Although caffeine can also produce a bitter taste, it is negligible to chlorogenic acid (caffeine has carried the pan for chlorogenic acid for years).

Of course, baking will also affect the production of bitter taste, except that baking will convert chlorogenic acid into bitter chlorogenic acid lactone. With the deepening of the degree of baking, the caramelization reaction is more obvious. If the caramel temperature is too high or the time is too long, it will scorch and produce bitterness. This phenomenon is called carbonization. In the caramelization reaction, some flavor substances such as acidity are worn away, thus bringing out sweetness and mellow feeling.
