Coffee is a popular beverage made from roasted coffee beans, which are the seeds of the Coffea plant. The two most commonly cultivated and commercially important species of coffee plants are Coffea arabica and Coffea canephora (commonly known as Robusta). The process of making coffee typically involves grinding the roasted beans and then brewing them with hot water. There are various methods of brewing coffee, including drip brewing, espresso, French press, and more.
