If you’re wondering what Starbucks menu item has the highest caffeine content, it’s Blonde Roast coffee, which contains 475 milligrams of caffeine in every 20-ounce venti serving.

Blonde Roast is Starbucks’ lightest brew, and because lighter roasts are made from denser beans, they can have more caffeine.

Lovers of cold caffeinated drinks can also enjoy a sizeable dose of caffeine with Starbucks' Iced Espresso Roast Clover, which contains 470 milligrams in a 24-ounce venti serving.

If you want to downsize from a large venti drink but still want to turbo-charge your caffeine intake, you can customize your Starbucks order to get the desired amount.

Keep in mind the recommended limits for caffeine consumption. According to the U.S. Food and Drug Administration, a healthy adult can safely consume 400 milligrams of caffeine daily.
