SRM (Standard Reference Method) is utilized to measure what aspect of beer?

SRM, or Standard Reference Method, is an established technique used to quantify the color of beer. This measurement involves analyzing the light passed through a beer sample, which is then compared to a standard scale to determine color intensity. The SRM values range from pale yellow (for lighter beers) to deep brown or black (for darker beers).

This method is crucial for brewers and beer enthusiasts alike, as color can significantly influence the perception and expectations of a beer's flavor and style. While alcohol content is measured using different techniques such as hydrometry or refractometry, bitterness is quantified by the International Bitterness Units (IBU) scale. Aroma intensity, on the other hand, is assessed through sensory evaluation rather than a standardized measurement method like SRM. Thus, using SRM specifically relates to the evaluation of the color of beer.
