Top up with sparkling water, stir once, and garnish with a sprig of mint and a wedge of watermelon.

Why summer drinks are long
Summer drinks are almost always long drinks, and that is no coincidence. In warm weather, you drink faster, and a short cocktail of 8 cl with forty percent alcohol is not a good idea. By stretching the same amount of drink with juice, soda, and plenty of ice, you hold the same glass for longer and it stays cold until the last sip. The second reason is flavor: fresh fruit and citrus need room to unfold. A Mojito in a small glass is simply a different drink.
The right glass
A long drink glass of 35 to 47 cl is the workhorse of summer: tall enough for a full load of ice, narrow enough to retain carbonation. Choose a straight-sided model rather than a tapered glass, because straight sides keep the ice cubes in place so they melt more slowly. Thick bases also help by keeping the warmth of your hand away. For the tropical side of the season, such as a Piña Colada, choose a wider glass from our hurricane glasses.

The right tools
For summer cocktails, besides the glass, use a Boston shaker, a jigger for precise measuring, a cocktail strainer, a fine strainer for double straining and a citrus press. These are the bar tools we use ourselves; you can find everything in our bar tools & cocktail sets.

Variations & twists
Watermelon is easy to replace: strawberry, peach, or melon work in the same proportions. Swap the rum for gin and the cooler becomes more herbal; with tequila, you get a salty undertone that pairs well with watermelon. If you want it without bubbles, leave out the sparkling water and shake everything briefly. You will have a smaller, more intense glass. For a version with fruit only, see the watermelon cocktail.
Servingtip
Put the glasses in the freezer for half an hour and fill them to the brim with ice. Filling them halfway actually makes the ice melt faster. Cut the fruit only when the guests arrive; watermelon loses its aroma within an hour and then becomes watery around the edges.
Good to know
Ice does most of the work
In refreshing cocktails, ice does more work than the drink itself. A full glass of ice melts more slowly than a half-full glass because the cubes keep one another cold; so anyone trying to save ice actually ends up with a lukewarm, watered-down cocktail. Use large cubes in the glass and smaller ones in the shaker, because there you do want some melting. Make the ice with filtered water and keep it covered, otherwise it will absorb the smell of your freezer. And top it up as soon as the glass is half empty.
What you find under summer cocktails
If you search for summer cocktails, you'll find roughly three groups. The first is the fruit sour: rum or gin, citrus, syrup, and fresh fruit, shaken and poured over ice. The second is the spritz family, where bubbles do the work and you barely need to measure anything. An Aperol Spritz belongs there. The third is the tropical category with coconut and pineapple, with the Piña Colada as its best-known example. All three work outdoors, provided you have enough ice.
Shaken with fresh fruit
Fresh fruit in the shaker requires two things: shake hard and then strain. Purée soft fruit first and strain the juice; otherwise pulp will remain and float on top of your cocktail. Don't muddle mint with a muddler; press it once between your hands instead, releasing the oils without bruising the leaves. Measure with a jigger, especially syrup, because half a centiliter too much is immediately noticeable with fruit. You'll find our cocktail shakers together, with bar spoons and strainers beside them.
Alcohol-free yet full-bodied
An alcohol-free cooler needs something extra, otherwise it remains lemonade. Replace the rum with 4 cl of strong chilled tea or alcohol-free rum, and keep the citrus and syrup the same. The acidity does most of the work. A pinch of salt makes fruit taste rounder and mimics the body that alcohol normally provides. Our Virgin Mojito follows the same principle, and the overview of mocktails gives you more recipes for those who don't drink. Serve them in the same glass as the rest, and no one will notice the difference.
For a whole garden
Outdoors, you rarely pour just one glass, so a pitcher is more practical than a shaker. Anything without bubbles can be mixed in advance: spirits, syrup, and juice in the recipe's proportions multiplied by six, in a sealed pitcher in the refrigerator. Squeeze fresh citrus on the day itself, as it loses its freshness within a day. Add ice and sparkling water only to the glass; otherwise, you'll have lukewarm water after half an hour. Put a pitcher of water next to it and stick to one or two glasses per guest.
Four recipes for the season
The four below cover the summer. The Mojito is the most requested: rum, mint, lime and soda, and it only works with fresh mint. The Aperol Spritz is the lightest and easiest for a group. The watermelon cocktail is closest to the cooler above, and the Piña Colada is the only one you blend. Start with the Mojito; it teaches you the most about balance. If you have a mixed group, make two with alcohol and two without; the proportions remain the same.
Frequently asked questions
Which refreshing cocktails are suitable for warm weather?
Long drinks with plenty of ice and citrus: a Mojito, a Paloma or the cooler above. What they have in common is a low alcohol ratio per glass and a generous dose of acidity, because acidity feels cooler than sweetness. Avoid cream and heavy liqueurs; they feel heavy once the temperature rises above twenty degrees.
Which glass do you use for summer cocktails?
A 35 to 47 cl highball glass for almost everything: tall, straight and with room for a full load of ice. View our highball glasses. For tropical cocktails with coconut or pineapple, use a wider glass, and for a spritz, a large wine glass.
Can you make summer drinks in advance?
Anything without bubbles or ice can be mixed up to a day in advance and stored covered and chilled. Add fresh citrus on the day itself. Ice, sparkling water and garnish belong in the glass, not in the pitcher; otherwise, within half an hour you'll be serving lukewarm cocktails.
How much watermelon do you need for 6 cl of juice?
Approximately 150 grams of flesh without the peel or seeds. Briefly purée it and strain it through a fine sieve; what remains is clear pink juice. Half a medium-sized watermelon yields enough for a pitcher of six glasses. The juice keeps for a day in the refrigerator, after which it loses its aroma.
