                                According to Starbucks' nutritional information for past iterations, a Grande-sized Very Berry Hibiscus Refresher typically contains around 45 to 55 milligrams of caffeine. This moderate amount is derived from green coffee extract, not traditional brewed coffee, making it a popular choice for those seeking a lighter energy boost.
