Coffee beans refer to the seeds or berries of the coffee plant, which are roasted and ground to make coffee. These small brown beads contain various compounds that give coffee its distinct flavor and aroma when brewed. The process of transforming raw coffee cherry into coffee beans involves several steps such as harvesting, processing, drying, hulling, and roasting. Once the outer layers are removed, what remains is the small but potent seed that contains all the rich flavors we associate with a good cup of coffee.
