Sugar-Free Brewberry 7 Energy: Recipe & Calories
Brewberry is an unofficial customer creation at 7 Brew: blackberry and raspberry syrups in a 7 Energy, and the sugar-free version swaps in the sugar-free energy base and sugar-free syrups. The result is a dark-berry fizzy drink with around 10 to 20 calories in a medium and zero sugar, which is why it has a following among people cutting sugar but keeping caffeine. This post covers the recipe, what it tastes like, prices, calories, and caffeine, plus exactly what to say when you order. This is a fan-run site, not affiliated with 7 Brew. All figures below are estimates that vary by location.

What It Tastes Like
Blackberry leads with a deep, dark berry flavor: a little earthy, a little jammy, less bright than strawberry or blue raspberry. Raspberry comes in behind it with a sharper, more familiar fruit-punch note that lifts the whole drink. Together they taste layered rather than one-note, which is the whole appeal. The carbonation keeps it crisp, and the finish is clean, without the heavy syrup film some energy drinks leave behind. Sugar-free drinks can sometimes carry a noticeable aftertaste; the berry combination covers it well for most people, though sweetness perception varies from person to person. It looks the part too: a deep ruby-purple over ice. If you like dark berries, this is an easy favorite. If you prefer bright citrus flavors, you would be happier with something orange-forward.
Prices, Calories, and Caffeine (Estimates)
- Small: $6.83, 5-10 cal, ~70mg caffeine.
- Medium: $8.13, 10-20 cal, ~105mg caffeine.
- Large: $9.43, 15-30 cal, ~150mg caffeine.
Sugar-free syrups typically do not add an upcharge. Adding cream, cold foam, or extra syrups raises the calorie count.
How to Order It
Brewberry is not an official menu name, so say the word “sugar-free” twice, once for the base and once for the syrups: “Can I get a medium sugar-free 7 Energy with sugar-free blackberry and sugar-free raspberry syrup?”
If the barista does not recognize the name, the ingredient list above is all they need. A pump of sugar-free vanilla or coconut makes a creamier or more tropical variation.

FAQs
Is it actually sugar-free?
Yes, as long as both the energy base and the syrups are sugar-free. Adding cream, milk, or sauces introduces some sugar.
How many calories are in a medium?
Around 10 to 20 with the sugar-free base and sugar-free syrups.
Does it contain caffeine?
Yes, the 7 Energy base provides roughly 105mg in a medium.
Is Brewberry on the official 7 Brew menu?
No, it is an unofficial customer-created combination; order it by ingredients.
How much does it cost?
Around $6.83 for a small and up, depending on size. Prices vary by location.
Conclusion
The Brewberry works because blackberry and raspberry cover each other’s weak spots: depth from one, brightness from the other, over a clean sugar-free energy base. Learn the base recipe, then make it yours with a third syrup or a different sweetness level. For the full energy lineup, see Seven Energy. More customer creations live on the secret menu guide.
