What's the shelf life on a coke or pepsi.
Unopened Coke and Pepsi have a shelf-life of 6 to 9 months past a “sell by date” or “best by date” in both the pantry and the refrigerator. Open cans are good for 1 day in the pantry and refrigerator and open bottles remain good around 3 days in both the pantry and refrigerator. Diet Coke and Diet Pepsi have a shelf-life of around 2 months past a “sell by date” or “best by date” in both the pantry and the refrigerator.
Coca-Cola and PepsiCo recently agreed to reduce the amount of 4-MEI caramel coloring in its products in order to avoid cancer labels on cans and bottles. The FDA says that humans would have to consume more than a thousand cans of soda a day “to reach the doses administered in the studies that have shown links to cancer in rodents.”
