The wine region within the historical province of Champagne in the northeast of France is best known for the production of champagne, the sparkling white wine that bears the region's name. EU law and the laws of most countries reserve the term "champagne" exclusively for wines that come from this region located about 160 kilometres (100 miles) east of Paris. The viticultural boundaries of Champagne are legally defined and split into five wine-producing districts within the historical province: Aube, Côte des Blancs, Côte de Sézanne, Montagne de Reims, and Vallée de la Marne. The city of Reims and the town of Épernay are the commercial centers of the area. Reims is famous for its cathedral, the venue of the coronation of the French kings and a UNESCO World Heritage Site.

Located at the northern edges of France, the history of the Champagne wine region has had a significant role in the development of this unique terroir. The area's proximity to Paris promoted the region's economic success in its wine trade but also put the villages and vineyards in the path of marching armies on their way to the French capital. Despite the frequency of these military conflicts, the region developed a reputation for quality wine production in the early Middle Ages and was able to continue that reputation as the region's producers began making sparkling wine with the advent of the great champagne houses in the 17th and 18th centuries. The principal grapes grown in the region include Chardonnay, Pinot noir, and Pinot Meunier. Pinot noir is the most widely planted grape in the Aube region and grows very well in Montagne de Reims. Pinot Meunier is the dominant grape in the Vallée de la Marne region. The Côte des Blancs is dedicated almost exclusively to Chardonnay.K. Gargett, P. Forrestal, & C. Fallis (2004).

The unique, chalky landscape of the Champagne wine region and the resulting agro-industrial system led to the development of sparkling wines like champagne in the 17th century. As a result, many of the production sites and wine houses in the region were inscribed on the UNESCO World Heritage List in 2015 as part of the Champagne hillsides, houses and cellars site.

Geography and climate

The Champagne province is located near the northern limits of the wine world along the 49th parallel. The high latitude and mean annual temperature of 10 °C (50 °F) creates a difficult environment for wine grapes to fully ripen. Ripening is aided by the presence of forests which helps to stabilize temperatures and maintain moisture in the soil. The cool temperatures serve to produce high levels of acidity in the resulting grape which is ideal for sparkling wine.K. Gargett, P. Forrestal, & C. Fallis The Encyclopedic Atlas of Wine pg 163 Global Book Publishing 2004

During the growing season, the mean July temperature is 18 °C (66 °F). The average annual rainfall is 630 mm (25 inches), with 45 mm (1.8 inches) falling during the harvest month of September. Throughout the year, growers must be mindful of the hazards of fungal disease and early spring frost.H. Johnson & J. Robinson The World Atlas of Wine pg 79 Octopus Publishing Group 2005

Ancient oceans left behind chalk subsoil deposits when they receded 70 million years ago. Earthquakes that rocked the region over 10 million years ago pushed the marine sediments of belemnite fossils up to the surface to create the belemnite chalk terrain. The belemnite in the soil allows it to absorb heat from the sun and gradually release it during the night as well as providing good drainage. This soil contributes to the lightness and finesse that is characteristic of Champagne wine. The Aube area is an exception with predominately clay based soil. The chalk is also used in the construction of underground cellars that can keep the wines cool through the bottle maturation process.

History

The Carolingian reign saw periods of prosperity for the Champagne region beginning with Charlemagne's encouragement for the area to start planting vines and continuing with the coronation of his son Louis the Pious at Reims. The tradition of crowning kings at Reims contributed to the reputation of the wines that came from this area.R. Phillips A Short History of Wine pg 75 HarperCollins 2000 The Counts of Champagne ruled the area as an independent county from 950 to 1316. In 1314, the last Count of Champagne assumed the throne as King Louis X of France and the region became part of the Crown territories.

Military conflicts The location of Champagne played a large role in its historical prominence as it served as a "crossroads" for both military and trade routes. This also made the area open to devastation and destruction during military conflicts that were frequently waged in the area. In 451 A.D. near Châlons-en-Champagne, Attila and the Huns were defeated by an alliance of Roman legions, Franks and Visigoths. This defeat was a turning point in the Huns' invasion of Europe.H. Johnson Vintage: The Story of Wine pg 96–97 Simon & Schuster 1989

During the Hundred Years' War, the land was repeatedly ravaged and devastated by battles. The Abbey of Hautvillers, including its vineyards, was destroyed in 1560 during the War of Religion between the Huguenots and Catholics. This was followed by conflicts during the Thirty Year War and the Fronde Civil War where soldiers and mercenaries held the area in occupation. It was not until the 1660s, during the reign of Louis XIV, that the region saw enough peace to allow advances in sparkling wine production to take place.H. Johnson Vintage: The Story of Wine pg 210–211 Simon & Schuster 1989

