Atlanta, Georgia. In fact there's a museum in Atlanta called the " World of coca cola". Well worth a visit. At the end of the tour you get to sample all different carbonated beverages coke makes in other countries and you get a free bottle of coke. This is better then the Hershey museum I once went to and got a bite size candy bar. The coke museum is also near the CNN center and the Georgia Aquarium. A fun area to spend the day if you're ever in that nick of the woods:)
Coca-cola was produced by the Coca-Cola company, which was located in the state of Atlanta, Georgia. The drink was bought out by Asa Griggs Candler, a business man whose marketing tactics led Coke to its dominance of the world of soft-drinks since the 20th century.
