In the United States, the standard method for determining beer color is the Standard Research Method. This technique was originally set up to approximate the Lovibond scale and is now used as the basis for assigning Lovibond ratings to grains as well as to determine the actual color of finished beer. Color measured as degrees SRM. Assumed to be equivalent to the older degrees Lovibond system. To convert to European Brewing Convention (EBC) color values use the following equation for a reasonable approximation EBC = 2.65 × SRM - 1.2.
