Rocky Reach is an American Viticultural Area (AVA) located within portions of Chelan and Douglas Counties between the cities Chelan and Wenatchee in central Washington state. The area is an elongated strip of land that straddles the Columbia River entirely within the vast Columbia Valley AVA. Rocky Reach is the state's 20th AVA recognized by the Alcohol and Tobacco Tax and Trade Bureau {TTB), Treasury on July 5, 2022, after reviewing the petition submitted by Whitman College professor and geologist, Dr. Kevin Pogue, on behalf of regional winemakers and vineyard owners, to establish a viticultural area named "Rocky Reach." [1] [7] [8] [9]
The name "Rocky Reach" originated from 19th-century nautical nomenclature where steamboat captains navigating the Columbia River describe the rapids in a particularly rocky "stretch" or "reach" of the river. The AVA encompasses 32,000 acres (50 sq mi) with the Columbia River and the Rocky Reach Reservoir constituting approximately 24 percent of the total area. There are 7 commercial vineyards with approximately 117 acres (47 ha) under vine with a sole winery. [1] [10]
The distinguishing features of the Rocky Reach AVA are its topography, geology, soils, and climate. Rocky Reach AVA is located along a stretch of the Columbia River where the river has eroded a deep canyon between the foothills of the Cascade Range to the west and the Waterville Plateau and Badger Mountain to the east. Elevations within the AVA are below 1,600 ft (488 m). Near the floor of the canyon and along the canyon sides are flat-topped terraces. According to the petition, the terraces within the AVA have long been used for agricultural purposes, including viticulture, due to the ease of farming on the nearly level ground. West of the Rocky Reach. the terrain is rugged and mountainous and elevations rise rapidly to over 3,000 ft (914 m). To the east of the viticultural area, elevations are also higher, rising to an average of 2,500 ft (762 m) on the Waterville Plateau. According to the petition, the terrain is much steeper to the east of the AVA. To the north, within the established Lake Chelan AVA, glaciers eroded a deep and broad glacial trough that is now filled by Lake Chelan. South of the Rocky Reach, the valley of the Columbia River abruptly widens where the bedrock changes from hard, erosion-resistant metamorphic rocks to much softer sedimentary rocks. [7]
According to the petition, 95 percent of the surface bedrock within the established Columbia Valley AVA consists of Cenozoic volcanic and sedimentary rock, predominantly Miocene Columbia River basalt, which is silica-poor and iron-rich. However, within the Rocky Reach AVA, erosion has removed the basalt and carved a deep valley into the underlying Mesozoic crystalline basement rocks. According to the petition, the region north of the AVA, specifically the established Lake Chelan AVA, is the only other region within the Columbia River AVA that has this crystalline basement bedrock. These rocks consist primarily of metamorphosed sedimentary and igneous rocks that are silica-rich and dominated by minerals like quartz and mica that are not found in the regions to the east, south, and west of the AVA, which has basalt bedrock. As a result, grapevine roots that reach the bedrock of the AVA come into contact with a chemical environment that is distinct from that associated with basalt bedrock. [3] [7]
The petition states that the soils of the AVA formed from wind-deposited sand and silt overlying cobblestone gravel, as well as from sand deposited by ice-age floods. The soils are typically clay-poor and well- to excessively well-drained. The thickness of the sand and silt is generally greater on the higher terraces within the proposed AVA, as their greater age has allowed more time for soils to be deposited. Most of the vineyards in the AVA are on the lower terraces, where the soils are very coarse-grained and consist largely of cobblestones deposited by glacial floods and outwash. According to the petition, the stony surfaces of the lower terraces warm quickly. The hot stones then radiate heat to the vines, promoting faster and more complete ripening. The coarse soils also more efficiently transmit water to deeper soil horizons, which encourages deeper root penetration than in silty or sandy soils. Finally, the petition notes that vineyards in stony soils do not require the use of cover crops since erosion is not an issue due to the coarse texture. To the north of the AVA, the soils of the glaciated valleys formed from glacial till, which is sediment deposited directly by melting glacial ice. The soils also contain volcanic ash and pumice, which are uncommon within Rocky Reach AVA. Fine-grained loess and sand over a basalt substratum dominate the soils in the regions to the south and east of Rocky Reach AVA. [3]
