Dunkin’ Caffeine Content Chart

Dunkin’ brews stronger coffee than most people expect. A medium Original Blend carries roughly 210 mg of caffeine, which is more than a large Tim Hortons and close to a Starbucks grande. This page lists every drink by size.

Health Canada guidance puts the recommended daily caffeine limit for healthy adults at 400 mg, and 300 mg for people who are pregnant. Two medium Dunkin’ coffees put you near the adult limit.

Espresso Drinks

Espresso drinks are more predictable than brewed coffee because caffeine comes from a fixed number of shots rather than brew strength. A small is one shot on most drinks, medium and large are two.

Dunkin’ sits between Tim Hortons and Starbucks on brewed coffee, closer to Starbucks. On espresso drinks all three are roughly equivalent because shot counts are standardised across the industry.

How to Get Less Caffeine

GoalOrder
Under 20 mgDecaf, Coolatta, hot chocolate, chamomile tea
Under 80 mgSmall latte, green tea, small refresher
Under 150 mgMedium latte, small brewed coffee, medium refresher
Half caffeineAsk for half-caf on brewed coffee

Half-caf is available on brewed coffee at most locations at no extra charge. On espresso drinks, asking for one shot instead of two on a medium halves the caffeine.

Frequently Asked Questions

How much caffeine is in a medium Dunkin’ coffee?

About 210 mg for Original Blend or Dark Roast. That is roughly 50 percent more than a medium Tim Hortons.

Which Dunkin’ drink has the most caffeine?

An extra large Midnight Roast at roughly 370 mg, followed by extra large Original Blend at 360 mg. Both sit close to the 400 mg daily guidance for healthy adults.

Does cold brew have more caffeine than iced coffee?

In a medium, yes: about 220 mg against 198 mg. In a large the order flips, because iced coffee scales up with volume while cold brew is served at a more consistent concentration.

Slightly weaker on brewed coffee and roughly equal on espresso drinks. A medium Dunkin’ at 210 mg against a Starbucks tall at about 235 mg.

How much caffeine is safe per day?
