What is the traditional method (méthode champenoise)?

If you've ever wondered why Champagne costs more than Prosecco, the traditional method is a big part of the answer. It's a painstaking, time-intensive process that no shortcut can replicate.

It starts with making a still base wine — usually quite tart and unremarkable on its own. The winemaker then adds a precise dose of sugar (24 g/L) and yeast to each bottle, caps it, and lets a second fermentation happen inside the glass. This trapped fermentation creates roughly 5-6 atmospheres of pressure — about three times the pressure in a car tyre.

Here's where the magic really happens: the dead yeast cells (lees) remain in the bottle for months or years. As they break down (autolyse), they release compounds that create those gorgeous toasty, brioche, and almond notes you associate with fine Champagne. By law, non-vintage Champagne must age on lees for at least 15 months, vintage Champagne for 36 months — but prestige cuvées often rest for 5-10 years.

After ageing, the yeast sediment needs to come out. Through riddling (remuage), bottles are gradually tilted neck-down so the sediment collects in the cap. Then comes disgorgement: the neck is frozen to -25 °C, the cap is popped, and the frozen plug of sediment shoots out. A small dosage of wine and sugar is added to set the sweetness level — from Brut Nature (bone dry, 0-3 g/L sugar) to Demi-Sec (noticeably sweet, 32-50 g/L).

Beyond Champagne, look for Crémant (from Alsace, Burgundy, Loire), Cava from Spain, and Franciacorta from Italy — all made this way, often at friendlier prices.
