Watermelon Sour Cocktail
Sweet, tart, and undeniably fresh - my Watermelon Sour Cocktail is everything you want in a summer drink. Made with muddled watermelon chunks, tequila, a splash of lime juice, and a touch of simple syrup, it's a thirst-quenching cocktail that highlights the bold, juicy flavor of summer's most popular fruit.
Think of it as a twist on a classic sour cocktail, but lighter and more playful. It's the kind of drink you want to sip slowly on a patio, preferably with a wedge of fresh watermelon in hand.
Made in a cocktail shaker with just a few ingredients, this is an easy cocktail with major flavor - perfect for those who want something crisp, bright, and not overly sweet.

Frequently Asked Questions About Watermelon Sour Cocktails
Do you have questions about making our watermelon sour?
Yes, but you may want to reduce or skip the simple syrup - packaged juice is often sweeter.
A clean silver or blanco tequila works best to let the watermelon shine.
You can multiply the ingredients and pre-muddle the watermelon chunks in a pitcher, but wait to shake or stir until serving for best flavor.
It's ideal for chilling and mixing, but a mason jar with a tight lid can work in a pinch.
This cocktail leans more tart and citrusy than sweet - it's inspired by the classic sour cocktail formula of equal parts spirit, citrus, and sweetener.