Rocky Reach AVA's location at low elevations within the deep valley of the Columbia River allows it to have a warmer and longer growing season than the higher elevations of the surrounding mountains and plateaus. The petition included data on temperatures for the period of 2015–2017 measured at two locations within the proposed AVA and two locations in the region to the north of the proposed AVA. The data indicates that the Rocky Reach AVA generally has warmer average annual temperatures than the regions to the north and higher maximum temperatures. During the three-year period, the average temperature within the proposed Rocky Reach AVA was 64.7 °F (18.2 °C), with an average maximum temperature of 77.9 °F (25.5 °C). The highest maximum temperature measured during that period was 108.9 °F (42.7 °C). The average minimum temperature within the AVA was 52 °F (11 °C). The lowest minimum temperature was 29.2 °F (−1.6 °C). The average soil temperature was 68.8 °F (20.4 °C). By comparison, during the same three-year period, the average temperature within the region to the north of the AVA was 63 °F (17 °C), with an average maximum temperature of 74.9 °F (23.8 °C). The highest maximum temperature measured during that time period was 105.4 °F (40.8 °C). The average minimum temperature within the region to the north was the same as within the AVA, and the lowest minimum temperature was 29.9 °F (−1.2 °C), which was similar to the lowest minimum temperature within the AVA. The average soil temperature was 56.5 °F (13.6 °C). [3]
Rocky Pond Estate Winery planted the first vineyard in the Rocky Reach locale in 2013. The winery subsequently planted a second vineyard in 2018 and another in the neighboring Lake Chelan AVA. Currently, Rocky Pond is the only winery within the appellation. When the TTB recognized the Rocky Reach appellation in July 2022, there were seven commercial vineyards with approximately 117 acres (47 ha) under vine. [6]
Livermore Valley is an American Viticultural Area (AVA) in Alameda County, California, centered around the city of Livermore in the Tri-Valley region which is composed of Amador, San Ramon, and Livermore valleys. The valley was named by Robert Livermore, an 18th century landowner whose holdings encompassed the area who planted the first grapevines in the region. The 96,000 acres (150 sq mi) AVA was established on September 1, 1982 by the Bureau of Alcohol, Tobacco and Firearms (ATF), Treasury after reviewing the petition submitted by fifteen Livermore Valley vintners and growers to establish a viticultural area in Alameda County named "Livermore Valley."
Yadkin Valley is an American Viticultural Area (AVA) expanding across seven counties of northwestern North Carolina encompassing approximately 1,416,600 acres (2,213 sq mi) in the Yadkin River Valley. The appellation includes all of Wilkes, Surry, and Yadkin counties, and portions of Davie, Davidson, Forsyth, and Stokes counties. It was recognized on February 7, 2003, by the Bureau of Alcohol, Tobacco and Firearms (ATF), Treasury after reviewing the petition submitted by Patricia McRitchie of McRitchie Associates, LLC, on behalf of Shelton Vineyards, Inc., Dobson, North Carolina, to establish the initial viticultural area within the State of North Carolina, to be known as "Yadkin Valley." At the time, there were over 30 growers cultivating approximately 350 acres (142 ha) and three bonded wineries with at least two others under construction.
Washington wine is a wine produced from grape varieties grown in the U.S. state of Washington. Washington ranks second in the United States in the production of wine. By 2017, the state had over 55,000 acres (220 km2) of vineyards, a harvest of 229,000 short tons (208,000 t) of grapes, and exports going to over 40 countries around the world from the 940+ wineries located in the state. While there are some viticultural activities in the cooler, wetter western half of the state, the majority (99.9%) of wine grape production takes place in the shrub-steppe eastern half. The rain shadow of the Cascade Range leaves the Columbia River Basin with around 8 inches (200 mm) of annual rain fall, making irrigation and water rights of paramount interest to the Washington wine industry. Viticulture in the state is also influenced by long sunlight hours and consistent temperatures.
