An American Viticultural Area (AVA) is a designated wine grape-growing region in the United States, providing an official appellation for the mutual benefit of wineries and consumers. Winemakers frequently want their consumers to know about the geographic pedigree of their wines, as wines from a particular area can possess distinctive characteristics. Consumers often seek out wines from specific AVAs, and certain wines of particular pedigrees can claim premium prices and loyal customers. If a wine is labeled with an AVA, at least 85% of the grapes that make up the wine must have been grown in the AVA, and the wine must be fully finished within the state where the AVA is located.
Santa Maria Valley is an American Viticultural Area (AVA) which straddles the boundary of Santa Barbara and San Luis Obispo counties in California's multi-county Central Coast AVA. It was established on August 5, 1981, by the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) as California's second oldest AVA. A portion of the AVA crosses the Cuyama River into the southernmost corner of San Luis Obispo County. The east–west orientation of the 152.3 square miles with a wide, open valley and rolling hills means cool winds and fog flow in freely from the Pacific Ocean, settling most noticeably in lower-lying areas. The result is a mild Mediterranean climate that lengthens the growing season and contributes to the eventual sugar/acid balance in the grapes from Santa Maria Valley's 7,500 acres (3,000 ha) cultivated vineyards. On January 28, 2011, the AVA was granted an 29.4 square miles expansion to its southern boundary.
The Guenoc Valley AVA is an American Viticultural Area in Lake County, California, United States, about 15 mi (24 km) north of the town of Calistoga. Guenoc Valley AVA was the first American Viticultural Area designation granted to an area with just a single winery.

Monticello is an American Viticultural Area (AVA) located in the central Piedmont region of the Commonwealth of Virginia. It was established by the Bureau of Alcohol, Tobacco and Firearms (ATF) on February 22, 1984 after six wine grape growers in the Charlottesville area petitioned the ATF to designate a viticultural area to be known as “Monticello.” The name "Monticello" is known nationally and locally as the historic home of Thomas Jefferson, located near the center of the area. Monticello AVA includes most of Albemarle, Fluvanna, Greene, Orange, and Nelson counties. The area is nestled along the eastern slopes of the Blue Ridge Mountains and encompasses the small ridge known as the Southwest Mountains. There are approximately 30 varieties of grapes grown in the Monticello AVA. However, the most notable grapes grown in the area include Cabernet Franc, Chardonnay and Viognier. The hardiness zone is 7a except in some higher vineyards which are 6b. In 2019, the Tax and Trade Bureau (TTB) granted a petition to expand the AVA by approximately 106,240 acres (166 sq mi) into Fluvanna County.
Paso Robles is the third American Viticultural Area (AVA) located in San Luis Obispo (SLO) County, California. It was established by the Bureau of Alcohol, Tobacco and Firearms (ATF), Treasury on November 3, 1983 based on a petition submitted by Martin-Brothers Winery. The area encompasses 609,673 acres (953 sq mi) with approximately 18,500 acres (7,487 ha) cultivated with wine grapes known for their heritage varietal Zinfandel, Cabernet Sauvignon, and Rhône-style wines.
The Mendocino Ridge AVA is a coastal, cool climate and high altitude American Viticultural Area located entirely within the coastal zone of Mendocino County, California. The boundaries of the AVA encompass the coastal ridges adjacent to the Pacific Ocean that reach inland toward the Anderson Valley. Roughly 36 miles of the southernmost portion of the Mendocino Coast make up the western boundary of the AVA, with the Sonoma County line as the southern boundary, the Navarro River as the northern boundary and Anderson Valley as the inland boundary running northwest–southeast. The Mendocino Ridge AVA "is essentially a northern extension of the true Sonoma Coast viticultural area." However, the Mendocino Ridge AVA designation is unique in that it is limited by elevation, reserved only for vineyards at or above 1200 feet. This is why the Mendocino Ridge AVA has been nicknamed "Islands in the Sky®," because the vineyards sitting at 1200 feet or higher are often perched above thick fog moving inland from the Pacific Ocean blanketing the coast and the valleys between the ridge tops, making the tips of the mountains look like islands protruding from a sea of fog. In this overlapping, "[t]he Mendocino Ridge AVA floats above the Anderson Valley and Mendocino appellations." Mendocino Ridge is the only non-contiguous AVA in the United States; all others are contiguous landmasses with all vineyards inside the boundaries designated as part of the AVA, whereas Mendocino Ridge in comparison only includes the higher altitude growing sites. "There are 262,400 acres within the outer boundaries of the Mendocino Ridge viticultural area, but the actual viticultural area encompasses only 87,466 acres which lie above 1,200 feet elevation. Of these 87,466 acres, approximately 1,500 to 2,000 acres of the ridge tops are suitable for vineyards. The side-slopes are very steep and covered with timber, making them unfit for planting". Estimates of planted acres range from 233 to 410, which accounts for about 0.3% of the total area. These planted acres are scattered among 16 remote vineyards.
