How Much Caffeine In Medium Dutch Bros Rebel? | Real Range

A medium Dutch Bros Rebel contains approximately 114 to 165 mg of caffeine, with reports from third-party sources varying widely — no official.

You order a medium Rebel from the drive-thru, take a sip, and wonder: just how much caffeine is actually in this electric-blue drink? The Rebel isn’t a coffee — it’s an energy drink, and its caffeine content has become a guessing game for fans because Dutch Bros doesn’t list the number on its official menu.

The honest answer is that a medium (16 oz) Rebel appears to contain somewhere between 114 mg and 165 mg of caffeine, depending on which independent source you check. None of those numbers come from Dutch Bros itself, so the real answer lives in a range rather than a single hard figure.

What The Numbers Say

Third-party menu sites keep track of Dutch Bros items because the company itself only provides a general caffeine information page without drink-specific amounts. That page notes the brand serves caffeinated beverages but directs customers to ask in-store for exact numbers.

Dbrosmenu.com reports a medium Rebel at 114 mg of caffeine. Umamicart lists 160 mg for the same 16 oz size. Another aggregator, D-brosmenu.onl, puts the figure at 165 mg. All three are independent — none are official — so the true number likely falls in that range.

The canned Blue Rebel, sold in stores, offers a fixed point: 80 mg per 8.4 oz can. That’s roughly 9.5 mg per ounce. If the fountain Rebel uses a similar concentration, a 16 oz serving would come out near 152 mg — right in the middle of the range reported by third parties.

Why The Caffeine Count Isn’t Simple

Energy drinks served from a fountain or dispenser can vary batch to batch. Syrup pumps, ice volume, and dilution all affect the final caffeine content. Dutch Bros also offers the Rebel in dozens of flavors, and some may include additional caffeine from added shots or concentrates.

• Size differences: Small (12 oz) ranges from 76 to 128 mg; large (24 oz) from 151 to 240 mg. The medium sits in between — roughly 114–165 mg.
• Flavor variation: Some sources suggest flavor syrups or added boosters can change the caffeine load, though no official data confirms this.
• No standard recipe posted: Unlike the canned Blue Rebel, which is consistent, the fountain Rebel recipe is proprietary and not publicly disclosed.
• Individual dispenser differences: A Rebel poured at one location may differ slightly from another due to equipment calibration or staff preparation.

For most people, the caffeine range is safe — 114–165 mg is less than a typical 16 oz brewed coffee (around 200–300 mg) — but if you’re sensitive to caffeine, the uncertainty matters.

How The Medium Stacks Up By Size

To get a clearer picture, look at how the medium compares across all sizes. The table below compiles numbers from three third-party sources so you can see the spread.

*Extra large figures are reported inconsistently; the ~240 mg figure for 32 oz comes from one source and may not reflect all stores.

The medium Rebel, based on the medium Rebel caffeine data from Dbrosmenu, sits at the lower end of the range, while Umamicart and D-brosmenu.onl place it higher. Without an official announcement, the best approach is to treat the number as approximately 140 mg and adjust expectations from there.

Factors That Can Shift The Caffeine Amount

1. Ice level: A “light ice” request means less dilution, so the same volume of concentrate yields more caffeine per cup. A “heavy ice” order does the opposite.
2. Added boosters: Dutch Bros offers caffeine “shots” or “extra shots” that can be added to any drink, including the Rebel. A medium with a double shot could push caffeine well above 200 mg.
3. Flavor syrups: While most syrups are caffeine-free, some specialty flavors (like those with added guarana or yerba mate) may bring extra caffeine.
4. Blended vs. iced: A blended Rebel (frozen) incorporates more air and ice, so the actual liquid volume and caffeine content per ounce may be slightly lower than an iced version.
5. Store variability: Baristas may follow slightly different pour recipes. One menu aggregator notes that “caffeine content can vary slightly based on the size and flavor of the drink.”

If you’re tracking your caffeine intake strictly, ask your barista if the store can tell you the approximate milligrams for that specific drink. Many locations have internal guidelines even if the brand doesn’t publish them online.

How The Rebel Compares To Other Energy Drinks

The medium Rebel’s caffeine range puts it in the same ballpark as major energy drink brands, though a bit lower than some. The table below shows how it stacks up against standard 16 oz servings of common competitors.

One source, Umamicart, puts the 160 mg medium Rebel figure directly in line with Monster and slightly above Red Bull. The 114 mg figure on the lower end is closer to a standard 12 oz energy drink. Either way, the Rebel is a moderate-caffeine choice — not the strongest, but definitely not caffeine-free.

The Bottom Line

A medium Dutch Bros Rebel carries roughly 114 to 165 mg of caffeine, but the exact number depends on whom you ask. Since the company doesn’t publish a specific figure, treat the range as a guide: expect around 140 mg for a standard 16 oz iced version, and adjust for ice, flavor, and any added boosters. If you’re sensitive to caffeine or have a medical condition that limits your intake, ordering a small or asking for a “half-caff” option (if available) is a safer bet.

For personalized advice on caffeine limits — especially if you’re pregnant, nursing, or managing a heart condition — your doctor or a registered dietitian can help you set a daily cap that works for your specific health picture and then match it to the menu options at Dutch Bros.
