If the coffee is not roasted well, even if the raw coffee beans are very good, you can't get good ripe coffee beans; as a result, you can't make good coffee. Only with good coffee raw beans, after proper roasting, is it possible to process good coffee cooked beans, and it is also possible to provide a good prerequisite for making good coffee.
