Introduction

Champagne is often drunk as part of a celebrationChampagne is a sparkling wine produced by inducing the secondary fermentation of wine. It is named after the Champagne region of France . While the term "champagne" is often used by makers of sparkling wine in other parts of the world, such as California and Canada , it should properly be used to refer only to the wines made in the region of Champagne , France . The community, under the auspices of the Comité Interprofessionel du Vin de Champagne has developed a comprehensive set of rules and regulations for all wine that comes from the region. These rules are designed to ensure that the highest quality product is produced and include a codification of the most suitable places for grapes to grow, the most suitable types of grapes – most Champagne is produced from one or a blend of up to three varieties of grapes: chardonnay, pinot noir, and pinot meunier (although five other varietals are permitted) – and has identified a lengthy set of requirements that specify most aspects of viticulture. This includes vine pruning, the yield of the vineyard, the degree of pressing applied to the grapes, and the time that bottles must remain on the lees. Only if a wine meets all these requirements may the name Champagne be placed on the bottle. The rules that have been agreed upon by the CIVC are then presented to the INAO for final approval.

In Europe and most other countries, the name "champagne" is legally protected as part of the Treaty of Madrid (1891) to mean only sparkling wine produced in its namesake region and adhering to the standards defined for that name as an Appellation d'Origine Contrôlée. This right was reaffirmed in the Treaty of Versailles following World War I. Even the term méthode champenoise, or champagne method is, as of 2005, forbidden in favor of méthode traditionelle. There are sparkling wines made all over the world, and many use special terms to define their own sparkling wines: Spain uses Cava , Italy calls it spumante, and South Africa uses Cap Classique. A sparkling wine made from Muscat grapes in Italy uses the DOCG Asti. In Germany , Sekt is a common sparkling wine. Even other regions of France are forbidden to use the name Champagne ; for example, wine-makers in Burgundy and Alsace produce Crémant.

Other sparkling wines not from Champagne sometimes use the term "sparkling wine" prominently on their label. While most countries have labeling laws that protect wine producing locations such as Champagne , some – including the United States – continue to allow U.S. wine producers to utilize the name “ Champagne ” on the label of products that do not come from Champagne . To allow this practice, the U.S. Congress passed a law claiming that the term "champagne" is semi-generic. This often leads to consumer confusion about genuine Champagne and is seen as deceptive by some consumers and wine experts. While some U.S. companies ironically claim that their long usage of the term prevents them from dropping the word champagne on the bottle, many quality U.S. sparkling wine makers have ceased use of the term, instead favoring "sparkling wine" as their identifier.

Champagne 's sugar content varies. The sweetest level is doux (meaning sweet), proceeding in order of increasing dryness to demi-sec (half-dry), sec (dry), extra sec (extra dry), brut (almost completely dry), and extra brut / brut nature / brut zero (no additional sugar, sometimes ferociously dry.).

Method of Production
Grapes used for Champagne are generally picked earlier, when sugar levels are lower and acid levels higher. Except for pink or rosé Champagnes , the juice of harvested grapes is pressed off quickly, to keep the wine white. The traditional method of making Champagne is known as the Méthode Champenoise.

The first fermentation begins in the same way as any wine, converting the natural sugar in the grapes into alcohol while the resultant carbon dioxide is allowed to escape. This produces the "base wine". This wine is not very pleasurable by itself, being too acidic. At this point the blend is assembled, using wines from various vineyards, and, in the case of non-vintage Champagne , various years.

The blended wine is put in bottles along with yeast and a small amount of sugar, called the liqueur de tirage, and stored in a wine cellar horizontally, for a second fermentation. During the secondary fermentation the carbon dioxide is trapped in the bottle, keeping it dissolved in the wine. The amount of added sugar will determine the pressure of the bottle. To reach the standard value of 6 bars inside the bottle is necessary to have 18 grams of sugar, and the amount of yeast, Saccharomyces cerevisiae, is regulated by the European Commission (Regulation 1622/2000, 24 July 2000 ) to be 0.3 grams per bottle. The "liqueur de tirage" is then a mixture of sugar, yeast and still champagne wine.

Champagne CapsulesAfter ageing (a mimimum from one and a half to three years), they undergo a process known as riddling (remuage in French), in which they are rotated a small amount each day and gradually moved to a neck-down orientation, so that the sediment ('lees') collects in their necks and can be removed. The removal process is called "disgorging" (dégorgement in French), and was a skilled manual process, where the cork and the lees were removed without losing large quantities of the liquid, and a dosage (a varying amount of additional sugar) is added. Until this process was invented (reputedly by Madame Clicquot in 1800) Champagne was cloudy, a style still seen occasionally today under the label méthode ancestrale. Modern disgorgement is automated by freezing a small amount of the liquid in the neck and removing this plug of ice containing the lees. A cork is then inserted with a capsule and wire cage securing it in place.

