Only in the last seconds of its production does a Champagne get its final taste. Champagne dosage is the amount of sugar added after disgorgement in the form of a liqueur d’expédition, and that addition decides whether a wine reaches the market as Brut Nature, Brut, Demi-Sec or Doux. It is not a detail. It is one of the rare moments when the producer can still correct, or define, what the wine should be.
What the liqueur d’expédition is
After the second fermentation and the long rest on the lees, a deposit of dead yeast collects in the neck of the bottle. At disgorgement that deposit is ejected, leaving the bottle short by a few millilitres. The space is filled with liqueur d’expédition: a mixture of Champagne wine (often from the same base or from older reserve wines) plus sugar.
The sugar is usually cane or beet sugar, in some cases concentrated grape must. The wine component varies sharply by producer and is an important quality distinction. Some houses use mature reserve wines or even oak-aged base wines for the liqueur, which adds texture and complexity. Others simply use the standard base.
How much sugar goes where
The categories, measured in grams of residual sugar per litre after the liqueur is added:
- Brut Nature / Pas Dosé / Dosage Zéro: 0 to 3 g/L, with no added dosage.
- Extra Brut: 0 to 6 g/L.
- Brut: 0 to 12 g/L.
- Extra Dry / Extra Sec: 12 to 17 g/L.
- Sec: 17 to 32 g/L.
- Demi-Sec: 32 to 50 g/L.
- Doux: more than 50 g/L.
Brut remains by far the most-asked-for category, with most cuvées between 6 and 10 g/L. Second most popular is Extra Brut, between 3 and 6 g/L. Both are the modern norm for gastronomy.
What dosage does to taste
Three to six grams of sugar per litre sounds little, but the effect on the palate is real. Dosage:
- Softens acidity. Champagne is naturally high in acid. A few grams of sugar take the sharp edge off, especially in cooler vintages or younger base wines.
- Builds roundness and mouthfeel. Sugar acts on the tongue as a textural element, not only as a flavour.
- Lifts perception of fruit. The ripe-fruit profile comes forward more clearly at higher dosage.
- Buffers against early oxidation after disgorgement. A light dosage helps keep the wine stable in the first months on the market.
Dosage is not all upside. Too much dosage masks terroir, hides faults in the base wine, and can leave a wine flat or sticky. The modern trend towards very low dosage is a response to those historical excesses.
The modern trend: lower and lower
Over the past twenty-five years the average dosage in Champagne has steadily fallen. Three factors made that possible:
- Climate change. Higher average temperatures mean riper grapes. Lower natural acidity means less sugar is needed for balance.
- Better vineyard practice. Lower yields and stricter harvest work produce riper material with better phenolic maturity.
- A shift in market taste. Sommeliers and enthusiasts want to see terroir, not sugar. Brut Nature and Extra Brut have moved from marginal categories to a premium segment.
Krug usually doses Grande Cuvée at 6 to 8 g/L. Dom Pérignon sits around 5 g/L. Roederer Cristal has been below 8 g/L since 2013. Many growers work structurally under 4 g/L. Fifteen years ago 10 to 12 g/L was the norm; today that counts as high.
What this means for the drinker
A few practical consequences:
- A modern Brut feels drier than a Brut from fifteen years ago, even though the category is identical. Anyone who remembers a 2010 Brut as “reasonably dry” will taste a 2026 Brut as “bone dry”.
- An Extra Brut is now, at most houses, the “normal” taste, comparable to what a Brut was ten years ago.
- Brut Nature demands a riper base. With cool-climate vintages or younger wines it can turn angular. With ripe years and long autolysis it works beautifully.
- Tech sheets increasingly state the exact dosage figure, sometimes down to the gram. That is not a detail; it is information the drinker can use.
The role of post-dosage rest
After dosage and recorking, a bottle needs time to integrate the addition. Straight after disgorgement, the wine often tastes angular and disjointed. Most good producers keep their cuvées three to six months in the cellar after disgorgement before sending them to market. For R.D.-style wines (Récemment Dégorgé) that window is deliberately short to preserve autolytic texture, with a drinking recommendation of one to two years.
How to spot it on a bottle
The dosage category always appears on the label. The exact g/L figure rarely sits on the bottle but does appear on the tech sheet, which you can request via the producer’s website. The disgorgement date is a valuable piece of data that more and more producers now print on the back, giving a handle on the wine’s age from the moment it hit the market.
