Coffee is a drink prepared from roasted coffee beans.
Darkly colored, bitter, and slightly acidic, coffee has a stimulating
effect on humans, primarily due to its caffeine content. It has the
highest sales in the world market for hot drinks.
Seeds of the Coffea plant's fruits are separated to produce unroasted green coffee beans. The beans are roasted and then ground into fine particles that are typically steeped in hot water before being filtered out, producing a cup of coffee.
It is usually served hot, although chilled or iced coffee is common.
Coffee can be prepared and presented in a variety of ways (e.g.,
espresso, French press, caffè latte, or already-brewed canned coffee).
The two most commonly grown coffee bean types are
Arabica and Robusta.
