Question: how much caffeine is in a starbucks refresher?
Answer: 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. According to Starbucks each Via Refreshers packet contains 40-55mg of caffeine.
