Definition of roasting degree and taste of coffee
In recent years, the American Fine Coffee Association has strongly advocated the caramelization value (Agtron number) to determine the baking degree, using the red inner line to determine the caramelization degree of coffee beans. The higher the value, the lower the caramelization, that is, the shallower the baking degree, and the lower the baking degree, the deeper the caramelization, that is, the deeper the baking degree. With the data, we can more accurately understand the baking degree of coffee beans.
