Question: how much caffeine is in a starbucks refreshers can?
Answer: Starbucks customer service stated that each can contains 40-55 milligrams of caffeine. Pepsico lists the caffeine content as 50mg. Their in store refresher has 45mg of caffeine per 12oz, but because of the ice used, I would expect the canned variety to have a bit more. Starbucks Refreshers also come in a Via packet.
