Ramona Valley is an American Viticultural Area (AVA) in San Diego County, California, centered around the unincorporated town of Ramona. It was the 162nd AVA established on December 7, 2005 by the Alcohol and Tobacco Tax and Trade Bureau (TTB), Treasury after reviewing the petition submitted by the Ramona Vineyard Association, currently the Ramona Valley Vineyard Association (RVVA), proposing to establish a viticultural area in central San Diego County named "Ramona Valley." [6]
The viticultural area surrounding Ramona is located 28 mi (45 km) northeast of San Diego and lies entirely within the vast 3,251,042 acres (5,080 sq mi) multi-county South Coast AVA. It also is south of the two previously established viticultural areas within South Coast, Temecula Valley and San Pasqual Valley. The AVA encircles approximately 89,000 acres (139 sq mi) in a 14.5 by 9.5 miles (23.3 by 15.3 km) west-southwest to east-northeast oriented rectangular area. Ramona Valley is geographically a broad, flat valley surrounded by hills and mountains that isolates it from adjacent areas. The valley has an average vineyard elevation of 1,400 feet (430 m) and an annual average rainfall of 16.5 inches (419.1 mm). In 2005, the area had approximately 17 vineyards cultivating an estimated 45 acres (18 ha) of wine grapes. The petitioners noted the area is known for its distinctive microclimate, elevation, and soil attributes. [1]
Ramona Valley had many agricultural incarnations over the past century, from the "Turkey Capital of the World", dairies, and chicken egg production, to avocados and citrus farms, and currently into a rapidly growing wine grape region. [5] Its viticulture history began with the arrival of Spanish missionaries, led by Junipero Serra, in 1769. American viticulture started as early as 1889, with wine grapes grown at Rancho Bernardo for use at the Bernardo Winery. In modern times, Ross Rizzo, the master vintner at Bernardo Winery, recalls that up to a thousand acres of wine grapes were growing in Ramona Valley during the 1940s and 1950s. The Schwaesdall Winery, which opened in 1993, uses grape vines planted in the Ramona Valley in the 1950s as well as their own plantings begun in 1989. [1]
The distinguishing factors of the Ramona Valley viticultural area include its elevation, which contrasts with the surrounding areas, and climatic factors related to its elevation and inland location. Ramona Valley was the third viticultural area to be designated in the large multi-county South Coast AVA, after San Pasqual Valley in 1981 and Temecula Valley in 1984. In a 2006 interview on National Public Radio, Bill Schweitzer of the Ramona Valley Vineyard Association described the area's exceptional viticultural characteristics as being partially derived from its unique location of being 25 miles (40 km) east of the Pacific Ocean and 25 miles (40 km) west of the Colorado Desert. [7] [2]
Ramona Valley viticultural area is encircled by a ring of hills and mountains that isolate it from the surrounding regions of San Diego County. Santa Maria Creek flows west through the viticultural area before passing through a narrow gap in the hills near the northwestern corner of the area. The lowest elevation of the Ramona Valley viticultural area, 650 ft (200 m), is at the southwest corner of the area at the San Vicente Reservoir. Elevations within the northern, southern, and western portions of the viticultural area vary between 650 and 1,600 feet (200 and 490 m), with an average base elevation of about 1,400 feet (430 m). The eastern terrain of the area rises more than 3,000 feet (910 m) at the foothills of the Cuyamaca Mountains. The highest elevation suitable for viticulture here is 2,640 feet (800 m). Beyond the Ramona Valley viticultural area boundary lines to the south, west, and north are lower coastal valleys with elevations at 500 feet (150 m) or less. While higher in elevation than these coastal valleys, Ramona Valley AVA is significantly lower than the Cuyamaca Mountain Range to the east, which has peaks reaching 6,200 feet (1,900 m). [1]
