Quick summary
“This refreshing drink combines a full-bodied double espresso with chilled sparkling water and an artisanal syrup flavored with spices and citrus fruit peels. Served in distinct layers over ice cubes, it delivers lively effervescence and sophisticated aromatic notes.”
What you need to know
- The homemade syrup boiled with citrus peels, cloves, and cinnamon recreates botanical notes of the classic cola drink without chemical dyes.
- The prior cooling of the espresso coffee prevents the accelerated melting of the ice and the consequent loss of gas from the mineral water.
- The careful addition of espresso over the sparkling water creates a clear visual gradient before the final mixing with a straw.

Instructions
Principal
- Prepare the citrus cola syrup: In a small saucepan, combine 100ml of water, 100g of sugar, orange and lemon zest, clove, cinnamon, and, if using, cola essence. Bring to medium heat until it boils and the sugar dissolves completely. Let it simmer for 5 minutes over low heat to infuse the flavors, then strain and cool completely in the refrigerator. This concentrated syrup is the heart of our drink and can be made in advance.
- In simple terms: Ensure the espresso is perfectly chilled before starting assembly to preserve the integrity of the drink. A good espresso extraction is fundamental for the final flavor and to avoid excessive bitterness. The professional technique is to cool the coffee quickly.
- Fill a tall glass with ice, almost to the rim. The most common mistake is using too little ice, diluting the drink quickly. The ice should maintain the temperature and effervescence without compromising the flavor. The most important tip is the generous amount of ice.
- In the glass with ice, add 60ml of the chilled citrus cola syrup, distributing it evenly. Then, slowly pour in the 150ml of sparkling water. This creates an aromatic effervescent base that will be the foundation of your cocktail. The short answer is: mix the glue base well.
- Carefully, pour the 120ml of chilled double espresso over the cola and sparkling water mixture, allowing it to settle in distinct layers. This visual effect is as important as the flavor. The secret of this recipe is patience to create the perfect layers.
- Decorate with a slice of orange or lemon on the rim of the glass and a few fresh mint leaves. If desired, add some coffee beans on top for extra aroma and a sophisticated presentation. Serve immediately and enjoy the complexity of the flavors.
Chef's tips
- Use only the outer part of the citrus peel when making zest, avoiding the white pith which imparts bitterness.
- Fill the tall glass with plenty of hard ice to the rim to ensure the liquid stays at the lowest possible temperature.
- Pour the sparkling water and espresso slowly over the back of a bar spoon to preserve the effervescence and layers.
Variations
- Add a fresh sprig of rosemary lightly macerated in the glass to introduce a herbaceous and woody nuance to the drink.
- Add a teaspoon of fresh Rangpur lime juice to the syrup to increase the acid profile and citrus complexity.
- Finish with a pinch of freshly grated nutmeg over the creamy espresso foam on top of the tall glass.
Substitutions
- Traditional espresso coffee can be replaced by 80 ml of very concentrated French press coffee or dense cold brew.
- Sparkling water can be replaced by artisanal tonic water if you enjoy bitter notes of quinine in the cocktail.
- The refined sugar in the syrup can be replaced by demerara sugar, maintaining the same weight ratio for boiling.
How to store
The citrus cola syrup can be stored in a closed glass bottle in the refrigerator for up to 15 days. The drink must be assembled at the time of serving.
Can it be frozen?
Do not freeze the assembled cocktail. You can freeze the citrus syrup in ice cube trays to thaw on demand.
What to serve with
Pairs with buttery cinnamon cookies, warm apple pies, toasted nuts, or as an invigorating afternoon digestive.
Frequently asked questions
Should the drink be served mixed or with visible layers?
Present at the table with the layers separated to value the contrast of densities, mixing with a straw before the first sip.
What is the best coffee roast for this type of iced drink?
Medium or light roast coffee beans that present citrus and floral notes harmonize better with the gaseous effervescence.
How to prevent espresso coffee from losing the crema when cooling?
Extract the coffee directly over a pre-chilled metal cup or use a quick cooling method in an ice water bath.
Can I use commercial cola soda instead of the artisanal syrup?
It can be used, but the mixture becomes much sweeter and artificial; the homemade spice syrup highlights the clean bitterness of the coffee.
