A Sunset Rum Fizz is like sipping on a tropical breeze—light, citrusy, and just the right amount of fizzy. The mix of rum, fresh lime, and soda water makes it a refreshing go-to, whether you’re lounging by the pool or unwinding after a long day. I’ve made this drink countless times, and it never fails to bring a little sunshine to the moment. Let’s get into how to make this simple yet stunning cocktail.

Sunset Rum Fizz
Ingredients
You’ll need:
- 2 oz (60ml) white rum
- 1 oz (30ml) fresh lime juice
- 0.5 oz (15ml) simple syrup
- 2 oz (60ml) soda water
- 1 cup (240ml) ice
- Orange slice, for garnish
A highball glass works best for this drink, but a Collins glass is a great alternative.
How to Make a Sunset Rum Fizz
- Fill a highball glass with ice—this keeps everything crisp and chilled.
- Pour in the white rum, followed by the lime juice and simple syrup.
- Top it off with soda water—this gives it that light, fizzy finish.
- Give it a gentle stir (don’t overdo it, or you’ll lose the bubbles!).
- Garnish with a slice of orange for a pop of color and a hint of citrus aroma.
That’s it! Simple, fresh, and perfect for warm days.
Tips for the Best Sunset Rum Fizz
- Use fresh lime juice—bottled just doesn’t have the same brightness.
- Don’t over-stir—keeping the fizz lively is key.
- Want it a little sweeter? Add a splash more simple syrup or try honey for a natural touch.
- Looking for more fizz? Use extra soda water or swap it for a flavored sparkling water.
