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.
Temecula Valley is an American Viticultural Area (AVA) in the Temecula Valley, located in southwestern Riverside County, California against the eastern slopes of the Santa Ana Mountains. It was initially established by the Bureau of Alcohol, Tobacco and Firearms (ATF), Treasury as "Temecula" on October 23, 1984 based on submitted petitions from by the Rancho Califomia/Temecula Winegrowers Association and Callaway Vineyard and Winery, Temecula, California in 1982. It was renamed "Temecula Valley" by the Alcohol and Tobacco Tax and Trade Bureau (TTB) in 2004, approving the 2001 petition by Temecula Valley Winegrowers Association. The petition stated the name change would provide a more accurate description of the Temecula geography and greater clarity as to its location for wine consumers and the public. The petition did not request any change to the established AVA boundaries. This was the first American Viticultural Area to change its name after the initial approval. Temecula Valley encompasses 33,000 acres (52 sq mi) and 5,000 acres (8 sq mi) is located in a "protected" area referred to as the Citrus/Vineyard Zone. This area is generally located in and around the Rancho California Road area with Riverside County. County guidelines strictly enforce the number of acres needed to build a winery, lodging and other limited housing and commercial ventures.
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 San Francisco Bay AVA is an American Viticultural Area (AVA) centered on the San Francisco Bay Area of Northern California. It was established on March 22, 1999 by the Bureau of Alcohol, Tobacco and Firearms (ATF), Treasury after reviewing the petition submitted by a consortium of nearly 75 growers and vintners led by Wente Bros. to establish a new viticultural area in Northern California known as "San Francisco Bay" to be within the Central Coast viticultural area. The San Francisco Bay AVA includes the counties of Alameda, Contra Costa, Santa Clara, San Francisco and San Mateo as well as parts of Santa Cruz and San Benito counties. The AVA was established by the Alcohol and Tobacco Tax and Trade Bureau (TTB) in 1999 and encompasses over 1,566,720 acres (2,448 sq mi). The AVA falls within the larger Central Coast AVA and contains five designated sub-region AVAs within its boundaries; Lamorinda AVA, Livermore Valley AVA, Pacheco Pass AVA, San Ysidro District AVA, and Santa Clara Valley AVA.
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 North Coast AVA is an American Viticultural Area in the state of California that encompasses grape-growing regions in six counties located north of San Francisco: Lake, Marin, Mendocino, Napa, Sonoma, and Solano. This large appellation covers over 3,000,000 acres (5,000 sq mi) and includes a number of smaller sub-appellations that all share the common ecology trait of weather affected by the fog and breezes off the Pacific Ocean.
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."
Edna Valley is an 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 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.
Lake County wine is a appellation that designates wine made from grapes grown mostly in Lake County, California and located north of Napa County. Although each region within Lake County has unique viticultural attributes, all are influenced by Clear Lake, the largest inland body of water in California. 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). TTB was created in January 2003, when the Bureau of Alcohol, Tobacco and Firearms, or ATF, was extensively reorganized under the provisions of the Homeland Security Act of 2002.
Red Hills Lake County AVA is an American Viticultural Area (AVA) located in Lake County, California and was established by Alcohol and Tobacco Tax and Trade Bureau (TTB), Treasury on September 10, 2004.

It lies within the Gabilan Mountains at elevations of 1,800 feet (550 m) to 2,200 feet (670 m) above sea level where the soil is predominantly limestone. The AVA was established as the result of a petition to the ATF by Josh Jensen and the Calera Wine Company, the only commercial winery in the appellation at the time.
York Mountain is an American Viticultural Area (AVA) in San Luis Obispo (SLO) County, California. It lies within the larger Central Coast AVA located on the eastern side of the Santa Lucia Mountains and west of Paso Robles viticultural area. The mountainous terrain features vineyards that are mostly cultivated at an elevation around 1,500 feet (460 m). York Mountain climate is cooler and wetter than Paso Robles being just 8 miles (13 km) from the Pacific Ocean. York Mountain viticultural area was recognized as the county’s second AVA by the Bureau of Alcohol, Tobacco and Firearms (ATF) effective on September 23, 1983 after reviewing the petition submitted by Stephen and Max Goldman, owners of York Mountain Winery, to establish a area known as “York Mountain.” Historically, Andrew York, a British immigrant, planted the first vineyard on York Mountain in the 1870s and established Ascension Winery, the first bonded winery in the Central Coast. It survived through Prohibtion and later renamed York Mountain Winery, staying in the York family until 1970 when it was purchased by Max Goldman.
Sta. Rita Hills is an American Viticultural Area located in Santa Barbara County, California. From its creation in 2001 through 2006, the wine appellation was officially named Santa Rita Hills AVA. The formal name change was the result of a protest by and subsequent negotiations with Vina Santa Rita, a very large Chilean wine producer that was concerned about the AVA name diluting its international brand value. The name change took effect on January 5, 2006, with a yearlong period for producers in the AVA to change their wine labels. In 2016, TTB expanded the approximately 33,380 acres (52 sq mi) “Sta. Rita Hills” viticultural area by approximately 2,296 acres (4 sq mi).

It is part of the larger Central Coast AVA, and contains the greatest concentration of wineries in Santa Barbara County. The valley is formed by the Purisima Hills and San Rafael Mountains to the north and the Santa Ynez Mountains to the south creating a long, east-west corridor with very cool temperatures on the coast that become progressively warmer inland. The Santa Ynez River flows east to west on the valley floor toward the Pacific Ocean. As of 2021, the Santa Ynez Valley contains four other established viticultural areas: Sta. Rita Hills on its western boundary; Ballard Canyon and Los Olivos District occupying the center region; and Happy Canyon on the eastern border. Chardonnay is the most planted grape variety in the cooler, western portion of the valley while Rhône varieties thrive in the eastern locales.

San Luis Obispo Coast and SLO Coast identify the sixteenth American Viticultural Area (AVA) within San Luis Obispo County, California. It was established by the Alcohol and Tobacco Tax and Trade Bureau (TTB) on April 8, 2022, becoming the state's 143rd official AVA. The area encompasses over 480,585 acres (750.914 sq mi) nestled between the Santa Lucia mountains and the Pacific coastline stretching about 70 miles (110 km) from Ragged Point southbound on the Pacific Coast Highway (PCH) and Highway 101 to the outskirts of Santa Maria at the intersection of State Highway 166 and Highway 101. It includes the coastal communities of San Simeon, Cambria, Cayucos, Morro Bay, Avila Beach, Pismo Beach, Arroyo Grande and Nipomo while encompassing the county seat of San Luis Obispo. The TTB approved the petition's two names, "San Luis Obispo Coast" and "SLO Coast", to identify the viticultural area's description and wine labeling.
