What does it indicate if a wine is labeled as “dry”?

When a wine is labeled as "dry," it indicates that it has little to no residual sugar remaining after fermentation. This means that the fermentation process has converted the majority of the naturally occurring sugars in the grape juice into alcohol, leaving the wine with a very low sugar content. As a result, dry wines typically lack the sweetness that characterizes off-dry or sweet wines, offering a more straightforward expression of the grape’s characteristics.

The perception of dryness in wine is directly linked to its sugar content, making option B the clear answer. In contrast, high acidity levels can contribute to the overall taste and mouthfeel of a wine but do not define whether it is dry or sweet. A fruity flavor profile might exist in both dry and sweet wines, and the presence of sweetness would contradict the definition of a dry wine. Therefore, the key attribute of a dry wine is its minimal residual sugar, which defines its classification.
