Which of the following is NOT one of the six qualitative parameters of beer?

The correct answer indicates that carbonation is not considered one of the six qualitative parameters of beer. In the context of evaluating beer, the six qualitative parameters are typically flavor, aroma, appearance, mouthfeel (or body), alcohol, and aftertaste. These parameters help in assessing the overall quality and characteristics of a beer.

Carbonation, while it plays an essential role in the drinking experience and can affect mouthfeel, is often considered a factor that influences the other qualitative parameters rather than a standalone one. It refers to the presence of carbon dioxide and the resulting bubbles in the beer, which contribute to its texture and perceived crispness but does not directly define the qualitative characteristics in the same way that flavor or aroma do.

Therefore, understanding these distinctions helps clarify why carbonation does not fit into the list of qualitative parameters used to evaluate beer comprehensively.
