If you’re craving a drink that screams summer, the Watermelon Sour is just what you need. Sweet, juicy watermelon meets a tangy splash of lemon in this super-refreshing cocktail that’s perfect for sunny afternoons or backyard barbecues. I’ve made this countless times, and it’s always a crowd-pleaser—simple to make, yet so impressive. Let’s get started!
Watermelon Sour
Ingredients
You’ll need the following (makes 1 serving):
- Watermelon Juice: 3 oz (90 ml) – fresh is best for that vibrant flavor!
- Lemon Juice: 1 oz (30 ml) – freshly squeezed for a zesty punch.
- Simple Syrup: 0.5 oz (15 ml) – or swap with honey or agave for a natural sweetener.
- Vodka: 2 oz (60 ml) – or gin for a more botanical vibe.
- Ice: A handful
- Watermelon Slice or Mint: For garnish
Prep Time
- Prep Time: 5 minutes
- Servings: 1 cocktail
Method
- Start by adding the watermelon juice, lemon juice, simple syrup, and vodka into a cocktail shaker.
- Toss in a handful of ice and shake it up until the mixture is nice and cold—about 15 seconds.
- Strain the drink into a rocks glass filled with ice. If you don’t have a rocks glass, a highball glass works too.
- Finish it off with a garnish: a fresh slice of watermelon or a sprig of mint adds a fun, summery touch.
Serve immediately and enjoy the cool, sweet-tangy magic. Pro tip: If you’re making this for a party, you can prep the juice mix ahead of time, but don’t add the ice or shake until just before serving to keep it fresh and chilled.
Tips for the Best Watermelon Sour
- Use fresh watermelon juice. It’s easy to make—just blend chunks of watermelon and strain out the pulp. Store-bought works in a pinch, but fresh really makes the drink shine.
- Adjust the sweetness. If you like it less sweet, cut back on the simple syrup or use a natural sweetener like honey.
- Play with garnishes. Mint sprigs, lemon wheels, or even a salted rim can elevate the look and taste.
Serving Suggestions
Pair your Watermelon Sour with light, summery dishes to keep the vibe going. Here are some of my favorite combos:
- Grilled Chicken: The smoky, savory flavors balance the cocktail’s sweet and tangy notes.
- Shrimp Cocktail: A cool, refreshing match for the citrusy punch of the drink.
- Fruit Salad: Berries, pineapple, and melon make a great sidekick for this juicy cocktail.
Variations to Try
Once you’ve nailed the classic Watermelon Sour, have fun experimenting!
Mint Watermelon Sour
- Add a few fresh mint leaves to the shaker and muddle them with the watermelon juice before adding the rest of the ingredients. It’s like a mojito and sour had a baby!
Spicy Watermelon Sour
- Toss in a slice of fresh jalapeño when shaking for a subtle kick of heat that complements the sweetness.
Coconut Watermelon Sour
- Swap out the simple syrup for coconut water. It’s lighter, hydrating, and gives the drink a tropical twist.
Virgin Watermelon Sour
- Skip the vodka and you’ve got yourself a refreshing mocktail that’s just as delicious—perfect for kids or non-drinkers.

Storage Tips
If you’ve got leftover juice mix, store it in an airtight container in the fridge for up to 24 hours. Just give it a good shake before using. Once mixed with alcohol and ice, though, it’s best enjoyed right away.
