1. How to Make the Classic Espresso Tonic

Pin this simple recipe to your ‘Summer Drinks’ board!

The classic espresso tonic recipe is the foundation for all other variations, offering a simple espresso tonic drink that highlights the inherent qualities of its few ingredients. The key to this refreshing coffee drink is the quality of your double shot espresso and your chilled tonic water. The tonic water enhances the espresso by adding a crisp bitterness and delightful effervescence, creating an invigorating beverage perfect for warm afternoons.

Ingredients

• 1 double shot espresso (2 oz / 60ml) freshly brewed, preferably a single-origin with fruity notes
• 5 oz (150ml) high-quality chilled tonic water, like Fever-Tree or Q Mixers
• Large, clear ice cubes
• 1 lemon or lime twist for garnish

Instructions

1. Fill a highball glass to the top with large ice cubes. Using large cubes prevents dilution of the drink.
2. Pour the chilled tonic water over the ice, leaving about an inch of space at the top.
3. Brew a fresh double shot espresso. For the best flavor, use your espresso machine to pull the shot right before making the drink.
4. Gently pour the hot espresso over the back of a spoon onto the tonic water to create a beautiful layered effect.
5. Garnish with a fresh lemon twist, expressing the oils over the top of the drink before placing it on the rim. Serve immediately.

Pro-Tip: The key to a great espresso tonic is temperature contrast. Pouring hot, freshly brewed espresso directly over very cold tonic and ice creates the best flavor and visual separation. Don’t let your espresso sit and cool down.

2. How to Make a Zesty Orange & Bitters Espresso Tonic

Save this citrusy coffee idea for your next brunch!

For a vibrant twist on the homemade coffee tonic, the Orange & Bitters Espresso Tonic introduces bright citrus notes that beautifully complement the espresso. This refreshing coffee drink utilizes fresh orange juice and aromatic orange bitters to brighten the coffee and balance the bitter notes of both the tonic and the espresso. It’s a popular variation that adds a layer of aromatic complexity to your simple espresso tonic.

Ingredients

• 1 double shot espresso (2 oz / 60ml) freshly brewed
• 4 oz (120ml) chilled premium tonic water
• 1/2 oz (15ml) fresh orange juice
• 2 dashes orange bitters
• Large ice cubes
• 1 dehydrated orange wheel for garnish

Instructions

1. Fill a highball glass with ice.
2. Add the fresh orange juice and orange bitters to the glass.
3. Pour in the chilled tonic water and give it a very gentle stir to combine.
4. Brew your double shot espresso.
5. Slowly pour the espresso over the tonic mixture.
6. Garnish by sliding a dehydrated orange wheel into the glass.

Pro-Tip: The citrus oil emulsion from a fresh orange peel can be even more impactful than the juice. Before garnishing, twist a fresh piece of orange peel over the drink’s surface to release its aromatic oils. This adds a wonderful scent and initial burst of flavor.

3. How to Make a Spicy Ginger & Lime Espresso Tonic

Need a kick? Pin this spicy coffee recipe!

For those seeking an adventurous and spicy coffee drink, the Spicy Ginger & Lime Espresso Tonic delivers a unique flavor combination. This espresso tonic recipe infuses the classic with the warming spice of ginger syrup and the sharp, acidic kick of fresh lime juice, transforming the coffee profile into something truly unexpected. It’s a refreshing summer drink that offers a lively zing, making it a favorite among those who enjoy bold flavors.

Ingredients

• 1 double shot espresso (2 oz / 60ml) espresso, preferably from a medium roast
• 4 oz (120ml) chilled premium tonic water
• 1/2 oz (15ml) ginger syrup
• 1/4 oz (7.5ml) fresh lime juice
• Large ice cubes
• 1 lime wheel for garnish

Instructions

1. Combine the ginger syrup and fresh lime juice at the bottom of a highball glass.
2. Fill the glass with ice cubes.
3. Pour in the chilled tonic water.
4. Brew your espresso shot.
5. Gently float the hot espresso on top of the tonic.
6. Garnish with a fresh lime wheel and serve.

Pro-Tip: For an extra layer of flavor, try using a spicy ginger beer instead of tonic water. This will make the drink less bitter from quinine and more pronounced in its ginger spice. Adjust sweetness as needed.

4. How to Make a Smoked Grapefruit & Rosemary Espresso Tonic

Elevate your coffee game. Pin this sophisticated recipe!

For those seeking unique espresso tonic variations with a sophisticated edge, the Smoked Grapefruit & Rosemary Espresso Tonic offers an advanced mixology for coffee experience. This recipe introduces the herbaceous aroma of rosemary, which complements the bitter notes of grapefruit and coffee, while a hint of smoke adds a twist of complexity. It’s a truly aromatic coffee blend, perfect for impressing guests or enjoying a quiet moment of elevated indulgence.

