After roasting, coffee beans will show different levels of bitter flavor, which is the inevitable phenomenon of coffee caramelization. If the baking time is not proper, the coffee will have a kind of difficult bitter feeling, and with the stale coffee beans, the bitter feeling will be particularly obvious.
