Coffee is a tree in the genus Coffea of the Rubiaceae family and the drink made by mixing the powder obtained by roasting and grinding the fruit seeds of this tree with water or milk.

It is thought that the origins of the coffee plant are based on Ethiopia, and its use as a drink was first carried out in South Arabia. Coffee, which was moved to Europe through Venetian merchants in the 17th century, soon spread to the continent. As a result of European colonialism carried out on the Americas, Asia and Africa, coffee plantations were established in various parts of the world, and coffee became a widely consumed drink in the world. Today, coffee is mainly cultivated in tropical climate and elevated regions, especially in Brazil, Vietnam and Colombia.

Coffee is created by brewing powdered coffee grains as a drink, but different factors such as filtering, grinding size, brewing time, water temperature and quantity can lead to different drinks. Today, many types of coffee are consumed in the world, especially Espresso and its derivatives, which are a kind of filtered coffee.
Coffee has a attention-enhancing and alert-retaining feature due to the stimulating nature of the caffeine it contains.
