Rockpile AVA is an American Viticultural Area located in Sonoma County, California, northwest of the town of Healdsburg. Established on February 28, 2002, Rockpile AVA was Sonoma County's twelfth designated wine appellation. The wine region consists of approximately 15,400 acres (62 km2) in northwestern Sonoma County. All of the AVA has an elevation in excess of 800 feet (244 m) above sea level. Eleven vineyards are currently located within the AVA and there are approximately 160 acres (1 km2) of planted wine grapes.
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 McMinnville AVA is an American Viticultural Area located in Yamhill County, Oregon. It is entirely contained within the Willamette Valley AVA, roughly running from McMinnville to Sheridan. The AVA was created as a result of a successful petition from Kevin Byrd of Youngberg Hill Vineyards. McMinnville is one of few AVAs that is designated in part based on elevation, with vineyards required to be between 200 feet (61 m) and 1,000 feet (305 m) above sea level, where the soil and rock formations differ from surrounding areas. Primarily uplifted marine sedimentary loams and silt, the top soil is shallow and relatively infertile.
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 Snake River Valley AVA is an American Viticultural Area that encompasses an area in Southwestern Idaho and two counties in eastern Oregon. The Idaho Grape Growers and Wine Producers Commission and the Idaho Department of Commerce and Labor filed the petition to recognize the AVA, and it was granted in 2007.
The Virginia's Eastern Shore AVA is an American Viticultural Area that includes a 70 miles (113 km) length of Virginia's Eastern Shore and consists of the counties of Accomack and Northampton. The topography in this AVA is mostly level and ranges from sea level to 50 feet (15 m) above sea level. The area is located on the southern end of the Delmarva Peninsula. The weather in the area is characterized by temperate summers and winters, significantly affected by the Chesapeake Bay and the Atlantic Ocean. The soil is sandy and deep.
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.
The Chalk Hill AVA is an American Viticultural Area (AVA) located in Sonoma County, California. The boundaries of the wine appellation cover the northeast corner of the Russian River Valley AVA. The majority of vineyards are located to the east of U.S. Route 101, near the town of Windsor. The name Chalk Hill comes from the unique volcanic soil of chalky white ash which has shown itself to perform well with planting of white wine varietals like Chardonnay and Sauvignon blanc. The majority of the region's wineries are located on the western slopes of the Mayacamas Mountains.
The Northern Sonoma AVA is an American Viticultural Area in Sonoma County, California, United States. The appellation covers most of the county with the notable exceptions of the Los Carneros AVA and Sonoma Valley AVA wine regions, which are located in the southern portion of the county. The creation of this AVA was largely based on the petitioning of the E & J Gallo Winery as part of their expansion of their Gallo of Sonoma brand. The viticultural area incorporates the Alexander Valley AVA, Chalk Hill AVA, Dry Creek Valley AVA, Knights Valley AVA, Russian River Valley AVA, Sonoma Coast AVA, and parts of the Green Valley of Russian River Valley AVA and Rockpile AVA valleys.
The Sonoma Coast AVA is an American Viticultural Area in Sonoma County, California, United States containing more than 500,000 acres (2,000 km2), mostly along the coastline of the Pacific Ocean. It extends from San Pablo Bay to the border with Mendocino County. The appellation is known for its cool climate and high rainfall relative to other parts of Sonoma County. The area has such a broad range of microclimates that petitions have been made to the United States Department of the Treasury Alcohol and Tobacco Tax and Trade Bureau for the creation of sub-AVAs such as the Fort Ross-Seaview AVA which was approved in December 2011.
The Howell Mountain AVA is an American Viticultural Area located within Napa Valley AVA of 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 Sonoita AVA is an American Viticultural Area located in southeast Arizona, south of the city of Tucson. The Sonoita area is a basin surrounded by three mountain ranges, the Huachuca Mountains, the Santa Rita Mountains, and the Whetstone Mountains. The vineyard plantings are 4,500 to 5,000 feet above sea level, some of the highest in North America. The soil is alluvial fans of gravelly loam that retains scarce water well.
The West Elks AVA is an American Viticultural Area located in Delta County, Colorado in and around the towns of Cedaredge, Hotchkiss and Paonia. It is one of two AVA's in the state. Some of the highest altitude vineyards in the northern hemisphere are planted within the AVA. Located within the North Fork Valley of the Rocky Mountains in west central Colorado, vineyards in the AVA range from 5,400 to 6,400 feet (1,646–1,951 m) above sea level. The surrounding mountains limit access to the area, resulting in a far more secluded wine industry when compared to its nearby neighbor to the northwest, the Grand Valley AVA.
The Lake Wisconsin AVA is an American Viticultural Area located in south central Wisconsin. The wine growing region borders both Lake Wisconsin and the Wisconsin River. The first grapes were planted in the area by Agoston Haraszthy in 1847, before he migrated to California. Most vineyards in the area are planted at elevations between 800 feet (240 m) and 900 feet (270 m) above sea level. The area soils are gravel and sandy loam from glacial deposits. French hybrid grapes have had the most success in the Lake Wisconsin area, and the most important grape varietal grown in the area is Marechal Foch.
The Western Connecticut Highlands AVA is an American Viticultural Area that includes all of Litchfield and parts of Fairfield, New Haven, and Hartford counties in Connecticut. The Connecticut Highlands are far enough away from Long Island Sound that there is little of the moderating effect on climate that large bodies of water produce. The region is relatively cool, with a short growing season between mid-May and mid-September. The soil in the area is glacial schist and gneiss. Local vintners have had the most success with cool climate Vitis vinifera and French hybrid grape varieties. The region is located in hardiness zones 5b and 6a.
The Southeastern New England AVA is an American Viticultural Area that includes portions of thirteen counties in three New England states: Connecticut, Massachusetts, and Rhode Island. The boundaries of the wine appellation include parts of New Haven, New London, and Middlesex counties in Connecticut; Bristol, Newport, Providence, and Washington counties in Rhode Island; and Barnstable, Bristol, Dukes, Nantucket, Norfolk, and Plymouth counties in Massachusetts. The area stretches from just south of Boston, Massachusetts in the east to New London, Connecticut in the west, and includes all of the coastal islands and coastal plain within 15 miles (24 km) of Long Island Sound, Cape Cod, or Massachusetts Bay.
The Long Island AVA is an American Viticultural Area encompassing Nassau and Suffolk counties of New York, including the smaller offshore islands in those counties. The AVA was established in 2001, over 15 years after two smaller AVAs were created at the eastern end of Long Island. The Long Island AVA designation was promoted as a benefit for some wineries located just outside the two smaller AVAs and for wineries that wanted to create wines that use blends from vineyards in different parts of the island. It was also developed and promoted as a consumer protection of the Long Island name, as AVAs require that at least 85% of the fruit used in the designated wine is grown within the borders of the region. The "Long Island" AVA was authored by veteran Long Island winemaker Richard Olsen-Harbich who also authored "The Hamptons, Long Island" and "North Fork of Long Island" AVAs in the mid-1980s.