The Ramona Valley viticultural area has a distinguishable microclimate as compared to the surrounding regions. With the Anza-Borrego Desert 25 mi (40 km) to the east and the Pacific Ocean about 25 mi (40 km) to the west, the desert and ocean influences affect and moderate the Ramona Valley climate during the growing season. Also known locally as "the Valley of the Sun," due to its lack of cool coastal morning fog, Ramona Valley viticultural area is warmer than the lower elevation coastal areas and valleys to its south, west, and north. The area is cooler in the summer, but warmer in the winter, than the higher Cuyamaca Mountains to its east. A comparison of daily temperature variations among the towns of Ramona, Poway, Escondido, and Julian indicates that Ramona has greater daily temperature fluctuations than the surrounding areas. The viticultural area enjoys up to 320 frost-free days and has a heat summation of 3,470 degree-days annually. During the growing season, one degree day accumulates for each degree Fahrenheit that a day’s mean temperature is above 50 degrees, which is the minimum temperature required for grapevine growth. [8] The Ramona Valley viticultural area receives an average annual rainfall of 16.5 inches. This rainfall total is more than that of the lower coastal valleys, but less than the 31 in (790 mm) average received at Julian in the higher mountains to the east of the Ramona Valley area. [1]
Ramona Valley viticultural area has a variety of soil types due to its differing landforms, slopes, and geology. The mountains surrounding the area consist of igneous rock. Also, the mid-slopes to the east and west of the Ramona Valley floor have the reddish coloration of San Marcos Gabbro, a mafic rock type. Mafic rock formations are known to generate nutrient-rich soil, which is ideal for agriculture. Soil series of the Ramona Valley viticultural area include Ramona, Visalia, Los Posas, and Fallbrook loams. The Ramona soil series, as documented in the 1973 U.S. Soil Conservation Service Soil Survey for San Diego County, consists of well-drained, very deep sandy loams with sandy clay loam subsoil. This series is found between the 200 and 1,800 feet (61 and 549 m) elevations on terraces and alluvial fans. [1]
Ramona Valley is often called “The Heart of San Diego’s Wine Country.” Currently, the AVA is home to more than 80 commercial vineyards with over 100 acres (40 ha) of varieties of both white and red grapes in cultivation. As of 2025, there were over 36 bonded wineries operating in the AVA where the Ramona Valley Winery Association labors to establish its identity, discovers its strengths, refining them and building the brand. The area's vineyards and wineries are mostly small boutique, family-owned and operated ventures that adds a personal touch and individualism to the viticulture business resulting in a variety of excellent and award-winning vintages. Yet, Ramona Valley's growing popularity has caught the attention of big wineries building expectations of a future explosion of business and visitors to follow affecting the region for generations to come.

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."
Arroyo Seco is an American Viticultural Area (AVA) in Monterey County, California, southeast of Monterey Bay. The state's 15th appellation was established on May 16,1983 by the Bureau of Alcohol, Tobacco and Firearms (ATF), Treasury after reviewing the petition submitted by the Arroyo Seco Winegrowers and Vintners, an association composed of grape growers and vintners with vineyards, to establish a viticultural area within Monterey County known as "Arroyo Seco."
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".
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 a 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 after reviewing petitions submitted by the Rancho California/Temecula Winegrowers Association and Callaway Vineyard and Winery, Temecula, California in 1981. The petitioners originally proposed to establish a viticultural area in Riverside County to be named "Temecula," "Murrieta," and "Rancho California" but the ATF did not adopt it. In 2004, it was renamed "Temecula Valley" by the Alcohol and Tobacco Tax and Trade Bureau (TTB), approving the 2001 petition submitted by the 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 AVA 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 within Riverside County. County guidelines strictly enforce the number of acres needed to build a winery, lodging and other limited housing and commercial ventures.
