What is SRM?

The Standard Reference Method, abbreviated as SRM is the color system used by brewers to specify finished beer and malt color.

SRM was adopted by the Ameican Society of Brewing Chemists in 1951. Brewers impose a first impression on their drinkers with the colour of their beers and this chart is helpful in determining the quality and taste of a beer.
