                                A 12-ounce can of Coca-Cola contains 34 mg of caffeine, while a standard 12-ounce latte with a double shot of espresso typically contains around 128 mg. This stark difference means that, ounce for ounce, a latte has significantly more caffeine than a Coke. However, the total caffeine in a drink depends on serving size and preparation methods, factors that can shift the comparison in surprising ways.