North Fork of Roanoke is an American Viticultural Area (AVA) located on the eastern slopes of the Allegheny Mountains in the Roanoke and Montgomery counties of Virginia just west of the city of Roanoke. The appellation area was established by the Treasury's, Bureau of Alcohol, Tobacco and Firearms (ATF) on May 16, 1983. The North Fork valley stretches 22 miles (35 km) along the Roanoke River with surrounding hillsides where vineyards reside between 1,200 to 2,200 feet (366–671 m) above sea level. The approximately 1,200 acres (1.9 sq mi) area is named for its position on the North Fork river, before it converges with the South Fork to form the Roanoke River. Many of North Fork's 49 acres (20 ha) of vineyards are located on the Allegheny slopes which are part of the larger Blue Ridge mountain range that stretches south into North Carolina. The North Fork AVA weather is characterized by cool, foggy summer mornings and prevailing westerly winds. Karl and Myra Hereford of MJC Vineyard in Blacksburg, Virginia, petitioned the ATF in October 1981 to establish the viticulture area named "North Fork of Roanoke.”
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.
San Lucas is an American Viticultural Area (AVA) located in vicinity of the town of San Lucas between King City and San Ardo in southern Monterey County, California. It lies within the southern end of the fertile Salinas Valley. The appellation was recognized on March 7, 1987 by the Bureau of Alcohol, Tobacco and Firearms (ATF), Treasury after reviewing the petition submitted by Almadèn Vineyards of San Jose, California, for the establishment of a viticultural area named "San Lucas." Based on the data submitted by the petitioner for vineyards near King City and San Lucas for the 11-year period 1974 to 1984, ATF concluded that the microclimate of the San Lucas Viticultural Area is the chief characteristic which distinguishes the area from other adjoining areas.
The Spring Mountain District AVA is an American Viticultural Area located in the Napa Valley AVA in California. Spring Mountain District AVA was officially established as an American Viticulture Area in 1993. Encompassed within its bounds are about 8,600 acres (3,480 ha), of which about 1,000 acres (400 ha) are planted to vineyards. Given the small crop yields on hillsides, the region represents less than 2% of Napa Valley wine. Currently the region has just over 30 winegrowers.
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 was established by the Bureau of Alcohol, Tobacco and Firearms (ATF) as the county's first AVA within California’s multi-county Central Coast AVA effective May 12, 1982. 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 designates wine made from grapes grown mostly in Lake County, California. The region is located north of Napa County and east of Mendocino County. Although each region within Lake County has unique viticultural attributes, many are influenced by Clear Lake, the largest inland body of water in California.
Monterey is an American Viticultural Area (AVA) located in eastern Monterey County, California. It was recognized on July 16, 1984 by the Bureau of Alcohol, Tobacco and Firearms (ATF), Treasury after reviewing the petition submitted by the Monterey Winegrowers Council to establish the "Monterey" viticultural area. The designated area within the multi-county Central Coast AVA expands almost the entire length of the county from the Monterey Bay southern shoreline to the Salinas river valley framed by the Santa Lucia, Sierra de Salinas and Gabilan Ranges stretching north-south for about 100 miles (160 km) from Watsonville to its southern point, abutting the town of Paso Robles in San Luis Obispo County. Monterey AVA expands approximately 360,000 acres (560 sq mi) with about 40,000 acres (16,000 ha) of cultivated vineyards. The AVA includes parts of the Carmel and the Salinas valleys containing five smaller American viticultural areas: Arroyo Seco, Hames Valley, San Bernabe, San Lucas and Santa Lucia Highlands. The northern portion is a cool growing region with a very long growing season. Daytime temperatures rarely exceed 75 °F (24 °C) in most parts of the region, although the southern segments of the AVA can measure 100 °F (38 °C) at times. The soil is sandy loam and most regions require irrigation from the Salinas River.
Hames Valley is an American Viticultural Area (AVA) in Monterey County, California a few miles from its southern border with San Luis Obispo (SLO) County. The state's 67th appellation was established on April 15,1994 by the Bureau of Alcohol, Tobacco and Firearms (ATF), Treasury after reviewing the petition submitted by Mr. Barry C. Jackson of the Harmony Wine Company on behalf of Valley Farm Management, Soledad, California, and Mr. Bob Denney & Associates, Visalia, California to establish a viticultural area within Monterey County known as "Hames Valley."
