Question: how much caffeine is in a starbucks refresher vs coffee?
Answer: The Refreshers are listed as having 60mg of caffeine in the Grande (16oz) size. [1] A black iced coffee in the same size has 165mg of caffeine. [2] A Grande hot coffee has 330mg of caffeine. [3] So, clearly, the Refreshers have a respectable amount of caffeine, but nothing near that of typical, brewed coffee.
