Quick answer: a Dutch Bros Rebel has 80 mg of caffeine per 8.4 oz can, small and medium espresso drinks both run on a double shot, larges get four shots, and the 911 tops the menu with six shots of espresso. Everything below comes from Dutch Bros' own published nutritional guide and independent compilations at Caffeine Informer.
The quirk nobody notices: medium equals small
Dutch Bros builds both the 12 oz and 16 oz espresso drinks on the same double shot, then doubles it to four shots at 20 oz. Upsizing from a small to a medium buys you more milk and syrup, not more caffeine. If you actually want a stronger drink, the move is a large or an extra shot, not a medium.
Caffeine by drink
| Drink | Small | Medium | Large |
|---|---|---|---|
| Plain Rebel (blended) | 80 mg | 120 mg | 160 mg |
| Blue Rebel (8.4 oz can) | 80 mg, same as a Red Bull of the same size | ||
| Latte or mocha (espresso base) | double shot | double shot, same as small | four shots |
| Cold brew | roughly 240 mg; nitro runs near 293 mg per compiled guides | ||
| 911 (six shots) | roughly 280 mg and the strongest standard order | ||
| Blended Brain Freeze (large) | compilations put it near 437 mg, the true menu ceiling | ||
Dutch Bros notes caffeine varies with the blend and flavor, and cocoa-based flavors add a few extra milligrams. The FDA puts the general daily guideline for healthy adults at 400 mg, which one large cold brew gets most of the way to on its own.

How Dutch Bros compares
Against the chains we've measured before: a grande Starbucks brewed coffee lands well above a Dutch latte, and a standard latte anywhere is a milder order than most of the Dutch menu. The Rebel line is the gentle end of this menu, not the strong end, which surprises people.
