How Is Champagne Made? – Méthode Traditionnelle Explained
There's a reason Champagne commands such reverence in the wine world. Beyond the prestige and celebration is a production method that is far more meticulous and labour-intensive than you might imagine.
The méthode traditionnelle (also called méthode champenoise) is what separates true Champagne from many other sparkling wines. It's a process that can take years from harvest to glass, involving techniques perfected over centuries. If you're new to Champagne or a little hazy on the process, read on, as we're sure that understanding how Champagne is made will only enhance your appreciation of this incredible product.
Step 1: Harvest and Pressing
Champagne production begins in the vineyards, typically between late August and October – although it's getting earlier all the time! Unlike most wine regions, Champagne mandates hand-harvesting to ensure only the best grapes reach the press.
The pressing must be gentle and swift, particularly for Pinot Noir and Pinot Meunier, which have dark skins that will tint the juice if handled roughly. The goal is to extract clear, pale juice that will become the foundation of the wine.
Only the first pressing or 'cuvée', is considered the highest quality. The subsequent pressing, known as the taille, yields juice with more colour and tannin. Most premium producers use only the cuvée for their finest bottlings.
Step 2: First Fermentation
The freshly pressed juice undergoes its first fermentation, transforming grape sugars into alcohol. This produces a still wine called vin clair. You can taste the wine at this stage and, those with experience and a skilled palate, can often see the direction that the final product will take but, for most, it just tastes thin and acidic.
This is intentional though, as the base wine needs high acidity and relatively low alcohol to develop properly during the second fermentation and ageing process.
Fermentation typically occurs in stainless steel tanks or oak barrels but there are also enamel tanks and concrete eggs, each of which will imbue the wine with unique characteristics.
Step 3: Blending (Assemblage)
Here's where the winemaker's artistry truly shines. Assemblage is the process of blending different base wines to create the final cuvée.
A single Champagne might combine:
-
Multiple grape varieties (Chardonnay, Pinot Noir, Pinot Meunier)
-
Different vineyard plots with distinct soil types and exposures
-
Reserve wines from previous vintages (for non-vintage Champagnes)
For large houses, assemblage ensures consistency, so that their signature style tastes the same year after year. For grower producers, it's often an opportunity to express their unique terroir and vision.
Vintage Champagnes skip the reserve wines entirely, using only grapes from a single exceptional year.
Step 4: Tirage – The Second Fermentation Begins
This is the magic moment. The blended wine is bottled with a precise mixture called liqueur de tirage: wine, sugar, and specially selected yeast. The bottle is sealed with a crown cap (like a beer bottle) or, occasionally with a cork, and then laid horizontally in cool cellars.
Inside each bottle, a second fermentation begins. The yeast consumes the added sugar, producing alcohol and, crucially, carbon dioxide. Because the gas cannot escape, it dissolves into the wine, creating the fine, persistent bubbles that define Champagne.
This process, called 'prise de mousse' (capturing the sparkle), takes about six to eight weeks. But the bottles won't be opened for years yet.
Step 5: Ageing on Lees
After the second fermentation, the spent yeast cells, or 'lees', remain in the bottle. Rather than being a problem, this is essential to the formation of Champagne's character.
As the wine rests on its lees, a process called autolysis occurs. The yeast cells break down, releasing compounds that give Champagne its complexity and depth of flavour, with distinctive notes of brioche, biscuit, and toasted notes. The longer the ageing, the more pronounced these flavours become.
Minimum ageing requirements:
-
Non-vintage Champagne: 15 months (12 months on lees)
-
Vintage Champagne: 3 years
Whilst these are the legal minimum requirements, most quality-focused producers far exceed these minimums. Grower Champagnes often spend 3-5 years on lees for non-vintage cuvées, and prestige bottlings may age for a decade or more.
Step 6: Riddling (Remuage)
After years of ageing, the lees must be removed. But first, they need to be consolidated in the neck of the bottle.
Remuage involves gradually tilting and rotating each bottle over several weeks. Traditionally, this was done by hand using wooden racks called pupitres – a skilled riddler could turn up to 40,000 bottles per day! Today, most producers with large volume use automated gyropalettes that accomplish the same result more efficiently but we work with plenty of small producers who riddle all of their bottles by hand.
By the end of riddling, each bottle sits nearly upside-down with all the sediment collected in the neck, ready for removal.
Step 7: Disgorgement (Dégorgement)
With the sediment in place, it's time for dégorgement. The neck of the bottle is plunged into a freezing solution, forming an ice plug that traps the lees.
When the crown cap is removed, the pressure inside the bottle expels the frozen plug and all the sediment, in a single, satisfying pop. You may have seen videos of vignerons doing this manually with a single bottle to sample or showcase a new release yet to be disgorged.
Many producers note the disgorgement date on their labels, which can be useful for understanding how long the wine has been 'off lees' and further aged within bottle.
Step 8: Dosage
The expelled liquid must be replaced, and this is where dosage comes in. A mixture of wine and sugar called liqueur d'expédition is added to top up the bottle and determine the final level of sweetness.
The amount of sugar added creates the familiar categories: Brut Nature (no sugar), Extra Brut, Brut, Extra Dry, and so on. This final adjustment balances the wine's natural acidity and shapes its character and ageing potential.
Step 9: Corking and Resting
Finally, the bottle receives its iconic mushroom-shaped cork, secured with a wire cage called a muselet. The wine then typically rests for several more months to allow the dosage to integrate before release.
The Grower Champagne difference...
Understanding the méthode traditionnelle reveals why grower Champagnes stand apart. When a single family controls every step – from pruning vines to deciding disgorgement dates – the result is deeply personal. Whilst large houses may produce millions of bottles annually, relying on purchased grapes and industrial efficiency, Grower producers typically make far fewer bottles, with intimate knowledge of every parcel and vintage.
This hands-on approach means longer lees ageing, more thoughtful blending decisions, and wines that genuinely reflect their origins.
Frequently Asked Questions About How Champagne Is Made
What makes Champagne different from other sparkling wines?
Champagne must be made in the Champagne region of France using the méthode traditionnelle. The combination of specific terroir, permitted grape varieties, and this labour-intensive production method creates its unique character.
How long does it take to make Champagne?
A minimum of 15 months from harvest to release for non-vintage, and 3 years for vintage Champagne. Many producers age their wines significantly longer.
What creates the bubbles in Champagne?
The second fermentation inside the sealed bottle produces carbon dioxide that dissolves into the wine, creating the mousse (bubbles). This is fundamentally different from carbonation added artificially.
What is riddling in Champagne production?
Riddling (remuage) is the process of gradually rotating and tilting bottles to move sediment into the neck for removal. It can be done by hand or using automated machines called gyropalettes.
Why does Champagne taste like brioche or toast?
These flavours develop during extended ageing on lees. As yeast cells break down (autolysis), they release compounds that create these distinctive toasty, biscuity notes.
