Refreshing watermelon cocktail

I recently had the pleasure of experiencing a relaxing long weekend in Cabo San Lucas. I sampled more than a few delicious adult beverages while I was there, but my favorite was the watermelon cocktail with fresh herbs from Flora Farms.

It was light and refreshing, and not too strong or too sweet, which is exactly what I look for in a summer cocktail. I knew I'd be making it at home ASAP.

Thanks to the availability of fresh cold pressed watermelon water or watermelon juice at most grocery stores (or the ease of making your own), it was super simple to re-create the recipe.

What kind of watermelon juice to use

If you prefer, you can make your own watermelon juice for this drink, but I find it a lot easier to buy it pre-made at the store.

Fresh watermelon juice can be on the pricey side, but you don't need to use much in this cocktail, so a little goes a long way. Plus, it's very hydrating, which is an added bonus if you're enjoying this cocktail on a hot summer day.

If you want to make your own watermelon juice, you have a few options: you can blend watermelon in a blender (make sure to remove any hard seeds!) and then sieve or strain it through a coffee filter.

You can also muddle watermelon in a cup with a mojito muddler and then strain it the same way.

Watermelon and fresh herbs

The addition of fresh basil and fresh mint adds to the summery taste, and these herbs pair SO well with watermelon.

Use a muddler to get the most flavor out of the herbs.

What type of rum should I use?

The type of rum you use in this cocktail is important. Look for a clear rum labeled "light rum," "white rum," or "silver rum."

I love the light rum in this recipe because the taste is really mild (in fact I hardly tasted it at all). There's something about a summer cocktail with rum that just gives off an "instant vacation in a glass" vibe.

Avoid using gold rum or dark rum for this recipe, as the flavor will overpower the other ingredients.

  • 4 oz watermelon juice see notes
  • 2 oz light rum
  • 3 basil leaves
  • 3 mint leaves
  • ice

Special equipment


  • Using a muddler, a fork, or a spoon, smash the basil and mint leaves into the bottom of a glass to release their juices.
  • Add watermelon water, rum, and 2 oz water. 
  • Stir to combine. Fill the glass with ice, and serve.


Check the produce section of your grocery store for fresh-pressed watermelon juice.
To make your own watermelon juice, blend the red part of the watermelon in a blender (without any hard seeds), then strain it through a fine mesh sieve or through a coffee filter, depending on whether you want any pulp. Another option is to muddle cubes of watermelon in a glass and then strain out the solids and use the juice for this drink.
