Which SRM value represents a brown-colored beer?

The correct SRM value that represents a brown-colored beer is indeed 20. The Standard Reference Method (SRM) is a scale used to measure the color of beer, with higher values indicating darker beers. Typically, brown beers have SRM values ranging from around 15 to 30, depending on the depth of color.

An SRM of 20 indicates a moderate brown hue, which is characteristic of many brown ales, dunkels, or mild ales. This depth of color suggests that the beer has likely undergone certain malt-intensive brewing processes, contributing to both its flavor profile and appearance.

Beers with lower SRM values, such as 9, usually fall into the golden or pale category and do not exhibit the brown characteristics associated with a higher SRM. Therefore, while an SRM of 30 might represent a darker beer, it goes beyond the typical range associated specifically with brown beers.
