That’s because no one can decide what it actually is. Secret menu items at Starbucks aren’t official, so each barista kind of has to make it up as they go.

There’s Purple Drink with Berry Hibiscus or Passion Iced Tea, Purple Drink with coconut milk or soy milk and Purple Drink with or without a pump of vanilla.

Also, it apparently contains caffeine, so though it’s pretty, you may be better off not giving it to little kids.

Whatever it’s made out of, people can’t get enough. I had the Pink Drink a while ago, and it was pretty good (if a little sweet), so I’m definitely intrigued. I’m also excited that both Pink and Purple Drink seem to be vegan. Having a lighter, nondairy alternative to the Frappuccino is just what my summer needed.
