                                According to the Center for Science in the Public Interest, a 13.7-ounce bottled Starbucks Mocha Frappuccino contains 105mg of caffeine. This ready-to-drink version has a different caffeine content than its in-store blended beverage counterpart, making it a common point of confusion for consumers seeking a specific caffeine boost.
