Why Does Cocoa Taste Bitter?
Cocoa beans naturally contain a compound called polyphenols, which give cocoa its bitter taste. These are antioxidants that plants produce for protection against insects and other predators. The level of bitterness varies based on the type of cocoa beans used, as well as how the beans are processed and roasted. High-quality chocolate usually has a balance of bitterness and sweetness, which is achieved through careful selection and processing of the cocoa beans.