Wines from Champagne cannot legally be sold until it has aged on the lees in the bottle for at least 18 months. Champagne 's AOC regulations require that vintage Champagnes are aged in cellars for three years or more before disgorgement, but most top producers exceed this minimum requirement, holding bottles on the lees for 6 to 8 years before disgorgement.

Even experts disagree about the effects of aging on Champagne after disgorgement. Some prefer the freshness and vitality of young, recently disgorged Champagne , and others prefer the baked apple and caramel flavors that develop from a year or more of aging.

The majority of the Champagne produced is non-vintage (also known as mixed vintage), a blend of wines from several years. Typically the majority of the wine is from the current year but a percentage is made of "reserve wine" from previous years. This serves to smooth out some of the vintage variations caused by the marginal growing climate in Champagne . Most Champagne houses strive for a consistent "house style" from year to year, and this is the hardest task of the winemaker.

The grapes to produce vintage Champagne must be 100% from the year indicated (other sparkling wines in the EU need only be 85% to be called vintage). To maintain the quality of non-vintage champagne a maximum of half the grapes harvested in one year can be used in the production of vintage Champagne ensuring at least 50%, though usually more, is reserved for non-vintage wines. Vintage Champagnes are the product of a single high-quality year, and bottles from prestigious makers can be rare and expensive.

Champagne Varieties
A 1952 poster advertising Soviet champagne.Champagne is a single Appellation d'Origine Contrôlée. Grapes must be the white Chardonnay, or the red Pinot Noir or Pinot Meunier (a few very rare other grapes that were historically important are allowed, but very unusual). Champagnes made exclusively from Chardonnay are known as blanc de blancs, and those exclusively from the red grapes as blanc de noirs. Champagne is typically a white wine even if it is produced with red grapes, because the juice is extracted from the grapes using a gentle process that minimizes the amount of time the juice spends in contact with the skins, which is what makes red wine red. Rosé wines are also produced, either by permitting the juice to spend more time with the skins to impart a pink color to the wine, or by adding a small amount of red wine during blending. The amount of sugar (dosage) added after the second fermentation and ageing also varies, from brut zéro or brut natural, where none is added, through brut, extra-dry, sec, demi-sec and doux. The most common is brut, although in the early 20th century Champagne was generally much sweeter.

Most Champagne is non-vintage, produced from a blend of years (the exact blend is only mentioned on the label by a few growers), while that produced from a single vintage is labelled with the year and Millésimé.

Many Champagnes are produced from bought-in grapes by well known brands such as Veuve Clicquot or Mumm.

Origins
Wines from the Champagne region were already known before medieval times. Churches owned vineyards, and monks produced wine for use in the sacrament of Eucharist. French kings were traditionally anointed in Reims . Champagne wine flowed as part of coronation festivities.

Kings appreciated the still, light, and crisp wine, and offered it as an homage to other monarchs in Europe . In the 17th century, still wines of Champagne were the chosen wines for celebration in European countries. English people were the biggest consumers of Champagne wines, and drank a lot of sparkling wines.

The first commercial sparkling wine was produced in the Limoux area of Languedoc about 1535. They did not invent it; nobody knows who first made it, although the British make a reasonably good claim. Contrary to legend and popular belief, the French monk Dom Perignon did not invent champagne, although it is almost certainly true that he developed many advances in the production of this beverage.

Somewhere in the end of the 17th century, the sparkling method was imported in the Champagne region, associated with specific procedures for production (smooth pressing, dosage...), and stronger bottles (invented in England ) that could hold the added pressure. Around 1700, sparkling Champagne was born.

The leading manufacturers devoted considerable energy to creating a history and identity for their wine, associating it and themselves with nobility and royalty. Through advertising and packaging they persuaded the world to turn to champagne for festivities and rites de passage and to enjoy it as a luxury and form of conspicuous consumption. Their efforts coincided with an emerging middle class that was looking for ways to spend its money on symbols of upward mobility.

English people loved the new sparkling wine, and spread it all over the world. Brut Champagne , the modern Champagne , was created for the British in 1876. The Russian royalty also consumed huge quantities, preferring the sweeter styles.

The Comité Interprofessional du Vin de Champagne
All of the over 15,000 growers, cooperatives and over 300 houses that are central to producing Champagne are members of the Comité Interprofessional du Vin de Champagne (CIVC). This organization has a system where both the houses and the growers are represented at all levels. This includes a co-presidency where a grower representative and a representative of the houses share the running of the organization. This system is designed to ensure that the CIVC's primary mission -- to promote and protect Champagne -- is done in a manner that represents the consensus of the community. This power structure has played an important role in the success of Champagne worldwide and the integrity of the appellation itself.

