Which parameters are considered quantitative when describing beer character?

The parameters that are considered quantitative when describing beer character relate to measurable aspects of the beer. In this case, ABV (Alcohol by Volume), IBU (International Bitterness Units), and SRM (Standard Reference Method) are all quantifiable values.

ABV is a percentage that indicates the amount of alcohol content in the beer, providing a direct measurement that can affect the beer's strength. IBU quantifies the bitterness degree of a beer, reflecting how much hops have been used in the brewing process, and can be numerically compared across different styles. SRM measures the color of the beer through a specific numerical scale, allowing brewers and drinkers to identify and expect the appearance of the beer based on its calculated color.

The other options contain qualitative descriptors or characteristics that are subject to individual perception and do not provide a numerical value, therefore they do not fall under quantitative parameters.
