Coffee is a beverage 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.
The 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). Sugar, sugar substitutes, milk,
and cream are often added to mask the bitter taste or enhance the
flavor.
