Input (English): Context: The Northern Sonoma AVA is an American Viticultural Area in Sonoma County , California , USA . 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 ., An American Viticultural Area (AVA) is a designated wine grape-growing region in the United States distinguishable by geographic features, with boundaries defined by the Alcohol and Tobacco Tax and Trade Bureau (TTB) of the United States Department of the Treasury., Pinot noir is a red wine grape variety of the species "Vitis vinifera". The name may also refer to wines created predominantly from Pinot noir grapes. The name is derived from the French words for "pine" and "black"; the "pine" alluding to the grape variety having tightly clustered, pine cone-shaped bunches of fruit., Los Carneros AVA (also known as Carneros AVA) is an American Viticultural Area which includes parts of both Sonoma and Napa counties in California, U.S.A.. It is located north of San Pablo Bay. The proximity to the cool fog and breezes from the bay makes the climate in Los Carneros cooler and more moderate than the wine regions further north in Napa Valley and Sonoma Valley. The cooler climate has made Los Carneros attractive for the cultivation of cooler climate varietals like Pinot noir and Chardonnay. Many of the grapes grown in Los Carneros are used for sparkling wine production. Receiving its AVA status in 1983, the Carneros area was the first wine region in California to be defined by its climate characteristics rather than political boundaries., The Alcohol and Tobacco Tax and Trade Bureau, statutorily named the Tax and Trade Bureau and frequently shortened to TTB, is a bureau of the United States Department of the Treasury., California is the most populous state in the United States and the third most extensive by area. Located on the western (Pacific Ocean) coast of the U.S., California is bordered by the other U.S. states of Oregon, Nevada, and Arizona and shares an international border with the Mexican state of Baja California. The state capital is Sacramento. Los Angeles is California's most populous city, and the country's second largest after New York City. The state also has the nation's most populous county, Los Angeles County, and its largest county by area, San Bernardino County., Chardonnay is a green-skinned grape variety used in the production of white wine. The variety originated in the Burgundy wine region of eastern France, but is now grown wherever wine is produced, from England to New Zealand. For new and developing wine regions, growing Chardonnay is seen as a "rite of passage" and an easy entry into the international wine market., Sonoma Valley is located in southeastern Sonoma County, California, in the San Francisco Bay Area. Known as the birthplace of the California wine industry, the valley is home to some of the earliest vineyards and wineries in the state, some of which survived the phylloxera epidemic of the 1870s and the impact of prohibition in the early 20th century. Today, the valley's wines are protected by the US Federal Government's Sonoma Valley and Carneros AVAs (or American Viticultural Areas)., Sparkling wine is a wine (usually white) that becomes carbonated, either through fermentation or by addition of carbon dioxide. The oldest known production of sparkling wine took place in 1531 with the "ancestral method". Champagne is the most well-known variant, but there are other variations such as Spanish Cava, Italian Spumante, Crémant from France and Sekt from Germany., Sparkling wine is a wine with significant levels of carbon dioxide in it, making it fizzy. The best known example of a sparkling wine is champagne, which is exclusively produced in the Champagne region of France. Most sparkling wine is white or rosé but there are examples of red sparkling wines such as the Italian Brachetto, Australian sparkling Shiraz, and Azerbaijani "Pearl of Azerbaijan" made from Madrasa grapes. The sweetness of sparkling wine can range from very dry "brut" styles to sweeter "doux" varieties (from the French words for 'raw' and 'sweet', respectively)., A varietal wine is a wine made primarily from a single named grape variety, and which typically displays the name of that variety on the wine label. Examples of grape varieties commonly used in varietal wines are Cabernet Sauvignon, Chardonnay and Merlot. Wines that display the name of two or more varieties on their label, such as a Chardonnay-Viognier, are blends and not varietal wines. The term is frequently misused in place of vine variety; the term variety refers to the vine or grape while varietal refers to the wine produced by a variety., The Sonoma Valley AVA is an American Viticultural Area in Sonoma County, California, United States which centers on the Sonoma Valley (also known as "The Valley of the Moon") in the southern portion of the county. The appellation is bordered by two mountain ranges: the Mayacamas Mountains to the east and the Sonoma Mountains to the west., Nevada (Spanish for "snowy"; see pronunciations) is a state in the Western, Mountain West, and Southwestern regions of the United States of America. Nevada is the 7th most extensive, the 34th most populous, and the 9th least densely populated of the 50 United States. Nearly three-quarters of Nevada's people live in Clark County, which contains the Las VegasParadise metropolitan area where three of the state's four largest incorporated cities are located. Nevada's capital is Carson City. Nevada is officially known as the "Silver State" because of the importance of silver to its history and economy. It is also known as the "Battle Born State", because it achieved statehood during the Civil War (the words "Battle Born" also appear on the state flag); as the "Sage-brush State", for the native plant of the same name; and as the "Sage-hen State". Nevada borders Oregon to the northwest, Idaho to the northeast, California to the west, Arizona to the southeast and Utah to the east., Wine (from Latin "vinum") is an alcoholic beverage made from fermented grapes. These grapes are generally "Vitis vinifera," or a hybrid with "Vitis labrusca" or "Vitis rupestris". Grapes are fermented without the addition of sugars, acids, enzymes, water, or other nutrients. Yeast consumes the sugar in the grapes and converts it to ethanol and carbon dioxide. Different varieties of grapes and strains of yeasts produce different styles of wine. These variations result from the complex interactions between the biochemical development of the grape, the reactions involved in fermentation, the terroir, and the production process. Many countries enact legal appellations intended to define styles and qualities of wine. These typically restrict the geographical origin and permitted varieties of grapes, as well as other aspects of wine production., An appellation is a legally defined and protected geographical indication used to identify where the grapes for a wine were grown; other types of food often have appellations as well. Restrictions other than geographical boundaries, such as what grapes may be grown, maximum grape yields, alcohol level, and other quality factors, may also apply before an appellation name may legally appear on a wine bottle label. The rules that govern appellations are dependent on the country in which the wine was produced., Subject: northern sonoma ava, Relation: product, Options: (A) cabernet sauvignon (B) chardonnay (C) food (D) merlot (E) pinot noir (F) red wine (G) silver (H) sugars (I) tobacco (J) wine
