Dunkin' Refreshers pack a fruity punch with a solid caffeine boost from green tea.
Exact amounts vary by size and type, but they're a popular pick-me-up without the coffee crash.

Caffeine Breakdown

Dunkin' Refreshers use brewed green tea as a base, delivering natural caffeine—typically 66mg in a small (16 oz) , 99mg in a medium (24 oz) , and 132mg in a large (32 oz) for standard green tea versions.

Coconut milk Refreshers have slightly less: around 45mg small , 68mg medium , and 91mg large.

No caffeine-free options exist right now, as the green tea extract in the fruit mix adds to the kick.

Why the Buzz?

Imagine grabbing a Blood Orange Refresher on a hot day—it's like sunshine in a cup, but that green tea base sneaks in energy equivalent to about half a medium Dunkin' coffee.

Forum chatter on Reddit shows some folks miss the caffeine entirely, thinking it's just fruity fizz, while others debate if baristas skip the green tea (spoiler: the concentrate has it built-in).

Swapping to lemonade cuts it a tad, but expect that lively lift either way.

Compared to Other Drinks

  • Vs. Dunkin' Iced Coffee (medium) : Refreshers have ~99mg vs. coffee's 150-200mg—milder buzz.
  • Vs. Soda (12 oz Coke) : More than double at 34mg, but way less sugar in some flavors.
  • Daily Limit Note : Adults cap at 400mg; a large is a third of that, so sip wisely if stacking with coffee.

Quick Tips

  • Sensitive to caffeine? Start small or ask for lemonade tweaks.
  • Kids/teens: Experts say skip it—medium hits near the 100mg youth limit.
  • Trending now (early 2026): Strawberry Dragonfruit is viral for its vibrant vibe and reliable 99mg medium kick.

TL;DR: 66-132mg depending on size—green tea powers the refresh!
