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.
Arroyo Seco is an American Viticultural Area (AVA) in Monterey County, California, southeast of Monterey Bay. The appellation encompasses 18,240 acres (29 sq mi) in the valley adjacent to the Arroyo Seco Creek with approximately 8,500 acres (3,440 ha) of cultivation. The region's proximity to the Pacific Ocean produces the maritime climate, and is best suited for those cool climate grape varieties.
Willamette Valley is an American Viticultural Area (AVA) which lies in the Willamette Valley of Oregon. The AVA is the wine growing region which encompasses the drainage basin of the Willamette River. It stretches from the Columbia River in the north to just south of Eugene in the south, where the Willamette Valley ends; and from the Oregon Coast Range in the west to the Cascade Mountains in the east. At 5,360 square miles, it is the largest AVA in the state, and contains most of the state's wineries; approximately 908 as of 2021.

The wine region is entirely included within the larger Columbia Valley AVA. In addition to grapes, the area produces sweet onions, wheat and strawberries After the Yakima Valley AVA, the Walla Walla AVA has the second highest concentration of vineyards and wineries in Washington State. Walla Walla hosts about 140 wineries. The area was recognized on March 7, 1984 by the Bureau of Alcohol, Tobacco and Firearms (ATF), Treasury after reviewing the petition submitted by Mr. Richard L Small, President of the Walla Walla Valley Winegrowers Association, for the establishment of a viticultural area in southeast Washington and northeast Oregon, east of Lake Wallula, to be known as "Walls Walls Valley."

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.

Within the multi-county AVA are numerous established appellations that share the same maritime climate produced by the Pacific Ocean.
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.
Sierra Foothills is a vast American Viticultural Area (AVA) encompassing the foothill "belt" of the Sierra Nevada in north-central California, United States.

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).
