This source highlights the two most important commercial coffee species: Coffea arabica and Coffea canephora (Robusta), detailing their significant presence across key producing regions. South and Central America dominate Arabica production, with Brazil standing out as the largest overall producer, while Africa and the Middle East are celebrated as coffee's birthplace, offering diverse flavor profiles and being home to Ethiopia, the largest African producer. Finally, Asia and Southeast Asia are noted for their substantial Robusta output, with Vietnam recognized as the world's leading Robusta producer and second-largest coffee producer overall.  NotebookLM
