Do any of these caffeine amounts surprise you? The amount of caffeine in a Dunkin’ iced coffee always throws me for a loop, but I’ve checked it a bazillion times and can confirm that is correct.
As a daily cold brew coffee drinker, I think it’s very useful to know how much caffeine you are actually consuming, so here’s a handy guide to help.
Caffeine amounts are always approximate and can vary a bit with different types of coffee beans/espresso, and they’ll change when you customize your drinks. But estimating is always the name of the game.
Shameless plug: I have nutrition calculators on my site for both Starbucks and Dunkin’ if you want to see the caffeine and full nutrition facts of your drinks. Just go through my bio link!
Some drinks listed here have tons of varieties (like frappuccinos and iced tea) so note that there may be slight differences depending on which one ya go with.
