After champagne is made, winemakers must determine how sweet the wine is going to be. That’s when they use a certain amount of dosage. Dosage is usually added in the form of sugar or a combination of wine and sugar. This is done to balance out the acidity in the wine.
Acidity
Acidity in wine is the level of acid that the wine contains. Wines with more acid in them taste more tart or sour.
