Fruity, but not caffeine-free

Starbucks Refreshers get their caffeine from green coffee extract, not from the fruit juice or flavouring, which is why a drink that looks and tastes like juice still carries a real dose: 25 mg in a Tall, 50 mg in a Grande, 75 mg in a Venti, and 100 mg in a Trenta. Someone expecting a caffeine-free fruit drink, unlike a genuine herbal tea at 0 mg, would be surprised by the Trenta’s 100 mg.

The Pink Drink shares this base

Starbucks’ Pink Drink is this Refresher made with coconutmilk instead of water, and carries the same caffeine from the same green coffee extract base at each size.

A much smaller dose than the Energy version

This is the standard Refresher, not the Strawberry Açaí Energy Refresher, which adds extra caffeine and carries 100 mg in a Tall alone, twice this drink’s Grande.

Ordering with lemonade or coconutmilk

Starbucks offers this Refresher with water, lemonade, or coconutmilk as the base. Swapping the liquid changes the flavour and calories but not the caffeine figure listed here, since the dose comes from the Refresher concentrate itself rather than whatever it’s mixed into.

Where it fits in a day

At 50 mg, a Grande is far under the 200 mg single dose EFSA assessed as safe for healthy adults. Even a Trenta, 100 mg, is a quarter of the 400 mg daily figure the FDA cites. In pregnancy, where ACOG uses a 200 mg daily ceiling, two Trentas use the whole day’s allowance.
