What is brewed coffee primarily made from?

Brewed coffee is primarily made from roasted coffee beans, which are the seeds of the Coffea plant. The process involves grinding these roasted beans and then extracting flavors and compounds by brewing them with hot water. The roasting process enhances the beans' natural flavors and aroma, which are essential components in a well-prepared cup of coffee.

Fresh vegetables and ground spices do not contribute to the main components of brewed coffee. Instant coffee powder is a form of brewed coffee but not the primary source used in traditional brewing methods, which rely on whole or ground roasted beans. This distinction highlights the centrality of roasted coffee beans in creating the authentic coffee experience that many enjoy.
