The Standard Reference Method (SRM) is a number representing the color of a beer. Lighter values are lower and darker values are higher on the scale. SRM values over 40 are reported as black. This calculator is for approximation purposes and uses Morey's Formula to calculate: SRM = 1.4922 * (MCU ^ 0.6859). European Brewing Convention (ECB) is another measure of color and equals approximately 1.97 * SRM (Daniels).
