A Watermelon Negroni is the ultimate summer cocktail—refreshing, slightly bitter, and bursting with juicy watermelon flavor. It takes the classic Negroni and gives it a fruity, vibrant twist that’s perfect for warm evenings. I’ve made this drink countless times, and trust me, it’s a crowd-pleaser at summer gatherings. The combination of gin, Campari, and sweet vermouth blends beautifully with fresh watermelon juice, creating a cocktail that’s both bold and refreshing.

Watermelon Negroni
Ingredients
You’ll need:
- 1 oz (30 ml) gin
- 1 oz (30 ml) Campari
- 1 oz (30 ml) sweet vermouth
- 2 oz (60 ml) fresh watermelon juice
- Ice (enough for shaking and serving)
- Watermelon slice, for garnish
How to Make a Watermelon Negroni
- Fill a cocktail shaker with ice.
- Pour in the gin, Campari, sweet vermouth, and watermelon juice.
- Shake well for about 15 seconds until the mixture is well chilled.

Tips for the Best Watermelon Negroni
- Use fresh watermelon juice. Bottled juice can work in a pinch, but fresh juice gives the best flavor. Just blend fresh watermelon and strain it for a smooth consistency.
- Chill your glass. A cold glass keeps your drink refreshing for longer.
- Adjust the sweetness. If you prefer a slightly less bitter cocktail, reduce the Campari a little or add a splash of simple syrup.

Watermelon Negroni Spritz

Food Pairings
This cocktail pairs beautifully with fresh, summery dishes:
- Grilled shrimp – The smoky, charred flavor contrasts nicely with the cocktail’s fruity bitterness.
- Caprese salad – Juicy tomatoes, fresh mozzarella, and basil bring out the sweetness in the watermelon.
- Prosciutto & melon – The salty, savory prosciutto balances the cocktail’s bright, fruity notes.
Make-Ahead & Storage Tips
- You can mix the ingredients (minus the ice) a few hours ahead and store in the fridge. Just shake with ice before serving.
- If you have leftover watermelon juice, store it in an airtight container in the fridge for up to 2 days.
