Traditional Method
The sparkling wine production method in which secondary fermentation — and hence carbonation — takes place inside the individual bottle; used for Champagne, Crémant, Cava, and many premium sparkling wines.
In depth
The traditional method (méthode traditionnelle, formerly called méthode champenoise) produces the finest sparkling wines. After a base wine is made, a mixture of wine, sugar, and yeast (liqueur de tirage) is added and the bottle is sealed. Secondary fermentation occurs in the bottle over several weeks, producing CO₂ which dissolves into the wine under pressure.
The spent yeast cells (lees) remain in the bottle during a period of lees ageing (at minimum 15 months for non-vintage Champagne, 36 months for vintage). During this time, autolysis occurs: the yeast cells break down and release compounds that contribute toasty, brioche, and biscuit aromas — the hallmark of premium traditional-method wines.
After ageing, riddling (remuage) gradually tilts the bottle so the lees collect in the neck. Disgorgement freezes the neck, the plug of lees is ejected under pressure, and a dosage (a mixture of wine and sugar) is added to adjust sweetness before the final cork is inserted.
The result is a wine with fine, persistent bubbles (smaller and more numerous than tank-method wines), complex autolytic characters, and greater ageing potential.

Frequently asked questions
- What is the difference between the traditional method and the tank method?
- In the traditional method, secondary fermentation happens inside the bottle, producing fine bubbles and autolytic (toasty, brioche) notes after extended lees contact. In the tank method (Charmat), secondary fermentation occurs in a sealed pressurised tank, preserving fresh fruit aromas. Champagne uses the traditional method; most Prosecco uses the tank method.
- Why are traditional-method sparkling wines more expensive?
- The traditional method is labour-intensive: each bottle undergoes riddling by hand (or gyropalette), extended lees ageing, individual disgorgement, and dosage addition. This adds significant time and cost compared to the tank method, where an entire tank is processed at once.
