There are two main methods of making French sparkling wine, the Méthode Champenoise of bottle fermentation, and the closed tank fermentation method, often referred to as Méthode Charmat (from the name of the French scientist who developed it).
Assembling the base wine: The base wine is a blend or cuvée generally made from the varieties Chardonnay and Pinot Noir (in France Pinot Meunier is also used) using early picked grapes to retain high acidity.
Tirage: This wine is then bottled, with the addition of the liqueur de tirage, a syrupy solution that includes cane sugar and selected yeasts.
Re-fermentation: After being sealed with metal caps, bottles are shaken and stacked horizontally in a cellar at a constant temperature. Over the next four to five months the yeasts create a gradual re-fermentation in the wine which transforms the sugar into alcohol, adding one or two degrees to the total alcohol content, and carbon dioxide. At the end of the process the gas will have built up a pressure of 5-6 atmospheres in the bottle.
Ageing on the lees: The wine must now age for approximately another 2 to 3 years. During this period the yeast cells break down in a process known as autolysis, creating sediment in the bottle. Bottles are re-stacked every six months or so to check for breakage and shaken (a practice called coup de poignet in French) to prevent the deposit sticking to the side of the glass.
Riddling: Once ageing is complete, the sediment must be removed from the bottle. The first step is riddling, or remuage, in which bottles are placed top down at a 45-degree angle in the slots of hinged A – frame racks known as pupitres. Over the next two months each bottle is skillfully twisted by hand an eighth of its circumference per day to work the deposit down to the neck. The bottles are gradually up-ended in the pupitres until they stand upright in the slots and the deposit rests against the cap.
Removing the sediment: The next step is the dégorgement. This involves freezing the deposit by inserting the neck of the inverted bottle in a chilled saline solution. The cap is then removed and the pressure of carbon dioxide in the bottle forces out the plug of frozen sediment.
Topping: The small amount of wine that is lost during the removal of the sediment must now be replaced. Most types of Champagnes are topped up with a solution of mature wine, sugar and the liqueur d’ expedition, a solution of older wine and cane sugar.Champagne is classified according to its level of residual sugar, using the following terms:Non Dosé: refers to Champagne topped up with the same wine, without sugar. The driest type. Brut: refers to wines with a maximum of 15 g/l of residual sugar. Extra dry: has 12-20 g/l Sec: has 17-35 g/l Demi-sec: has 33-50 g/l Doux: has over 50 g/l
Bottles are then sealed with the familiar mushroom shape cork, which is anchored with wire to withstand the considerable pressure from inside the bottle.
Bottles are stored for a time so that the liqueur becomes amalgamated with the wine. On average it takes about three years to produce a fine, bottle-fermented sparkling wine.
Tank Fermentation: La Méthode Charmat
The process of making sparkling wine in sealed tanks is generally known as Methode Charmat.
Re-fermentation: The base wines blended with selected yeasts and sugar are placed in large, stainless steel tanks where re-fermentation takes place at a temperature of 120-130C under pressure of around 7-8 atmospheres.
Isobaric filtration: When re-fermentation is complete, the wine is separated from the lees by passing through a filter unto another tank under equal pressure.
Stabilization:: The wine is stabilized by being chilled to – 40C. This causes tartaric acid to precipitate in the form of crystals, which are then removed.
Isobaric bottling: The isobaric principle is used to maintain constant pressure in the wine as it is bottled and corked. Wines made by the tank fermentation method are usually released soon after bottling, though some Charmat wines seem to gain harmony after a few months of cellaring.
Do you think you could tell between champagne and other sparkling wines? In any case, you could have a lot of fun trying. Locals say that a good quality sparking wine can be equivalent or better than a mediocre champagne. Beyond the price – a telltale sign for champagne – the easy way to spot the difference is that a sparkling wine can only be named champagne if it comes form the region of Champagne, in Eastern France. It must be produced with the méthode champenoise and can onlybe made mainly using pinot noir (dark skin), meunier (dark skin) andchardonnay grapes (white), and in somecases arbane, le petit meslier,pinot blanc andpinot gris (all white skinned)varieties although theserepresent only a small fraction of the production.

