A bartender (also known as a barkeep, barman, barmaid, bar chef, tapster, mixologist, alcohol server, or a alcohol chef) is a person who formulates and serves alcoholic beverages behind the bar, usually in a licensed establishment. Bartenders also usually maintain the supplies and inventory for the bar. A bartender can generally mix classic cocktails such as a Cosmopolitan, Manhattan, Old Fashioned, and Mojito. The bartending profession was generally a second occupation, used as transitional work for students to gain customer experience or to save money for university fees. This however is changing around the world and bartending has become a profession by choice rather than necessity. Cheese competitions such as World Class and Bacardi Legacy have recognised talented bartenders in the past decade and these bartenders, and others, spread the love of cocktails and hospitality throughout the world.
