Quick answer: A small Dutch Bros Rebel has about 80 mg of caffeine, a medium has about 114 to 120 mg, and a large has about 160 mg. These numbers come from Dutch Bros own nutritional guide, and they stay roughly the same no matter which flavor you order, since every Rebel starts from the same Blue Rebel energy base.
If you have ever stood at the menu board wondering whether a Rebel is basically a fancy Red Bull or something else entirely, you are not alone. This guide breaks down exactly what is in a Rebel, how much caffeine each size really has, how it stacks up against other popular drinks, and what to know if you are sensitive to caffeine. For everything else on the Dutch Bros menu, from coffee to seasonal drinks, we cover it all in detail.

What Exactly Is a Dutch Bros Rebel?
A Rebel is not “extra” anything added to a regular drink. It is Dutch Bros own proprietary energy drink, called Blue Rebel, which the company created in house instead of using Red Bull or Monster. Baristas pour the Blue Rebel base over ice or blend it with ice, then mix in your choice of Torani flavor syrup, such as Aftershock, Electric Berry, or Shark Attack.
So when you order a Rebel, you are ordering the Blue Rebel energy drink itself, flavored to your taste. It is not a booster shot added to coffee, and it does not contain espresso unless you specifically customize it that way.

Caffeine Content by Size
Here is the breakdown according to Dutch Bros published nutritional information. If you want a closer look at exact ounces for every cup at Dutch Bros, our Dutch Bros sizes guide covers hot, iced, and blended drinks side by side.
| Size | Volume | Caffeine (approx.) |
|---|---|---|
| Small | 16 oz | 80 mg |
| Medium | 24 oz | 114 to 120 mg |
| Large | 32 oz | 160 mg |
A few notes on accuracy. Caffeine amounts can shift slightly between iced and blended versions, and flavors with added cocoa or extra syrup pumps can nudge the number up a bit. But the core range holds steady across the menu, and Dutch Bros confirms these figures in its official nutritional guide, last updated in 2026.
Is the Caffeine in Rebel Natural or Synthetic?
Dutch Bros has not publicly stated whether the caffeine in Blue Rebel is naturally derived or manufactured synthetically. The ingredient list simply lists “caffeine” without specifying the source. For context, most mainstream energy drinks, including Red Bull and Monster, use synthetic caffeine rather than caffeine naturally extracted from coffee beans or tea leaves, since it is more consistent and cheaper to produce at scale. It is reasonable to assume Blue Rebel follows the same industry standard, though Dutch Bros has not confirmed this directly, so treat it as an educated inference rather than a confirmed fact.
How a Rebel Compares to Other Caffeinated Drinks
| Drink | Size | Caffeine (mg) |
|---|---|---|
| Dutch Bros Rebel (small) | 16 oz | 80 |
| Dutch Bros Rebel (medium) | 24 oz | 114 |
| Dutch Bros Rebel (large) | 32 oz | 160 |
| Red Bull | 8.4 oz | 80 |
| Monster Energy | 16 oz | 160 |
| Brewed coffee | 8 oz | 95 |
| Coca Cola | 12 oz | 34 |
A small Rebel lines up almost exactly with a can of Red Bull. A medium edges past a standard cup of brewed coffee. A large matches a 16 oz Monster Energy. If you want a moderate lift without tipping into “full energy drink” territory, a small or medium is usually the sweet spot.
How Many Calories Are in a Dutch Bros Rebel?
Calories vary by flavor and size, but a medium Rebel typically falls in the range of 200 to 250 calories, and can run higher with cream, boba, or extra syrup add ons. If you are watching your intake, asking for a sugar free syrup option is an easy way to cut both sugar and calories without losing the caffeine kick.
