Coffee is a brewed drink prepared from roasted coffee beans, the seeds of berries from certain Coffea species.
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. It is usually served hot, although chilled or iced coffee is common. Sugar, sugar substitutes, milk or cream are often used to lessen the bitter taste.A commercial establishment that sells prepared coffee beverages is known as a coffee shop
