What is the 7 Brew Heatwave?
Heatwave is a signature 7 Energy flavor. The same three citrus flavors are also sold as a Heatwave lemonade.
You can order it iced or as a Frozen Chiller, in Small, Medium or Large.
What does it taste like?
Bright, zesty and tart, like an orange soda with a squeeze of lime. It is refreshing on a hot day.
Calories by size
| Version | Small | Medium | Large |
|---|---|---|---|
| Iced | 180 | 230 | 350 |
| Frozen Chiller | 150 | 180 | 290 |
A Large iced Heatwave has 350 calories.
Sugar by size
| Version | Small | Medium | Large |
|---|---|---|---|
| Iced | 44 g | 57 g | 88 g |
| Frozen Chiller | 36 g | 44 g | 72 g |
How much caffeine does it have?
| Version | Small | Medium | Large |
|---|---|---|---|
| Iced | 67 mg | 105 mg | 133 mg |
| Frozen Chiller | 36 mg | 55 mg | 71 mg |
Flavor syrups take up space in the cup, so a flavored 7 Energy has a little less caffeine than the plain base. The Frozen Chiller has about half, because ice replaces part of the drink. The U.S. FDA says up to 400 mg a day is generally safe for most healthy adults.
Sugar-free and lighter options
You can ask for the Sugar-Free 7 Energy base, which has 0 to 10 calories on its own. The Heatwave syrups add sugar, so ask whether your stand has sugar-free versions of each flavor.
Allergens
The official guide lists no top 9 allergens for the Heatwave. Adding cream, cold foam or a chocolate drizzle adds milk, and cold foam also lists soy. Cross-contact is possible at any stand, so tell the barista about serious allergies. See the full allergen guide.
How much does a Heatwave cost?
A Small Heatwave costs about $6.83, a Medium about $7.91 and a Large about $9.43. 7 Brew does not publish prices, so these are estimates.
| Size | Price |
|---|---|
| Small | $6.83 |
| Medium | $7.91 |
| Large | $9.43 |
These are estimated prices reported by 7brewcoffemenus.com in October 2026. 7 Brew does not publish prices, and each stand sets its own, so your stand may charge more or less. Check the menu board before you order.
How it compares
In a Large, the Heatwave is tied for the lightest of these 7 Energy flavors:
| Drink (Large) | Calories | Sugar |
|---|---|---|
| Tropic Thunder | 350 | 88 g |
| Heatwave | 350 | 88 g |
| Brewberry | 350 | 87 g |
| Pixie Stick | 350 | 86 g |
| Nightshade | 350 | 88 g |
| Ocean Breeze | 360 | 91 g |
| Sunrise | 360 | 88 g |
Order it if you like citrus drinks. It is less sweet-tasting than the berry flavors.
How to order and customize it
Say the size, the name and the style: “Medium Heatwave, iced.” Then add changes. The official menu lists these options:
- Sweetness: 1/4, 1/2, regular or extra.
- Toppings: cream, whipped cream, cold foam, or a white chocolate, dark chocolate or caramel drizzle.
- Extra flavors: add any syrup on the menu, and many come sugar-free.