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.
Columbia Gorge is an American Viticultural Area (AVA) that encompasses a region within the 40 miles (64 km) Columbia River Gorge and straddles the Oregon and Washington state border. The AVA was established by the Alcohol and Tobacco Tax and Trade Bureau {TTB), Treasury on July 9, 2004 after reviewing the petition submitted by Mark Wharry, on behalf of the Columbia River Gorge Wine Growers Association, proposing the viticultural area named "Columbia Gorge." The 280 square miles AVA is located about 60 miles (97 km) east of Portland, Oregon, straddles the Columbia River for 15 miles (24 km), and extends into south-central Washington and north-central Oregon. The area surrounds Hood River, Oregon, and White Salmon, Washington, and is generally bordered by B Z Corner, Washington, on the north; Lyle, Washington, on the east; Parkdale, Oregon, on the south; and Vinzenz Lausmann State Park, Oregon, on the west. The area lies due west with an adjacent border to the vast Columbia Valley viticultural area. Due to the significant gradations of climate and geography found in the gorge, the AVA exhibits a wide range of terroir in a relatively small region; it is marketed as a "world of wine in 40 miles".
Columbia Valley is an American Viticultural Area (AVA) which lies within the Columbia River Plateau, through much of central and southern Washington state, with a section crossing the state boundary into northern Oregon south of the Columbia River. The viticultural area includes the drainage basin of the Columbia River and its tributaries through much of Washington. It was established by the Bureau of Alcohol, Tobacco and Firearms (ATF), Treasury on December 13, 1984 after evaluating the petition filed by Drs, Walter Clore and Wade Wolfe of Prosser, Washington on behalf of Washington’s oldest and largest winery, Chateau Ste. Michelle, and by William Blosser of the Sokol Blosser Winery, Dundee, Oregon. Allen Shoup, president of Chateau Ste. Michelle, understood the importance of obtaining appellation status to grow the reputation of the Northwest viticulture industry.
Mendocino Ridge is a coastal, cool climate and high altitude American Viticultural Area (AVA) located entirely within the coastal zone of Mendocino County, California. The viticultural area was established on October 27, 1997 by the Bureau of Alcohol, Tobacco and Firearms (ATF), Treasury after reviewing the petition submitted by Mr. Steve Alden on behalf of the Mendocino Ridge Quality Alliance proposing a viticultural area named "Mendocino Ridge." The boundaries of the 262,400 acres (410 sq mi) AVA encompass the coastal ridges at or above 1,200 ft (366 m) in elevation adjacent to the Pacific Ocean that reach inland toward the Anderson Valley. Roughly 36 mi (58 km) of the southernmost portion of the Mendocino coastline forms the AVA western border, with the Sonoma County line as the southern boundary, the Navarro River is the northern boundary and Anderson Valley outlines the inland boundary running northwest–southeast. Mendocino Ridge is essentially a northern extension of the Sonoma Coast viticultural area. Mendocino Ridge AVA designation is unique by its elevation where vineyards lie at or above 1,200 ft (366 m). This means Mendocino Ridge is the only non-contiguous AVA in the United States. The Mendocino Ridge AVA has been nicknamed "Islands in the Sky," because the thick fog moving inland from the Pacific Ocean blankets the coast and the valleys between the ridge tops, making the tops of the mountains, where the vinyards lay, look like islands protruding from a sea of fog. Mendocino Ridge AVA lies above the Anderson Valley and Mendocino appellations. The Mendocino Ridge viticultural area contains approximately 1,500 to 2,000 acres (607–809 ha), about 2% of the total acreage, that are suitable for vineyards. The local hillsides are very steep and covered with timber, making them unfit for viticulture. Estimates of planted acres range from 233 to 410, which accounts for about 0.3% of the total area.
