What you need
Ingredients for the 7 Brew Brew Lagoon Recipe
Here is everything you need for this 7 Brew Brew Lagoon 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.
- Sparkling water: 1 cup (8 oz) (club soda works too)
- Lime syrup: 1/4 oz (1/2 tbsp) (or 1 tbsp fresh lime juice)
- Blue raspberry syrup: 1/2 oz (1 tbsp) (sweet and blue)
- Coconut syrup: 1/4 oz (1/2 tbsp) (tropical finish)
- Ice: 1 to 1 1/2 cups (crushed or nugget ice works best)
Tip: Freeze blue raspberry syrup mixed with water in an ice tray. The blue ice cubes keep the color bright as they melt.

How to Make a 7 Brew Brew Lagoon at Home
A 7 Fizz is an Italian-style soda, so it only takes a few steps. The syrups go in first, then the ice, then very cold sparkling water. Stir gently so the bubbles stay. Add a splash of cream at the end if you like it creamy. It takes about five minutes.
- Add the syrups: Pour the lime syrup, blue raspberry syrup and coconut syrup into a tall 16 oz cup.
- Fill with ice: Add about 1 1/2 cups of crushed ice.
- Add sparkling water: Pour in cold sparkling water slowly.
- Stir and top: Stir gently, then add 2 tbsp of cream if you want it creamy.
Pro tips for the best taste
- Use cold ingredients so the ice melts slowly.
- Measure syrups the first time, then adjust to taste.
- Stir from the bottom, because syrup sinks.
- Store syrups in a cool, dark spot so they last.
Stir gently to keep the bubbles. If the drink tastes flat, use fresher sparkling water. A lime wheel on the rim looks great. For a creamy version, add two tablespoons of half-and-half. It turns a soft pastel blue.