Squaw Valley-Miramonte is an American Viticultural Area (AVA) and a unique grape-growing region in Fresno County, California surrounding the towns of Yokuts Valley and Miramonte approximately 40 miles (64 km) east of the city of Fresno. It was established on August 7, 2015 by the Alcohol and Tobacco Tax and Trade Bureau (TTB), Treasury after reviewing the petition submitted by Christine Flannigan, owner of the Sierra Peaks Winery and Purgatory Vineyards, on behalf of the Squaw Valley Grape Growers Group, proposing the viticulural area named "Squaw Valley-Miramonte." It is largely a rural region located entirely within the foothills of the Sierra Nevada mountains and does not overlap any established AVAs. To the northwest, west, and south is the San Joaquin Valley while the Sequoia National Forest is adjacent to its northern and eastern boundaries. The scenic highway U.S. 180 bisects the region eastward from the Valley to the Big Trees in Kings Canyon and Sequoia National Parks. The AVA stretches over 44,690 acres (70 sq mi) with five commercially-producing vineyards cultivating about 7.5 acres (3.04 ha) and three bonded wineries. The USDA plant hardiness zone for the AVA is 9b.
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.
Monterey County wine is a appellation that designates wine made from grapes grown in Monterey County, California which lies entirely within the expansive multi-county Central Coast viticultural area. 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.
Gabilan Mountains is an American Viticultural Area (AVA) located in the mountainous region on the border in Monterey and San Benito Counties in California. It is the tenth and newest AVA established in Monterey County by the Alcohol and Tobacco Tax and Trade Bureau (TTB) on September 14, 2022, becoming the state's 147th official AVA after the TTB reviewed the petition from Parker Allen of Coastview Vineyards, proposing to establish the "Gabilan Mountains" viticultural area. Gabilan Mountains encompasses about 98,000 acres (153 sq mi) including the established Mt. Harlan and Chalone AVAs, and resident to 4 wineries and 6 commercial vineyards cultivating approximately 436 acres (176 ha). The average elevation within the region is 2,370 feet (722 m) placing it above the heavy fog and marine layer. As a result, Gabilan Mountains AVA has a cool air climate without the humidity from the fog and low-lying clouds.
MountPisgah, Polk County, Oregon is an American Viticultural Area (AVA) in the northern Willamette Valley of Oregon located in Polk County. It was established on June 3, 2022, by the Alcohol and Tobacco Tax and Trade Bureau (TTB), Treasury as the state's 23rd and the 11th appellation in the Willamette Valley viticultural area. It encompasses approximately 5,850 acres (9 sq mi) and contains 10 commercial vineyards cultivating about 648 acres (262 ha) under vine with two wineries. The viticultural area surrounds the 835 ft (255 m) summit of Mount Pisgah among the hills of the Willamette Valley located southwest of Eola Hills, Amity Hills and 15 mi (24 km) from the state capital of Salem. TTB received the petition from the representatives of the local vineyards and wineries proposing a viticultural area named "Mount Pisgah, Polk County, Oregon." It is the southernmost sub-region within the established Willamette Valley viticultural area. The petition notes that vineyard owners plan to expand four of the existing vineyards by a total of 164 acres (66 ha).
San Luis Rey is an American Viticultural Area (AVA) located in San Diego County, California within the vast 3,251,042 acres (5,080 sq mi) multi-county South Coast AVA. The AVA extends from the coastal town of Oceanside inland to the Merriam Mountains and Moosa Canyon. It was established as California's 153rd appellation on August 30, 2024, by the Alcohol and Tobacco Tax and Trade Bureau (TTB), Treasury after reviewing the petition submitted by Rebecca Wood, managing member of Premium Vintners, LLC on behalf of Fallbrook Winery and other local vineyard owners and winemakers proposing the viticultural area named "San Luis Rey." There are 44 commercially-producing vineyards cultivating approximately 256 acres (104 ha), along with 29 acres (12 ha) of planned vineyards and 23 wineries within the AVA. According to the petition, the distinguishing features of San Luis Rey AVA are its topography, climate and soils.