History of wine production

The region's reputation for wine production dates back to the Middle Ages when Pope Urban II ( ruled 1088-1099 AD/CE ), a native Champenois, declared that the wine of Aÿ in the Marne département was the best wine produced in the world. For a time Aÿ was used as a shorthand designation for wines from the entire Champagne region, similar to the use of Beaune for the wines of Burgundy.H. Johnson Vintage: The Story of Wine pg 211 Simon & Schuster 1989 The poet Henry d'Andeli's work La Bataille des Vins rated wines from the towns of Épernay, Hautvillers and Reims as some of the best in Europe. As the region's reputation grew, popes and royalty sought to own pieces of the land with Pope Leo X, Francis I of France, Charles V of Spain, and Henry VIII of England all owning vineyard land in the region. A batch of wine from Aÿ received in 1518 by Henry VIII's chancellor, Cardinal Thomas Wolsey, is the first recorded export of wine from the Champagne region to England.K. Gargett, P. Forrestal, & C. Fallis The Encyclopedic Atlas of Wine pg 162 Global Book Publishing 2004

The still wines of the area were highly prized in Paris under the designation of vins de la rivière and vins de la montagne- wines of the river and wines of the mountain in reference to the wooded terrain and the river Marne which carried the wines down to the Seine and into Paris.H. Johnson & J. Robinson The World Atlas of Wine pg 80 Octopus Publishing Group 2005 The region was in competition with Burgundy for the Flemish wine trade and tried to capitalize on Reims' location along the trade route from Beaune. In the 15th century, Pinot noir became heavily planted in the area. The resulting red wine had difficulty comparing well to the richness and coloring of Burgundy wines, despite the addition of elderberries to deepen the color. This led to a greater focus on white wines.H. Johnson Vintage: The Story of Wine pg 212 Simon & Schuster 1989

The Champagne house of Gosset was founded as a still wine producer in 1584 and is the oldest Champagne house still in operation today. Ruinart was founded in 1729 and was soon followed by Chanoine Frères (1730), Taittinger (1734), Moët et Chandon (1743) and Veuve Clicquot (1772).

The nineteenth century saw an explosive growth in Champagne production going from a regional production of 300,000 bottles a year in 1800 to 20 million bottles in 1850.R. Phillips A Short History of Wine pg 241 HarperCollins 2000

Rivalry with Burgundy A strong influence on Champagne wine production was the centuries-old rivalry between the region and Burgundy. From the key market of Paris to the palace of Louis XIV at Versailles, proponents of Champagne and Burgundy would compete for dominance. For most of his life, Louis XIV would drink only Champagne wine with the support of his doctor Antoine d'Aquin who advocated the King drink Champagne with every meal for the benefit of his health. As the King aged and his ailments increased, competing doctors would propose alternative treatments with alternative wines, to soothe the King's ills. One of these doctors, Guy-Crescent Fagon conspired with the King's mistress to oust d'Aquin and have himself appointed as Royal Doctor. Fagon quickly attributed the King's continuing ailments to Champagne and ordered that only Burgundy wine must be served at the royal table.D. & P. Kladstrup Champagne pg 32 HarperCollins Publishers

This development had a ripple effect throughout both regions and in the Paris markets. Both Champagne and Burgundy were deeply concerned with the "healthiness" reputation of their wines, even to the extent of paying medical students to write theses touting the health benefit of their wines. These theses were then used as advertising pamphlets that were sent to merchants and customers. The Faculty of Medicine in Reims published several papers to refute Fagon's claim that Burgundy wine was healthier than Champagne. In response, Burgundian winemakers hired physician Jean-Baptiste de Salins, dean of the medical school in Beaune, to speak to a packed auditorium at the Paris Faculty of Medicine. Salins spoke favorably of Burgundy wine's deep color and robust nature and compared it to the pale red color of Champagne and the "instability" of the wine to travel long distances and the flaws of the bubbles from when secondary fermentation would take place. The text of his speech was published in newspapers and pamphlets throughout France and had a damaging effect on Champagne sales.D. & P. Kladstrup Champagne pg 33–34 HarperCollins Publishers

The war of words would continue for another 130 years with endless commentary from doctors, poets, playwrights and authors all arguing for their favorite region and their polemics being reproduced in advertisements for Burgundy and Champagne. On a few occasions, the two regions were on the brink of civil war.D. & P. Kladstrup Champagne pg 36 HarperCollins Publishers A turning point occurred when several Champagne wine makers abandoned efforts to produce red wine in favor of focusing on harnessing the effervescent nature of sparkling Champagne. As the bubbles became more popular, doctors throughout France and Europe commented on the health benefits of the sparkling bubbles which were said to cure malaria. As more Champenois winemakers embarked on this new and completely different wine style, the rivalry with Burgundy mellowed and eventually waned.

Classifications and vineyard regulations

In 1927, viticultural boundaries of Champagne were legally defined and split into five wine-producing districts: The Aube, Côte des Blancs, Côte de Sézanne, Montagne de Reims, and Vallée de la Marne. This area covered in 2008 33,500 hectares (84,000 acres) of vineyards around 319 villages that were home to 5,000 growers who made their own wine and 14,000 growers who only sold grapes.
