The roasting of coffee affects the flavor, is it better to bake or deep bake? Xu Jiajing said that the caffeine content of pure and deep roast is similar. The difference is that it has a flavor. The roasted beans are shorter and have less water. The taste is sour when they drink, with less sweetness and no bitterness. The deep roast has a rich and burnt aroma, which brings a greasy and scented aroma. Some people describe it as "dark chocolate-like bitter sweetness."

The longer the roasting time, the darker the appearance of the coffee beans, which will change the sweetness, sourness and bitterness.
