What is an agtron value?

An Agtron value is a numerical measurement used to assess the color and quality of roasted coffee beans. It is determined using a spectrophotometer that measures the light reflectance of the coffee surface, with lower values indicating darker roasts and higher values indicating lighter roasts. This system helps roasters and consumers evaluate and maintain consistency in coffee roasting profiles. Agtron values are often used in conjunction with cupping to provide a more comprehensive understanding of a coffee's characteristics.
