Coffee is a brewed drink prepared from roasted coffee beans, the seeds
of berries from certain Coffea species. When coffee berries turn from
green to bright red in color – indicating ripeness – they are picked,
processed, and dried.
Coffee is darkly colored, bitter, slightly acidic and has a stimulating
effect in humans, primarily due to its caffeine content. It is one of
the most popular drinks in the world, and can be prepared and presented
in a variety of ways (e.g., espresso, French press, caffè latte). It is
usually served hot, although iced coffee is common.
