Why coffee has a bitter taste although it has a pH of 5?

In fact, coffee bitterness is attributable to a family of chemicals known as chlorogenic acids, which are also present in tea, peaches and prunes. Chlorogenic acids aren’t bitter themselves, but, when roasted, they transform into two related chemicals — lactones and phenylindanes.

Why does coffee taste bitter if it is acidic?

During roasting, especially after the first crack and at bean temperatures around 200 °C, chlorogenic acids are converted into the corresponding lactones in a splitting of one molecule of water. That is the crucial chemical step turning the acidic chlorogenic acids into bitter tasting chlorogenic acid lactones.