Arroyo Grande Valley is an American Viticultural Area (AVA) located in San Luis Obispo County, California approximately 12 miles (19 km) southeast of the county seat San Luis Obispo. Arroyo Grande Valley was recognized on February 5, 1990 by the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) as the state's 60th AVA based on the petition filed in 1987 by Don Talley of Talley Vineyards and William S. Greenough of Saucelito Canyon Vineyard for the establishment of the "Arroyo Grande Valley" viticultural area in San Luis Obispo County. The 16 miles (26 km) long, approximately 67 square miles valley appellation benefits from its east-northeast orientation allowing the breeze from the Pacific Ocean to moderate the climate of the area. The valley is divided by a fog line produced by the cool maritime layer where Zinfandel, Petite Sirah and Rhône varietals are grown on the higher elevations near Lopez Lake and the cooler mid-valley vineyards being home to Chardonnay and Pinot noir. On April 8, 2022, the Alcohol and Tobacco Tax and Trade Bureau (TTB) approved the designation of the expansive San Luis Obispo (SLO) Coast AVA overlapping the boundaries of Edna Valley and Arroyo Grande Valley viticultural areas because they share common features. However, these two previously established areas still have unique characteristics to retain their viticultural area distinctions within SLO Coast. Edna Valley lies immediately to the northwest, the Los Padres National Forest straddles the north leg boundary, the Santa Maria Valley AVA lies to the southeast of Arroyo Grande Valley, and the Pacific Ocean communities of Oceano, Grover City and Arroyo Grande abut its southwestern border.
The Santa Cruz Mountains AVA is an American Viticultural Area centered on the Santa Cruz Mountains. Its territory spans three California counties, Santa Clara, Santa Cruz and San Mateo. Established in 1981 by the Alcohol and Tobacco Tax and Trade Bureau (TTB), Santa Cruz Mountains AVA was among the first to be defined by its mountain topography. Based on elevation, it largely follows the fog line along the coast, extending down to 800 feet (240 m) on the eastern slope toward San Francisco Bay, 400 feet (120 m) on the western slope to the Pacific Ocean and extending toward the ridgecrests at 3000+ feet elevation.
Mount Veeder AVA is an American Viticultural Area located within Napa Valley AVA among the Mayacamas Mountains. The boundaries of this appellation include 25 sq mi (64.7 km2) with 1,000 acres (400 ha) planted on thin volcanic soil. Many vineyards are found on the steep mountain face some as steep as 30°. The steepness of the angle gives the vineyards benefits of more direct sunlight and better drainage.
The Oakville AVA is an American Viticultural Area located within Napa Valley AVA and centered on the town of Oakville, California. The appellation extends over a flat expanse of well-drained gravel soil between the Vaca and Mayacamas Mountains. Oakville AVA is known for its success with Bordeaux varietals, which have produced wines of rich texture, firm tannins, and notes of mint and herbs.
St. Helena is an American Viticultural Area (AVA) located within Napa Valley, centered in and around the town of St. Helena, California. It was established by the Bureau of Alcohol, Tobacco and Firearms (ATF) on October 11, 1995, after the ATF received a petition from Mr. Charles A. Carpy, Chairman of the St. Helena Appellation Committee, proposing to establish a new viticultural area in Napa County to be known as "St. Helena."
The Stags Leap District AVA is an American Viticultural Area located within the Napa Valley AVA 6 miles (9.7 km) north of the city of Napa, California. The Stags Leap District was the first appellation to be designated an AVA based on the unique terroir characteristics of its soil. The soil of this region include loam and clay sediments from the Napa River and volcanic soil deposits left over from erosion of the Vaca Mountains. Like many Napa Valley AVAs, Stags Leap District is particularly known for its Cabernet Sauvignon. In 1976 at the Judgment of Paris wine tasting, the 1973 Stag's Leap Wine Cellars Cabernet from the area that would become this AVA won first place in the red wine category, beating out classified Bordeaux estates. Today, the Stags Leap District is home to twenty different wineries.
The Chiles Valley is an American Viticultural Area (AVA) located in Napa County, California and a sub-region within Napa Valley AVA. It was established as California's 81st AVA by the Bureau of Alcohol, Tobacco and Firearms (ATF) on April 19, 1999 after the ATF received the petition from Mr. Volker Eisele, owner of the Volker Eisele Vineyard and Winery proposing a new viticultural area in Napa County to be known as "Chiles Valley District".
