                                According to Starbucks' official nutrition information, a Grande (16 oz) Refresher contains between 45 and 55 milligrams of caffeine. When this popular drink is 'frosted,' or blended with coconut milk, the caffeine content does not change, as the source is the base concentrate. This makes understanding how much caffeine is in a frosted refresher fairly straightforward, but it's important to consider variations across different brands and drink sizes.
