Liqueur d'Expedition
The "dosage" liqueur added to Champagne bottles to replace the volume of wine lost by disgorging the plug of spent yeast from the bottle is also called Liqueur d'Expedition. This liqueur always contains white wine and sometimes also contains sugar and/or brandy. By using dosage liqueurs of varying sugar contents, it is possible to produce sparkling wines of different sweetnesses from the same cuvee of sparkling wine. If the liqueur contains no sugar at all, the resulting sparkling wine will be bone dry and may be labelled "Brut."