Edna Valley is a American Viticultural Area (AVA) located in San Luis Obispo (SLO) County, California encompassing the rural town of Edna which is 9 miles (14 km) southeast of the county seat San Luis Obispo and north of the small coastal town Arroyo Grande. It was established by the Bureau of Alcohol, Tobacco and Firearms (ATF) as the county's first AVA within California’s multi-county Central Coast AVA effective May 12, 1982. It became an sub-appellation of the county’s newest San Luis Obispo Coast viticultural area since April 2022. The valley is diagonally flanked by Lake Lopez to the south and Islay Hill to the north. The elongated valley extends along a northwest-southeast axis bordered to the west by the Santa Lucia Mountains and surrounded by volcanic mountains and characterized by black humus and clay-rich soils. With moderate sunshine, cool maritime fog, and rich oceanic and volcanic soils, the Edna Valley appellation has California's longest growing season. The valley is kept cool by breezes from the Pacific Ocean and morning fog. The extended growing season allows complex flavors to develop in the grapes.
Leona Valley AVA is an American Viticulture Area (AVA) in northeastern Los Angeles County, California. It is located in Leona Valley within the Sierra Pelona Mountains of Southern California.
West Elks is an American Viticultural Area located in Delta County on the Western Slope of Colorado within the North Fork Valley surrounding the towns of Cedaredge, Hotchkiss and Paonia. It was established by the Bureau of Alcohol, Tobacco and Firearms (ATF) effective May 7, 2001 and is the latest of the two registered viticultural areas in the "Centennial State." The viticultural area takes its name from the nearby West Elk Mountains. The area is located on mesa lands with 48,405 acres (76 sq mi) expanding along the North Fork Gunnison River from the historic mining town of Bowie, through Paonia and Hotchkiss. Its borders are the West Elk Range to the east and the higher Grand Mesa to the north. To the south, Crawford and Fruitland Mesa have higher elevations and the plateau climbs until it reaches the north rim of Black Canyon of the Gunnison. To the west lies the barren Adobe Badlands which has little plant growth. State Highway 133 bisects the AVA in a north-south direction. The high-altitude vineyards are situated mostly at 5,400 to 6,400 feet (1,600–2,000 m) above sea level. The USDA plant hardiness zone is 7a.
Adelaida District is a American Viticultural Area (AVA) located on the north west portion of the Paso Robles AVA in San Luis Obispo (SLO) County, California.

Santa Barbara County wine is an appellation that designates wine made from grapes grown mostly in Santa Barbara County, California which is located approximately 50 miles (80 km) north of Los Angeles County. County names in the United States automatically qualify as legal appellations of origin for wine produced from grapes grown in that county and do not require registration with the United States Department of the Treasury Alcohol and Tobacco Tax and Trade Bureau. Viticulture in Santa Barbara County is traceable to missionary plantings in the Milpas Valley late in the 18th century when Spanish Jesuit missionaries planted Vitis vinifera vines native to the Mediterranean region in their established missions to produce wine for religious services. In the 1770s, Spanish missionaries continued the practice under the direction of Father Junipero Serra who brought grapevine cuttings from Mexico to be planted near Sycamore Creek. Since commercial viticulture rebounded in the 1960s, Santa Barbara County has been on the fast track to viticultural stardom. Its grapes now command among the highest prices anywhere in the state. In 1965, soil and climatic studies indicated that the Santa Ynez and Santa Maria valleys offered suitable conditions for growing high-quality wine grapes. Thus launched a revival of the area's two-centuries-old wine industry which, in 1995, made Santa Barbara County an internationally prominent wine region. The county is famous for its primer Chardonnay and Pinot Noir and gaining a reputation for Rhone varietals including Syrah and Viognier,
San Luis Obispo (SLO) County wine is a appellation that designates wine made from grapes grown in San Luis Obispo (SLO) County, California which is sandwiched between Santa Barbara County to the south and Monterey County at the northern boundary on the Pacific coast. Its location sits halfway between the cities of San Francisco and Los Angeles on the north–south axis of U.S. Route 101 and Pacific Coast Highway (PCH). The county lies entirely within the Central Coast viticultural area. County names in the United States automatically qualify as legal appellations of origin for wine produced from grapes grown in that county and do not require registration with the Alcohol and Tobacco Tax and Trade Bureau (TTB), Treasury. The term "SLO" is a historical and commonly used reference for the county and its county seat, San Luis Obispo, initials as well as a description of the region's relaxed culture. According to the U.S. Census Bureau, the county has a total area of 3,616 square miles of which 3,299 square miles is land and 317 square miles (820 km2) is water. San Luis Obispo county is home to some of California's coolest winemaking areas similar to climatic influences as its northern counterparts, Napa and Sonoma counties. The proximity of the Pacific coastline to the viticultural areas of San Luis Obispo Coast (SLO) Coast, and at the county's southern end, Arroyo Grande Valley, influences their vineyards to the cool marine air.