San Pasqual Valley is an American Viticultural Area (AVA) in northern San Diego County, California. It is located in the thin San Pasqual Valley of the Peninsular Ranges which runs inland from the city of Escondido north of the city of San Diego. The 9,000 acres (14 sq mi) AVA was established on August 17, 1981 by the Bureau of Alcohol, Tobacco and Firearms (ATF), Treasury after reviewing the petition submitted by a representative of San Pasqual Vineyards to establish a viticultural area in San Diego County to be named "San Pasqual Valley." San Pasqual Valley was the nation's fifth American Viticultural Area wine region established in 1981.
Grand Valley is an American Viticultural Area (AVA) within Mesa County, Colorado located in a high-altitude river valley surrounding the county seat of Grand Junction and stretching 24 miles (39 km) east-west between the municipalities of Palisade and Fruita. It lies approximately 200 miles (320 km) west-southwest of Denver along Interstate 70. The river valley encompasses 75,990 acres (118.73 sq mi), with an average elevation between 4,000 and 5,000 feet (1,200–1,500 m) above sea level and is defined by an irrigated agricultural area served by canals in the Grand Valley of the Colorado River. Grand Valley AVA was established by the Bureau of Alcohol, Tobacco and Firearms (ATF) on December 26, 1991, upon the petition submitted by Mr. James Seewald of Vintage Colorado Cellars Winery, and the first viticultural area registered in the Centennial State. In 2001, the smaller West Elks AVA, located southeast of Grand Valley, became the state's second federally-designated AVA.
Lake Chelan is an American Viticultural Area (AVA) in Washington state. The appellation lies about 112 miles (180 km) northeast of Seattle located in north-central Washington's Lake Chelan Valley and is a sub-appellation of the vast Columbia Valley AVA. It lies east of the Puget Sound viticultural area and north or west of the other Washington State viticultural areas. It borders the Columbia Valley viticultural area on is eastern side and does not include any portion of other Washington viticultural areas except the Columbia Valley AVA.
Swan Creek is an American Viticultural Area (AVA) located in northwestern North Carolina, United States, within portions of Iredell, Wilkes and Yadkin Counties that lie on the Piedmont plateau region. The viticultural area was recognized on May 27, 2008 by the Alcohol and Tobacco Tax and Trade Bureau (TTB), Treasury after reviewing the petition submitted by Raffaldini Vineyards on behalf of the Vineyards of Swan Creek, a trade association representing a group of vineyards and wineries from the locale to establish an appellation named "Swan Creek." The appellation is the state's 2nd AVA encompassing 96,000 acres (150 sq mi) with 75 acres (30 ha) of cultivation. The northern 60 percent of the Swan Creek AVA sits within the Yadkin Valley viticultural area, and the remaining 40 percent extends outside of the Yadkin Valley AVA southern boundary. Swan Lake AVA encircles the townships of Hamptonville, Harmony, Mooresville, Ronda, Wilkesboro and Yadkinville. The AVA shares its name with the unincorporated community of Swan Creek in Yadkin County.
The Rocks District of Milton-Freewater is an American Viticultural Area (AVA) in Umatilla County, Oregon that is a sub-appellation of the Walla Walla Valley AVA, and both lie within the vast Columbia Valley AVA. The appellation was established on March 11, 2015 by the Alcohol and Tobacco Tax and Trade Bureau (TTB), Treasury after reviewing the petition submitted from Dr. Kevin R. Pogue, a professor of geology at Whitman College in Walla Walla, Washington, proposing the viticultural area called "The Rocks District of Milton-Freewater."
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), Treasury 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. The term "SLO" is a historical and commonly used reference for the county and city initials as well as a description of the region's relaxed culture. The new AVA overlaps the previously established Edna Valley and Arroyo Grande Valley viticultural areas. There are over 50 wineries and an estimated 78 commercial vineyards cultivating approximately 3,942 acres (1,595 ha) with a majority of the vineyards located within 6 miles (9.7 km) of the Pacific Ocean defining an area whose grapes and wines represent it. Cool weather varietals like Pinot Noir and Chardonnay are commonly grown while lesser varietals Sauvignon Blanc, Gewürztraminer and Gruner Veltliner also thrive.
