Nuka Cola

https://fallout.fandom.com/wiki/Nuka-Cola "Nuka-Cola is the flagship product of the Nuka-Cola Corporation and one of the symbols of United States culture. Introduced in 2044, it rapidly dominated the soft drink market, eventually becoming the most popular soda on the market and a staple of American culture. Bottled and distributed nationwide, Nuka-Cola was available in such numbers that even two centuries after the Great War put a stop to all bottling operations, Nuka-Cola bottles can still be found in the wastelands in large quantities. In the aftermath of the Great War, Nuka-Cola bottle caps became the de facto currency in most post-War societies."