There are two main methods of making French sparkling wine, the Méthode Champenoise of bottle fermentation, and the closed tank fermentation method, often referred to as Méthode Charmat
Méthode Charmat
Charmat method
The method is now named after the latter, but is also called cuve close, metodo Italiano or the tank method. The wine is mixed in a stainless steel pressure tank, together with sugar and yeast. Fermentation occurs in a closed system, so CO 2 cannot directly escape to the atmosphere and dissolves in wine.

To be called Champagne, however, a wine must meet strict criteria; such as coming from this specific region in Northern France and being made using the traditional method. This is typically made from a blend of Chardonnay, Pinot Noir and Meunier.
Sparkling wine is usually made according to the Classical Method (or Champenoise) with re-fermentation in the bottle, or according to the Charmat Method, also known as 'Martinotti', with re-fermentation in an autoclave. Then there is a third way, the traditional yeast method, with natural re-fermentation in the bottle.
The main difference between the Traditional Method and the Charmat Method is the vessel used for secondary fermentation. Traditional Method bubbles go through secondary fermentation in the bottle (ex. Champagne), while in Charmat Method, secondary fermentation occurs in...you guessed it...a tank (ex. Prosecco).
A mixture of yeast, yeast nutrients and sugar (liqueur de tirage) that is added to the wine in the second yeasting, the wine is put in a thick glass bottle and sealed with a bottle cap. The wine bottles are placed in a cool cellar to ferment slowly and to produce alcohol and carbon dioxide.
The 5 Champagne subregions. As of 1927, the Champagne AOC can be split into five legally defined subregions: Montagne de Reims, the Marne Valley, Côtes de Blancs, Côtes de Sézanne and Côtes des Bar.
Méthode champenoise, also know as the traditional method, is a sparkling wine production method whereby wine undergoes a second fermentation process in the bottle to produce carbon dioxide—the engine behind that soft, bubbly mouthfeel in sparkling wine and Champagne.
The Charmat method used for Prosecco involves single fermentation in tank, flowed by a pressurised bottling. By contrast, Champagne is fermented twice with the secondary fermentation conducted in bottle with the addition of yeast and solids that provide the bubbles.”
The méthode ancestrale or ancestral method, is the oldest known method of making sparkling wine. The process goes by many names: rurale, gaillacoise, artisanale, pétillant naturel, and in some appellations, like Montlouis-sur-Loire, pétillant originel.
Prosecco uses the Charmat or tank method, where a secondary fermentation takes place in a pressurized vat. Champagne uses the traditional method where the secondary fermentation takes place in the bottle. The initial fermentation of grape must (juice) does in fact produce carbon dioxide and bubbles.
(Actually, the traditional method is the most expensive of all the methods of producing sparkling wine.) This is because the yeast waste is filtered out in a go, instead of bottle-to-bottle, and the exposition liqueur is also added in bulk.
In this method the wine is fermented in autoclaves. These are large pressurised temperature-controlled tanks which look very similar to large stainless steel silos. They keep carbon dioxide trapped inside. This winemaking method yields fresh, fruity wines, enhanced further by the mainly aromatic grape varieties used.
The Charmat method is a sparkling winemaking process that traps bubbles in wine via carbonation in large steel tanks. This technique is also called metodo Italiano, the Marinotti method, the tank method, or cuve close (“sealed tank,” from the French cuvée, or vat).
Secondary Fermentation: Asti is produced using the Charmat-Martinotti method, similar to Prosecco. The base wine is transferred to a large, sealed, pressurized stainless steel tank known as an autoclave. A carefully selected strain of yeast is introduced, initiating the secondary fermentation.
The easy and short answer is that sparkling wine can only be called “Champagne” if it is made in the region of Champagne, France which is located just outside of Paris. To clarify, all Champagne is sparkling wine, but not all sparkling wine is Champagne.
In order for sparkling wine to be classified as champagne, it must be made and bottled in the Champagne region of France, which lies east of Paris. What makes this particular region nestled in the country's northeastern corner so special? In short, everything.
The easy and short answer is that sparkling wine can only be called champagne if it comes from the Champagne region in northern France, just outside of Paris. There are several types of sparkling wine; the most common are champagne, prosecco from Italy, cava from Spain and sparkling wine from Australia.
Although most people think that Champagne wines are made solely from three main grape varieties (Chardonnay, Pinot Noir and Meunier), that's not quite true! Four other varieties are also authorised within the AOC area and are used to make some: Arbane, Petit Meslier, Pinot Blanc and Pinot Gris.
