wineries in all of California.[3] The Fay Vineyard, located inside the region, supplied the grapes for the winning wine at the 1976 Judgement of Paris blind wine tasting competition. Not only does it have the distinction of being the first appellation to be designated for its unique soils, but it also has a unique history. Volcanic and river sediment soils predominate in the Stags Leap District American Viticultural Area. This little appellation consists of about 2,700 acres, about half of used for vineyards. Cabernet Sauvignon is the primary varietal grown in this area.

Mt. Veeder AVA

The Mayacamas Mountains are the home of the Mt. Veeder American Viticultural Area (AVA), which was designated on February 20, 1990. There are one thousand grape acres in the AVA, located between 500 and 2,600 feet above sea level. Because of its unique terroir, the wine produced there has a distinctive “briary” flavor. The height is high enough to keep most vineyards out of the fog, and the temperatures range from chilly to mild. As a consequence, it experiences more extreme diurnal temperature swings than other AVAs in the valley. Some of the most popular grapes include Cabernet Sauvignon, Merlot, Zinfandel, and Chardonnay.

This Day in History

March 1, 1825 – On this day, Charles Krug was born in Prussia. Krug moved to the United States in 1847 and was hired as the first commercial winemaker in Napa Valley. He established the first winery in Napa Valley in 1861, the Charles Krug winery, and is often referred to as the father of wine in the region. Krug also introduced the cider press as an efficient way of winemaking. Krug’s influence sparked the growth of the winemaking industry across Napa. By 1889, there were more than 140 wineries in Napa Valley thanks to Krug.

April 18, 1906 – On this day, a catastrophic 7.8 magnitude hit San Fransisco Bay and the surrounding areas, causing structural damage to many wineries.[5] The Californian industry learned a hard lesson following the destruction of more than 10 million gallons of wine. Before the earthquake, most of the wine was stored centrally; however, following the earthquake, major restructuring occurred, and wineries were from then on constructed closer to vineyards.

July 2, 1993 – On this day the Oakville AVA was founded. The AVA is the fourth from the north and south among Napa Valley AVAs. It is home to the Screaming Eagle Winery and Vineyards which produces the most expensive wines in America. Its first vintage was made in 1992 and released in 1995 at 75 dollars a bottle.[6] Currently, a bottle costs more than 7000 US dollars. The Oakville AVA produces fewer grapes but focuses on those that are in high demand.
