Watermelon Cocktail Ideas: Why This Summer Ingredient Deserves More Attention

Summer beverages typically feature ingredients that have a natural sweetness, light texture, and acidity in a balanced manner. No surprises then that watermelon is a quintessential summer fruit that can also be used as a cocktail ingredient. The fruit’s high water content gives watermelon drinks a light texture, while the subtle sweetness complements a wide variety of ingredients, such as herbs, citrus, spices, and sparkling mixers. Watermelon can be added as a mixer, garnish, or even infused into water to be adapted into a range of alcoholic and non alcoholic cocktails. It alters the final flavour and structure without masking the other ingredients or obstructing the character of the spirit.

Unlike cocktails made with dense tropical fruits such as mango and banana, watermelon cocktail recipes add an array of different flavours but remain lighter in structure. The subtle sweetness of watermelon, when mixed with other ingredients, adds layers of flavour without overloading the mixture. 

Some common ingredients that work well with watermelon:

• Lime imparts sharpness through its acidity

• Basil and mint offer herbal flavours and aroma

• Sparkling wine expands the watermelon flavour across the glass without making the drink too sweet and syrupy

Fresh watermelon juice creates the foundation for frozen cocktails, while remaining sufficiently thin for spritz cocktails. This versatility is why so many bartenders incorporate watermelon cocktails into their warm-weather menu; they can be served with a crisp finish as opposed to being served as a creamy or dessert-like beverage.

Watermelon cocktails also provide a unique opportunity to experiment with a wide range of spices. For example, using black pepper, ginger, jalapeno, or chaat masala in conjunction with watermelon allows for contrasting flavour profiles that complement each other.

Due to its high water content, watermelon can also be added to the Frozen Margarita cocktail and its variations. When combined with lime juice, tequila, and carbonated water or club soda, you will have a less acidic cocktail that can be served at garden parties, brunches, or get-togethers in summers. 

Here are some common flavour combinations to try:

• Watermelon with pink salt or lime zest provides a mineral-like sharpness

• Watermelon with jalapeno offers a sweet-and-spicy combination and grassy flavour notes

• Watermelon with basil adds complex savoury herbal notes

• Watermelon with grapefruit adds a dry citrus and bitter contrast to one another

Frozen Watermelon Margarita cocktails made with Don Julio Blanco (or any other tequila of your choice) often contain vegetal agave notes underneath the fruit, preventing it from being overly sweet. In addition to taste, texture is very important. A properly Frozen Watermelon Margarita cocktail should be made with crushed ice and little to no added sugar syrup if it is going to remain true to the produce’s natural moisture levels.

Spritz-style cocktails favour ingredients suitable for dilution. Watermelon, used as juice and mixed with sparkling wine or soda, yields a very fine or light aroma in spritzes. Typically, a spritz-style watermelon cocktail contains:

• Freshly made watermelon juice or clarified watermelon water

• Citrus juices for acidity

• Sparkling wine or soda for the drink’s body

• Cilantro or mint as an aromatic herb

Compared to other berry-based spritz cocktails, the watermelon spritz cocktail is much lighter, and the fruit flavour is less pronounced in the drink. Bartenders may use a smooth gin, like the Tanqueray No. Ten Gin, to pair with watermelon. Here, the gin's citrus-forward profile complements the fruit's sweetness while holding up to the effervescence.

You can try using watermelon with whisky in a highball cocktail, but you need to balance the flavours carefully. Watermelon cocktails work with whiskies that have some vanilla, toasted grain, and/or light spice character. A whisky-watermelon cocktail can be made with the following ingredients:

• Watermelon juice

• Citrus peel oil

• Ginger or black pepper

• Soda water

• Light whisky base 

Blended Scotch expressions such as Johnnie Walker Blonde create a smoother grain-forward profile against watermelon’s subtle sweetness. The ginger adds nuance to the drink, while soda water adds texture.

Due to watermelon’s ability to add body to drinks without the use of dairy, flavoured syrups, and excess sugar, non alcoholic cocktails made using watermelon are becoming more popular. It also helps that watermelon is an easy ingredient to pair with a wide variety of components, from tonic, kombucha, and green tea, to even coconut water.

Some popular non alcoholic cocktails featuring watermelon are:

• Watermelon Basil Cooler

• Watermelon Ginger Shrub

• Watermelon Mint Soda

• Watermelon Lime Sparkler

These flavour pairings tend to be less sweet, with a greater focus on the texture and acidity. The addition of basil lends the cooler a prominent savoury characteristic, the ginger adds a sense of complexity to the shrub, and the lime brings out the natural sweetness of the watermelon in the sparkler.

Watermelon may be a recognisable summertime fruit, but cocktail menus typically do not make use of this fruit as much as berries, mangoes, or passionfruit. However, the versatility of watermelon allows it to be adapted to a wide range of beverages while also complementing various flavour groups. The delicate, natural sweetness from watermelon lends itself well to building flavour, such as layering with herbs, spices, citrus, and carbonated ingredients. 

It’s time that those who experiment with seasonal flavours explore watermelon in drinks – it has myriad uses beyond being converted into a juice.