Ingredients

• 1 double shot espresso (2 oz / 60ml) espresso
• 4 oz (120ml) chilled elderflower tonic water (optional, but recommended)
• 1/2 oz (15ml) fresh pink grapefruit juice
• Large ice cubes
• 1 fresh rosemary sprig for garnish

Instructions

1. Fill your highball glass with large ice cubes and add the grapefruit juice.
2. Pour the chilled elderflower tonic water over the ice.
3. Brew your double shot espresso.
4. Gently pour the hot espresso over the tonic to create the layers.
5. Prepare Garnish: Using a culinary torch or a lighter, carefully scorch the tip of the rosemary sprig until it starts to smoke and becomes fragrant.
6. Garnish the drink with the smoking rosemary sprig and serve immediately to capture the aroma.

Pro-Tip: Understanding the tonic water quinine content is key here. Elderflower tonic is less bitter than Indian tonic, which allows the delicate flavors of grapefruit and rosemary to shine. If using standard tonic, you may want to add a tiny splash of simple syrup to balance the bitterness.

5. How to Make a Decadent Salted Cream Espresso Tonic

Your new favorite dessert coffee. Pin this creamy recipe!

For a truly decadent and unique coffee experience, the Salted Cream Espresso Tonic offers a luxurious twist on the traditional layered coffee drink. This variation balances the bitter notes of the coffee and tonic with a rich, slightly salty cream, creating a dessert-like experience. It’s a sophisticated answer for those who appreciate a creamy coffee drink but want to explore beyond the usual latte, demonstrating precision coffee crafting for an elevated taste.

Ingredients

• 1 double shot espresso (2 oz / 60ml) espresso
• 4 oz (120ml) chilled tonic water
• 2 oz (60ml) heavy whipping cream, very cold
• 1/4 tsp simple syrup (optional)
• Pinch of flaky sea salt, plus more for garnish
• Large ice cubes

Instructions

1. Prepare Cream: In a small bowl, combine the cold heavy cream, optional simple syrup, and a pinch of sea salt. Use a handheld milk frother to whip the cream until it’s thickened but still pourable, like melted ice cream. Set aside.
2. Assemble Drink: Fill a highball glass with ice and pour in the chilled tonic water.
3. Brew your espresso shot.
4. Pour the hot espresso over the tonic.
5. Top Off: Slowly and gently pour the prepared salted cream over the back of a spoon onto the espresso layer. It should float on top.
6. Garnish with an extra sprinkle of flaky sea salt.

Pro-Tip: The key to a perfect float is the specific gravity of the liquids. The cream must be whipped just enough to incorporate air, making it less dense than the coffee layer beneath it. Don’t overwhip, or you’ll have solid whipped cream.

6. How to Make a Sweet Cherry & Almond Espresso Tonic

A coffee that tastes like dessert! Pin this cherry almond recipe.

This sweet coffee drink, the Cherry & Almond Espresso Tonic, offers a delightful, customizable tonic experience by incorporating flavored syrups. The nutty amaretto syrup and sweet cherry juice soften the drink’s bitterness and create a flavor profile reminiscent of a classic dessert like Bakewell tart or a cherry cordial. This espresso tonic recipe is perfect for those who prefer a less bitter, more indulgent take on the refreshing coffee drink.

Ingredients

• 1 double shot espresso (2 oz / 60ml) espresso
• 4 oz (120ml) chilled tonic water
• 1/2 oz (15ml) amaretto-flavored syrup (non-alcoholic)
• 1/4 oz (7.5ml) juice from a jar of maraschino or Luxardo cherries
• Large ice cubes
• 2 maraschino cherries for garnish

Instructions

1. Combine the amaretto syrup and cherry juice in the bottom of a highball glass.
2. Fill the glass with ice.
3. Pour in the chilled tonic water.
4. Brew your shot of espresso.
5. Gently pour the espresso over the tonic. The syrups at the bottom will create a beautiful, deep red layer.
6. Garnish with two maraschino cherries on a cocktail pick laid across the rim of the glass.

Pro-Tip: For a boozy kick, you can substitute the amaretto syrup with 1 oz of actual Amaretto liqueur. This transforms the coffee mocktail into a true coffee cocktail, perfect for an after-dinner drink. Experts in flavor analysis recognize that the benzaldehyde compound, responsible for almond/cherry flavor, pairs exceptionally well with pyrazine compounds developed in roasted coffee.

7. How to Make a Simple Cold Brew & Tonic (No Espresso Machine Needed)

No espresso machine? No problem. Pin this easy recipe!

For an easy make drink that doesn’t require an espresso machine, the Simple Cold Brew & Tonic is a fantastic alternative. This non-alcoholic coffee variation utilizes cold brew concentrate, which works well with tonic as a lower-acidity option, resulting in a smoother, less bitter drink. It’s a simple espresso tonic that still captures the essence of the refreshing coffee drink experience without the need for specialized equipment, making it incredibly accessible for any home barista.

