The color differences that coffee beans display after roasting are not arbitrary; the industry long ago established a scientific quantitative standard—the Agtron color value, also known as the caramelization analysis number. This set of values runs from 95 to 25, corresponding to eight levels from light roast to Italian roast: the higher the number, the lighter the color, and the lower the number, the darker it is. Each color value range has a clear drop time node and flavor characteristics: from light roasts dominated by bright acidity, it gradually transitions to dark roasts dominated by bitterness and smoky notes. Understanding these color values not only helps us recognize the correspondence between roast level and taste, but also helps us understand why very dark roasts are now hard to find under the specialty coffee trend. But color value is only a reference tool; in actual judgment, tasting perception is still needed, since factors such as processing method also affect the appearance of the beans. [more…]
