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.
The state of Oregon in the United States has established an international reputation for its production of wine, ranking fourth in the country behind California, Washington, and New York. Oregon has several different growing regions within the state's borders that are well-suited to the cultivation of grapes; additional regions straddle the border between Oregon and the states of Washington and Idaho. Wine making dates back to pioneer times in the 1840s, with commercial production beginning in the 1960s.
The Willamette Valley AVA is an American Viticultural Area 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 (13,900 km2), it is the largest AVA in the state, and contains most of the state's wineries; approximately 908 as of 2021.
The Southern Oregon AVA is an American Viticultural Area which lies in Southern Oregon, United States. The Southern Oregon AVA was established in 2005 and was created to include the land of two smaller AVAs: the Rogue Valley AVA and the Umpqua Valley AVA. Southern Oregon AVA was established to allow the two principal winegrowing regions in the southern part of the state to market themselves jointly. This creation of a "super-AVA" is a departure from the trend in the Willamette Valley AVA or northern Oregon of establishing smaller AVAs specific to a particular locale's climate or soil conditions.
The Yamhill-Carlton AVA is an American Viticultural Area located in both Washington County and Yamhill County, Oregon. It is entirely contained within the Willamette Valley AVA, and surrounds the towns of Carlton and Yamhill. The mountain ridges surrounding the AVA form a horseshoe shape, and most of the vineyards are located on south-facing slopes. The AVA includes only land between 200 feet (61 m) and 1,000 feet (305 m) above sea level where marine sediments are some of the oldest soils in the Willamette Valley and create unique conditions for viticulture. The region is in the rain shadow of the 3,500 feet (1,100 m) Oregon Coast Range, a short distance to the west.
The Ribbon Ridge AVA is an American Viticultural Area in Yamhill County, Oregon. It is the smallest AVA in Oregon and is entirely contained within the Chehalem Mountains AVA, which in turn is entirely contained within the larger Willamette Valley AVA. Ribbon Ridge stretches between the towns of Newberg and Gaston. The ridge is defined by local geographic boundaries and an uplift of ocean sediment. It lies at 45° 21' N latitude and 123° 04' W longitude, at the northwest end of the Chehalem Mountains. Colby Carter, an early settler from Missouri, named Ribbon Ridge in 1865, and the ridge has been known by that name ever since. The first official use of the Ribbon Ridge name dates to 1888 with the creation of Ribbon Ridge School District No. 68. The ridge is approximately 0.25 miles (0.40 km) wide and 3.50 miles (5.63 km) long, and is 3,350 acres (1,356 ha) in area, with 500 acres (202 ha) planted on 20 vineyards. It is estimated that between 1,000 acres (405 ha) and 1,400 acres (567 ha) in the region is suitable for planting.
The Augusta AVA was established on June 20, 1980 as the first federally approved American Viticultural Area, eight months before the Napa Valley AVA in northern California. The petition was submitted by Clayton W. Byers and Lucian W. Dressel, representing the local wine industry, to the Director of the Bureau of Alcohol, Tobacco and Firearms on October 16, 1978. Located entirely within the state of Missouri, the boundaries of this wine region encompass 15 square miles (39 km2) around the city of Augusta near the intersection of St. Charles County, Warren County and Franklin County.
Sonoma County wine is wine made in Sonoma County, California, in the United States.
The Santa Cruz Mountains AVA is an American Viticultural Area centered on the Santa Cruz Mountains. Its territory expands 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.
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."
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.
Lake County wine is an 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. Lake County enjoys a reputation for bright, concentrated red wines made from Cabernet Sauvignon, Syrah and Zinfandel, and fresh, aromatic whites made from Sauvignon Blanc. Cabernet Sauvignon has the most acreage, with Merlot a distant second.

The Eola-Amity Hills AVA is an American Viticultural Area located in Polk County and Yamhill County, Oregon. It is entirely contained within the Willamette Valley AVA, and stretches from the city of Amity in the north to Salem in the south. The Eola and Amity hills cover an area west of the Willamette River approximately 15 miles (24 km) long by 6 miles (10 km) wide. The Eola-Amity Hills area benefits from steady winds off the Pacific Ocean that reach the Willamette Valley through the Van Duzer Corridor, a gap in the Oregon Coast Range, moderating the summer temperatures. The Eola Hills were named after the community of Eola, whose name was derived from Aeolus, the Greek god of the winds.

The Wisconsin Ledge AVA is an American Viticultural Area in northeast Wisconsin along the Niagara Escarpment in Door, Kewaunee, Manitowoc, Sheboygan, Ozaukee, Washington, Dodge, Fond du Lac, Calumet, Outagamie, and Brown counties. Certified by the United States Department of the Treasury's Alcohol and Tobacco Tax and Trade Bureau on March 22, 2012, it covers an area of 3,800 sq mi (9,800 km2) and is the second AVA designation wholly in Wisconsin, following the Lake Wisconsin AVA established in 1994. The state's third is the gargantuan Upper Mississippi River Valley AVA which also covers land in Minnesota, Iowa and Illinois. After 7 long years, and 4000 hours, Steven J. DeBaker of Trout Springs Winery was granted his petition to the TTB for establishment of the Wisconsin Ledge AVA. It became the 203rd AVA in the US, including just under 2.5 million acres making it the 12th largest AVA in the US. Today, there are 24 bonded wineries that lie within the AVA with over 400 acres of vines planted.

Tualatin Hills is an American Viticultural Area (AVA) located due west of Portland and just east from the Oregon Coast Range in the upland hills of the Tualatin River watershed and encompasses elevations between 200 and 1,000 feet. It was established on May 13, 2020 by the Alcohol and Tobacco Tax and Trade Bureau (TTB). It lies entirely within the northern most location of the Willamette Valley AVA in and around towns like Gaston, Forest Grove, Sherwood and Cornelius. To the south and southeast are the Chehalem Mountains with elevations of over 1,000 feet (300 m) and considered to be a separate, distinct landform from the uplands within Tualatin Hills. The region stretches over approximately 144,000 acres (225 sq mi) and contains 21 wineries with 33 commercially-producing vineyards that covers approximately 860.5 acres (348 ha). The distinguishing features of Tualatin Hills are its soils, elevation, and climate.
Petaluma Gap AVA is an American Viticultural Area established on January 8, 2018 by the U.S. Department of Treasury’s Alcohol and Tobacco Tax and Trade Bureau (TTB). The area spans 202,476 acres (316 sq mi) stretching through an 30 miles (48 km) inland valley from the Pacific coast at Bodega Bay southeast to Highway 37 at Sears Point on San Pablo Bay straddling the border of northern Marin and southern Sonoma counties. The AVA lies entirely within the North Coast AVA and partially in the Sonoma Coast AVA with eighty commercially-producing vineyards cultivating 4,000 acres (1,619 ha) and nine bonded wineries. The wind gap in its coastal mountain range funnels cooling breezes and fog east from the Pacific Ocean through the city of Petaluma to San Pablo Bay. A persistent afternoon breeze causes lower grape yields and longer hang time contributes to the AVA vintages' unique flavors and fruit characteristics which defines their character and distinction.
