A Watermelon Whiskey Sour is the kind of cocktail that instantly feels like summer. It’s refreshing, slightly sweet, and has just the right amount of tartness to keep things balanced. The combination of juicy watermelon and smooth whiskey makes this drink a crowd-pleaser, whether you’re sipping it on a warm evening or mixing up a batch for friends.
Watermelon Whiskey Sour
I’ve made this cocktail countless times, and it never fails to impress. Let’s walk through how to make it perfectly every time.
Ingredients
Makes 1 cocktail | Prep Time: 5 minutes
You’ll need:
- 2 oz (60ml) whiskey – A good bourbon works well for its smooth, slightly sweet flavor
- 1 oz (30ml) fresh watermelon juice – Blend fresh watermelon and strain out the pulp for the best taste
- 0.5 oz (15ml) fresh lemon juice – Adds that perfect tangy kick
- 0.5 oz (15ml) simple syrup – Adjust to taste for sweetness
- Ice cubes – For shaking and serving
- Watermelon slice or lemon twist – For garnish
Glass recommendation: An Old Fashioned glass works best, but a Mason jar gives it a fun, rustic touch.
How to Make a Watermelon Whiskey Sour
- Fill a cocktail shaker with ice.
- Pour in the whiskey, watermelon juice, lemon juice, and simple syrup.
- Shake well for about 15 seconds, until the shaker feels cold.
- Strain into an ice-filled glass.
- Garnish with a slice of watermelon or a lemon twist.
That’s it! A smooth, refreshing cocktail ready in minutes.
Helpful Tips
- Use fresh watermelon juice – Store-bought juice can be too sweet or lack freshness. Blending fresh watermelon and straining it makes a big difference.
- Adjust the sweetness – If you like a less sweet cocktail, reduce the simple syrup or swap it for honey.
- Chill your glass – A cold glass keeps the drink crisp and refreshing longer.
I’ve found that shaking this cocktail just a little longer than usual helps blend the flavors beautifully. It also gives it a nice, slightly frothy texture.
Variations to Try
Smoky Watermelon Whiskey Sour
- Add a pinch of smoked salt or use smoked watermelon juice for a deeper, smoky twist.
Spicy Watermelon Whiskey Sour
- Muddle a slice of jalapeño in the shaker before adding the ingredients for a little heat.
Watermelon Whiskey Sour Slushie
- Blend the ingredients with extra ice for a frozen version that’s perfect for hot days.
Non-Alcoholic Version
- Skip the whiskey and mix watermelon juice, lemon juice, and simple syrup with ice. Garnish with mint for a refreshing mocktail.
What to Serve With It
This cocktail pairs well with summer-friendly dishes:
- Grilled Chicken – The smoky char of grilled chicken complements the whiskey’s warmth.
- Spicy Appetizers – The watermelon’s sweetness balances the heat from spicy foods.
- Feta & Arugula Salad – A fresh, salty, and slightly peppery salad enhances the cocktail’s lightness.
The contrast of flavors makes every sip even more enjoyable!
Common Questions
Can I make this without a cocktail shaker?
Yes! Just stir everything well with ice in a glass, though shaking gives it a slightly frothy texture.
How do I store leftover watermelon juice?
Keep it in an airtight container in the fridge. It stays fresh for about 2 days.
What’s the best whiskey to use?
A smooth bourbon works best, but rye whiskey gives it a spicier kick if you prefer.
Can I make this in a large batch for a party?
Absolutely! Just multiply the ingredients by the number of servings and mix in a large pitcher.
Is there a lower-sugar option?
You can swap simple syrup for honey, agave, or a sugar-free sweetener.
How can I make it look extra fancy?
A watermelon wedge on the rim or a sprig of mint adds a nice touch. You can also rim the glass with sugar or salt for extra flavor.
This Watermelon Whiskey Sour has been my go-to cocktail for summer nights, and I hope it becomes one of yours too. It’s simple, refreshing, and always a hit. Cheers! 🍉🥃
