Concept
Dosage
The small amount of sugar solution added to champagne after dégorgement to balance the final taste.
What dosage does
After the second fermentation, champagne rests on the dead yeast for months. Just before shipping, that sediment is removed by dégorgement. An empty space then opens in the bottle, which is topped up with a mix of wine and sugar. That addition is called liqueur de dosage or liqueur d’expédition.
The sugar concentration determines the label term. The Comité Champagne fixes the boundaries in the regional code (EU regulation 2009/606).
The dosage scale
From dry to sweet:
| Term | Residual sugar (g/l) | In short |
|---|---|---|
| Brut Nature | 0 – 3 | No added sugar. Pas Dosé, Zero Dosage. |
| Extra Brut | 0 – 6 | Increasingly popular with growers. |
| Brut | up to 12 | The de-facto standard, ~95% of Champagne. |
| Extra Sec / Extra Dry | 12 – 17 | A light sweet touch, uncommon. |
| Sec | 17 – 32 | Off-dry, a classic with dessert. Almost gone. |
| Demi-Sec | 32 – 50 | Clearly sweet, dessert range. |
| Doux | > 50 | Almost extinct, occasionally revived. |
Important: the two driest categories (Brut Nature and Extra Brut) technically overlap.
Extra Brut may also be 0 g/l, but is more often used between 3 and 6 g/l when a house deliberately doesn’t want to claim “Nature”.
Why the addition exists
Champagne is naturally so acidic that any imbalance risk lies on the sharp side. A few grams of sugar rounds out those acids without making the wine sweet. At Brut of nine grams the average drinker tastes no sugar, just more fruit and generosity.
Climate change is shifting the goalposts. In years when grapes ripen riper, many houses have lowered their standard dosage. What sat at twelve grams in 1990 now often sits around seven or six.
What dosage isn’t
The standard line says lower dosage equals higher quality. Not true. Brut Nature is unforgiving. Every flaw in the base material, every unripe grape, every shortfall in ageing is exposed.
A well-dosed Brut at eight grams can be more elegant than a botched Brut Nature from the same house. Dosage is a tool, not an ideology. The question is always whether the wine is better with or without sugar, not which number belongs on the label.
In practice
If you want to learn to taste, try buying the same cuvée in two dosage versions if a producer offers that. The difference between Extra Brut and Brut from the same house is often four or five grams, enough to shift acid perception noticeably.
At the table, higher dosage works with spicier dishes. Lower dosage works with raw shellfish and sashimi, where every gram of sugar would stand out.
Deeper read per style
- Brut Nature — strictest dryness, for those who want the base wine more naked
- Extra Brut — sweet spot for many grower-producers
- Brut — universal standard
- Demi-Sec — with dessert, foie gras, blue cheese
