A Different Situation
The situation with the yellow bottle cap is a little different. Like the colored cans, they’re limited. There is a slight difference in the ingredients of the drink if it comes in a bottle with a yellow cap compared to the formula used in regular Coca-Cola. The colored cap may not indicate a specific flavor, but the drink’s formula is unique. However, many people are unlikely to notice the difference.
A Different Sweetener
The drink inside bottles with yellow caps does not contain high-fructose corn syrup, unlike regular Coca-Cola. Instead, those beverages contain sucrose, a sweetener derived from both cane sugar and beet sugar. On paper, that may appear to be a bit random, but there’s a reason why the drinks behemoth chose to replace only one component while keeping everything else the same. And the move is aimed at a specific demographic.
