What is one of the three quantitative parameters of beer characteristics?

One of the three quantitative parameters of beer characteristics is Alcohol by Volume (ABV). ABV is a standard measurement that indicates the percentage of alcohol contained in a beverage, calculated as a volume ratio. This measurement is vital for understanding the strength of a beer and plays a significant role in how consumers perceive and enjoy the drink.

ABV directly informs consumers about how alcoholic a beer is, which influences their drinking experience and choice. It's a key factor that distinguishes various beer styles, impacting everything from flavor to mouthfeel. Higher ABV beers often have a richer, fuller body and may exhibit different flavors compared to lower ABV options.

The other choices mentioned, such as aroma profile and flavor intensity, are qualitative characteristics rather than quantitative parameters. They describe aspects of flavor and aroma that contribute to the overall sensory experience of beer but do not offer a measurable statistic. Alcohol by weight, while technically accurate, is less commonly referred to than ABV, which is the standard used in most contexts. Thus, ABV is the most recognized and important quantitative characteristic in assessing beer.
