What Is in a 7 Brew Heatwave?
Quick answer: The 7 Brew Heatwave is a 7 Energy drink flavored with orange, lime and lemon. It is one of the most tart and citrusy drinks on the menu.
If you love sour candy or citrus soda, the Heatwave is for you. Orange gives it a sweet base, while lime and lemon add a sharp, tangy bite. The three citrus flavors make it taste clean and fresh. A Large flavored 7 Energy has about 133 mg of caffeine. 7 Brew also sells a Heatwave Lemonade with the same flavors and no caffeine.
The Heatwave is a great summer drink, because citrus feels cooling on a hot day. It is also less sweet than many other energy flavors. At home, you can use fresh lime and lemon juice instead of syrups. That makes it taste even brighter. Just add a little simple syrup if it gets too sour.

Ingredients for the 7 Brew Heatwave Recipe
Here is everything you need for this 7 Brew Heatwave recipe. It makes one 16-ounce drink, which is close to a 7 Brew Small. Use coffee-shop style syrups and sauces, the same kind sold for lattes and Italian sodas. A pump from a store syrup bottle is about 1/4 ounce, and a tablespoon is about 1/2 ounce. Change the amounts after your first try to match your taste.
| Ingredient | Amount | Notes |
|---|---|---|
| Energy drink | 1 can (8.4 to 12 oz) | Sugar-free works well |
| Orange syrup | 1/2 oz (1 tbsp) | Sweet citrus base |
| Lime syrup | 1/4 oz (1/2 tbsp) | Or 1 tbsp fresh lime juice |
| Lemon syrup | 1/4 oz (1/2 tbsp) | Or 1 tbsp fresh lemon juice |
| Ice | 1 to 1 1/2 cups | Crushed or nugget ice works best |
Tip: Fresh citrus juice makes this drink pop. Squeeze half a lime and a lemon wedge right into the cup.
Step by step
How to Make a 7 Brew Heatwave at Home
Energy drinks are the easiest 7 Brew drinks to copy. Put the syrups in first so they mix with the bubbles. Then add ice and pour the cold energy drink slowly. A gentle stir keeps it fizzy. You will be done in about five minutes.
- Add the syrups: Pour the orange syrup, lime syrup and lemon syrup into a tall 16 oz cup.
- Fill with ice: Add about 1 1/2 cups of crushed or nugget ice.
- Pour the energy drink: Slowly add a cold energy drink so it does not fizz over.
- Stir and enjoy: Stir gently and drink right away while it is cold.
Taste before you add more syrup, because citrus can get sour fast. A pinch of salt on the rim makes it taste like a fun summer drink. Use crushed ice for a slushy feel. For a frozen Heatwave, blend it with two cups of ice. Add orange slices for color.
