Zero Dosage refers to a term commonly associated with sparkling wine, particularly Champagne. The word "dosage" in winemaking refers to a small amount of liquid, usually a mixture of wine and sugar, that is added to the bottle of sparkling wine after the sediment has been removed through disgorgement. This dosage helps adjust the sweetness level and balance the acidity in the final product.

A "Zero Dosage" or "Brut Nature" sparkling wine, on the other hand, indicates that no additional sugar is added during the final bottling stage. This style results in a drier and more crisp sparkling wine, allowing the natural flavors of the grapes and the characteristics of the fermentation process to shine through without the influence of added sweetness. It is a choice often preferred by those who appreciate a more austere and bone-dry profile in their sparkling wines.