Ingredients

• 2 oz (60ml) cold brew coffee concentrate
• 5 oz (150ml) chilled tonic water
• Large ice cubes
• 1 lemon peel for garnish

Instructions

1. Fill a highball glass with ice cubes.
2. Pour the cold brew concentrate over the ice.
3. Top with chilled tonic water. Because both liquids are cold, they will mix together rather than layer.
4. Stir gently to combine.
5. Garnish by expressing the oils from a lemon peel over the drink and dropping it in.

Pro-Tip: Since this version doesn’t have the dramatic layers, focus on the garnish. Use a vegetable peeler to create a long, wide lemon peel. Twist it over the drink to release the oils, rub the rim of the glass with it, then curl it and drop it into the glass for a professional look and aroma. Understanding coffee bean acidity profiles reveals why cold brew’s lower acidity makes it a great pairing for the bitterness of tonic water.

FAQs About espresso tonic recipe

What tonic water is best for an espresso tonic?

A high-quality, less sweet tonic water like Fever-Tree Indian Tonic or Q Mixers is generally considered the best. These brands have a clean taste and sharp carbonation that complements espresso without being overly sugary. Look for tonics with natural quinine and avoid those with high-fructose corn syrup, as they can make the drink cloyingly sweet and mask the coffee’s flavor.

How do you make an espresso tonic less bitter?

To reduce bitterness, you can add a small amount of simple syrup (about 1/4 oz) or use a naturally sweeter tonic water, like an elderflower tonic. Choosing a less bitter, more fruit-forward espresso bean (like a natural-processed Ethiopian) can also significantly help. Finally, ensuring your espresso shot is not over-extracted is crucial, as over-extraction is a primary cause of excessive bitterness in coffee.

What does an espresso tonic taste like?

An espresso tonic has a unique bitter-sweet flavor profile with a refreshing, bubbly texture. You’ll first taste the bright, acidic, and roasted notes of the espresso, followed by the crisp, slightly bitter quinine flavor of the tonic water. The citrus garnish adds a fragrant, zesty aroma and finish, making the overall experience complex, invigorating, and surprisingly refreshing.

Can you make an espresso tonic with cold brew?

Yes, you can absolutely make a tonic drink with cold brew concentrate, and it’s a great alternative if you don’t have an espresso machine. As shown in Recipe #7, you simply mix cold brew concentrate with tonic water. The result is a smoother, less acidic, and less bitter drink compared to the espresso version, though it won’t have the distinct layered appearance.

How do you properly garnish an espresso tonic?

The best garnish is a citrus twist or wheel (lemon, lime, or orange). The key is to “express” the peel over the drink before adding it. Twist the peel over the glass to spray its aromatic oils onto the surface. This adds a powerful scent and flavor that is essential to the drink’s profile. Other great options include a sprig of rosemary or a dehydrated orange slice.

Why won’t my espresso tonic layer properly?

The most common reason for a lack of layers is insufficient temperature difference. The espresso must be hot and the tonic water very cold. If the espresso cools down or the tonic is lukewarm, the densities will be too similar, and they will mix. Pouring the espresso too quickly can also break the surface tension and cause mixing. Pour slowly over the back of a spoon for best results.

What kind of espresso works best for a tonic?

A modern, light-to-medium roast single-origin espresso with bright, fruity, or citrusy notes is ideal. Beans from Ethiopia, Kenya, or Colombia often work beautifully. These acidic and fruity notes complement the tonic and citrus garnish. Avoid very dark, oily, or “roasty” Italian-style blends, as their intense bitterness can clash with the quinine in the tonic water.

Can you add alcohol to an espresso tonic?

Yes, an espresso tonic makes a fantastic base for a low-ABV cocktail. Gin is a classic pairing, as it shares botanical notes with tonic water (creating an “Espresso Gin & Tonic”). Amaro, a bitter Italian liqueur, also works wonderfully. Start by adding about 1 oz of your chosen spirit to the glass before adding the tonic.

Is an espresso tonic caffeinated?

Yes, an espresso tonic is a highly caffeinated beverage. It contains a full shot (or double shot) of espresso. A typical double shot of espresso has between 100-150mg of caffeine, depending on the coffee beans and preparation. The tonic water itself is caffeine-free. For a low-caffeine version, you can use decaf espresso.

Why is my espresso tonic so foamy?

A large amount of foam is a natural chemical reaction between the hot, acidic espresso and the carbonated tonic water. The CO2 in the tonic is rapidly released when the hot liquid hits it, creating a foamy head. This is normal. To manage it, pour the espresso very slowly and use a tall glass to give the foam room to expand and settle.
