The products of the caramelization reaction include various compounds that contribute to the aroma, flavor, and color development in coffee beans. When caramelization is insufficient, the coffee may lack sweetness and complexity, while excessive caramelization can lead to bitter, burnt flavors that mask the coffee's inherent characteristics.
