According to product facts from PepsiCo, a standard 20 oz bottle of Mountain Dew contains 90 mg of caffeine. This fact is important for understanding how much caffeine is in 20 oz of dew and how it stacks up against other popular beverages for those mindful of their daily intake.

While often labeled as containing zero calories, a 32 ounce diet Mountain Dew can technically contain a few, with some retail-specific versions listing up to 15 calories. This discrepancy is largely due to FDA labeling rules that permit products with less than 5 calories per serving to be rounded down to zero. Understanding this allows for a more accurate perspective on your caloric intake, especially when consuming larger fountain drink sizes.
