how much caffeine is in the starbucks refresher powder
It is very simple to look at Starbucks nutritional information to answer this question. I recommend the author use Google a bit before multiplying Quora questions. 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.
