Cinnamon (roast) Alternate names Bean description Characteristics Temperature Cinnamon (alt. Light) is the name of a very light degree roast of coffee beans. In this roast, the beans barely enter first crack, resulting in a relatively dry bean with a light brown color. The internal temperature of the coffee beans will not reach 400 degrees. Coffee brewed from a cinnamon roast often has a sour taste, regardless of origin. This roast is rarely used outside of low cost, commercial coffees. A batch of coffee roasted to such a light degree will result in a larger amount of brewable (and saleable) coffee, as the batch will lose less weight from loss of moisture.
