Coffee is a brewed drink made from roasted coffee beans, which come from the seeds of berries from the Coffea plant native to Africa. Coffee plants are now cultivated in over 70 countries, and the most common varieties are arabica and robusta. Once picked, coffee beans are processed, dried, roasted, ground, and brewed to produce coffee. The earliest evidence of coffee drinking was in 15th century Yemen, and it later spread throughout the Middle East, Africa, Europe, Asia, and the Americas. Today, Brazil is the largest coffee producer though Vietnam and Indonesia are also major producers. Coffee is often consumed alongside meals or as part of social gatherings like coffee breaks.
