How Much Caffeine is in my Coffee Drink?

Hi,
Can you tell me what has more caffeine, Starbucks' Frappucino drink or a soda? Thanks, Danielle T.

Dear Danielle,

The content varies greatly depending on your serving size, but with this information you'll be able to figure out what you need to:

The average 12 oz can of soda has about 50 mg of caffeine. (If you have one of the 20 oz bottles, obviously this will contain more!) Colas have caffeine, but sodas like sprite, gingerale, root beer, or orange flavors do not.

A 9.5 oz Starbucks Frappucino has 115 mg caffeine.

Incidentally, the average cup (8 oz.) of coffee or 1 oz. shot of espresso has about 75 mg of caffeine.