Champagne bottles
Side-by-side comparison of champagne bottles. (L to R) On ladder: magnum, full, half, quarter. On floor: Balthazar, Salmanazar, Methuselah, JeroboamChampagne is mostly fermented in two sizes bottles, standard bottle (750 mL), and Magnum (1.5 L). In general, magnums are thought to be higher quality, as there is less oxygen in the

List of bottle sizes:

• quarter bottle (aka. split or piccolo bottle) (187.5 or 200 ml)
• mainly used by airlines, hotel mini-bars and nightclubs.
• half-bottle (aka. Demi) (375 ml)
• used in restaurants
• bottle (aka. Imperial) (750 ml)
• Magnum (1.5 L) (equivalent to 2 bottles)
• Jeroboam (3 L) (4 bottles)
• Rehoboam (4.5 L) (6 bottles)
• Methuselah (6 L) (8 bottles)
• Salmanazar (9 L) (12 bottles)
• Balthazar (12 L) (16 bottles)
• Nebuchadnezzar (15 L) (20 bottles)
• Melchior (18 L) (24 bottles)
• Solomon (25 L)
• Primat (27 L) (36 bottles)
• Melchizedek (30 L) (40 bottles)

Sizes larger than Jeroboam are rare. Primat sized bottles - and as of 2002 Melchizedek sized bottles - are exclusively offered by the House Drappier. The same names are used for bottles containing wine and port; however Jeroboam, Rehoboam and Methuselah refer to different bottle volumes. On occasion unique sizes have been made for special occasions and people. The most notable example perhaps being the 20 fluid ounce/ 60cl. bottle (Imperial pint) made specially for Sir Winston Churchill by Pol Roger. This was served to Mr Churchill by his butler at 11am as he was getting up.

Opening Champagne bottles
Champagne corksThe deliberate spraying of Champagne has become an integral part of sports trophy presentations and locker room celebrations, though Champagne enthusiasts sometimes cringe at the waste. To reduce the risk of spilling Champagne and/or turning the cork into a projectile, open a Champagne bottle as follows:

• Remove the foil and pull down the wire loop;
• Drape a towel over the bottle:
• Place your hand over the cork;
• Loosen but don't remove the wire cage;
• Grasp the cork and the cage firmly with your hand, then rotate the bottle (rather than the cork) by holding it at the base; this should allow the cork to come out on its own accord.

The desired effect is to ease the cork out with a sigh or a whisper rather than a pop or to shoot the cork across the room or produce a fountain of foamy wine. Most wine connoisseurs insist that the ideal way to open a bottle of Champagne is to do it so carefully and gently that very little sound is emitted at all.

Sabrage
A sabre can be used to open a Champagne bottle with great ceremony. This technique is called sabrage. The sabre is slid along the body of the bottle toward the neck. The force of the blade hitting the lip separates the lip from the neck of the bottle. The cork and lip remain together after separating from the neck. Sabrage does not involve a slicing motion. To properly execute, one should:

• Select a heavy sabre, with a rather short blade and broad back;
• Hold in one hand the sabre. Use the back and not the cut of the blade;
• Hold in the other hand the Champagne bottle on its lowest part, the wire cage loosened or removed;
• Touch and slide the blade alongside the bottle until it hits the swelling on the bottleneck. The jolt will break the bottle and its tip will fly away in a trajectory;
• Have part of the spray spill out in order to wash away potential glass splinters;

Using the sabre method is not particularly difficult, but some precautions are necessary:

• The sabre is a weapon and might be dangerous;
• The tip of the bottle will fly away with force. Keep the foreseen trajectory free of obstacles;
• Check fluid for glass splinters before drinking;
• Don't touch the top of the bottle after opening, it's likely to have razor sharp edges

Serving Champagne

Champagne is usually served in a champagne flute, whose characteristics include a long stem with a tall, narrow bowl and opening. The wider flat glass (cup) commonly associated with Champagne is no longer preferred by connoisseurs because it does not preserve the bubbles and aroma of the wine as well.

Champagne Fountain serving 10 Gallons of ChampagneBut Champagne is better for tasting with a big red wine glass (i.e. a glass for bordeaux), as the aroma spreads better in the large area of the glass, but contrary to the cup, the aroma stays in the glass.

Don't try to fill the glass: flutes shall be filled only 2/3 of the glass, and big red wine glasses not more than 1/3 of the glass.

Champagne is always served cold, and is best at the temperature 7C° (43 to 48°F). Often the bottle is chilled in a bucket of ice and water before and after opening. Champagne buckets are made specifically for this purpose.
