What Is a Cooler?

A cooler is one of the most versatile categories of refreshing drinks. Traditionally, coolers were created to help beat the heat, combining fruit, herbs, citrus, tea, or sparkling water into light, thirst-quenching beverages. Today, they can be either alcoholic or non-alcoholic and may be served still or sparkling.

If you’re a fan of virgin mojitos, this cooler offers a similarly refreshing combination of mint, citrus, and bubbles, with rhubarb adding a delicious sweet-tart twist.

Traditional Coolers

Classic coolers often feature:

Fresh fruit for natural flavour.
Herbs such as mint or basil.
Citrus juice for brightness.
Still or sparkling water for refreshment.
Plenty of ice to keep everything crisp and cold.

Cooler vs. Other Summer Drinks

While these drinks sometimes overlap, each has its own personality.

Cooler. A broad category of refreshing drinks that often combines fruit, herbs, and either still or sparkling water. This Rhubarb Mint Cooler is a perfect example.
Fizz. Typically more citrus-forward and built around sparkling water. If you enjoy bubbly drinks, my Rhubarb Citrus Fizz offers another refreshing way to use homemade rhubarb syrup.
Lemonade. Usually made with lemon juice, sweetener, and water, giving it a stronger citrus profile.
Spritz. Traditionally made with sparkling wine and a bitter aperitif, although modern alcohol-free versions have become increasingly popular.
Cream Soda. Sweeter and creamier, usually focusing on flavoured syrup and vanilla rather than herbs or citrus.

No matter which style you prefer, they’re all wonderful ways to stay cool throughout the summer.

Why Rhubarb and Mint Work So Well Together

Some flavour combinations become classics for good reason.

Rhubarb is naturally tart and fruity, while mint contributes a cooling freshness that makes the overall drink feel even lighter. Lime acts as a bridge between the two, adding brightness without overwhelming either ingredient.

Together, they create a drink that’s refreshing, balanced, and ideal for warm weather.

Ingredients You’ll Need For This Rhubarb Cooler with Lime and Mint

It doesn’t take much to make this sparkling summer drink.

Rhubarb syrup. Homemade or store-bought. How to Make Rhubarb Syrup (Less Sweet, Perfect for Cocktails)
Fresh mint. Spearmint is my preferred choice because of its gentle sweetness.
Fresh lime juice. Adds brightness and balances the syrup.
Sparkling water or club soda. For plenty of refreshing bubbles.
Ice. Lots of it!
Optional garnish. Mint sprigs, lime slices, edible flowers, or thin ribbons of rhubarb.

Easy Variations

Once you’ve mastered the basic rhubarb cooler with lime and mint, it’s easy to experiment.

Swap lime for lemon if you prefer brighter citrus notes.
Turn it into a mojito-inspired cooler by adding extra mint and lime for a drink reminiscent of a refreshing virgin mojito.
Try grapefruit for a softer, slightly bittersweet finish.
Add cucumber slices for extra freshness.
Use basil instead of mint for a different herbal twist.
Stir in a little fresh ginger for gentle warmth.
Replace sparkling water with still water for a quieter, equally refreshing cooler.

Sparkling Water or Still Water?

Both versions are delicious, so the choice comes down to the kind of drink you’re craving.

Sparkling water or club soda creates a light, bubbly cooler that’s perfect for hot summer days.
Still water produces a softer, more delicate drink that’s equally refreshing and lets the rhubarb and mint take centre stage.
Club soda has added minerals that create a slightly sharper flavour, while sparkling water tends to taste cleaner and more neutral.

Whichever you choose, use well-chilled water and plenty of ice for the most refreshing results.

I Don’t Have Rhubarb Syrup. What Other Coolers Can I Make?

No rhubarb syrup? Don’t worry! The same simple idea works beautifully with other homemade syrups, preserves, or even fruit jams.

Some delicious alternatives include:

Rose Cooler with rose syrup and lemon.
Lavender Cooler with lavender syrup and fresh citrus.
Cherry Mint Cooler made with cherry syrup.
Watermelon Cooler for a light and fruity summer drink.
Passion Fruit Cooler with lime and sparkling water.

You can even use jam instead of syrup.

Apricot Jam Cooler

Simply whisk a spoonful of smooth jam with a splash of warm water until dissolved before adding ice and sparkling or still water. It’s a wonderful way to use homemade preserves while creating an entirely new summer drink.

Can I Make a Large Batch?

Absolutely! This Rhubarb Mint Cooler is perfect for entertaining.

Simply multiply the rhubarb syrup, lime juice, and mint by the number of servings and combine them in a large pitcher. Refrigerate until well chilled, then add plenty of ice and pour in the sparkling water just before serving to preserve the bubbles.

Finish the pitcher with extra mint sprigs, lime slices, and, if desired, thin ribbons of rhubarb for an attractive presentation.

How to Make This Cooler with Rhubarb Syrup and Mint Boozy

Although this cooler is designed as a refreshing non-alcoholic drink, it’s easy to transform it into a light summer cocktail.

Some spirits pair especially well with rhubarb and mint:

Gin. My favourite option, especially botanical or floral styles.
White rum. For a mojito-inspired variation with refreshing mint and lime flavours.
Vodka. A clean, neutral choice that lets the rhubarb remain the star.
Blanco tequila. Crisp, citrusy, and surprisingly refreshing with rhubarb.

Start with about 1½–2 oz (45–60 ml) of your preferred spirit per serving, then adjust the rhubarb syrup and lime juice to taste.
