auxiliary information: Coca-Cola is a carbonated soft drink sold in stores, restaurants, and vending machines throughout the world. It is produced by The Coca-Cola Company of Atlanta, Georgia, and is often referred to simply as Coke. Originally intended as a patent medicine when it was invented in the late 19th century by John Pemberton, Coca-Cola was bought out by businessman Asa Griggs Candler, whose marketing tactics led Coke to its dominance of the world soft-drink market throughout the 20th century. The name refers to its ingredients: kola nuts, a source of caffeine, and coca leaves. The formula of Coca-Cola remains a trade secret. The company produces concentrate, which is then sold to licensed Coca-Cola bottlers throughout the world. The bottlers, who hold territorially exclusive contracts with the company, produce finished product in cans and bottles from the concentrate in combination with filtered water and sweeteners. The bottlers then sell, distribute and merchandise Coca-Cola to retail stores and vending machines. The Coca-Cola Company also sells concentrate for soda fountains to major restaurants and food service distributors.
