Coffee and tonic water sounds like a mistake until you've had one. Then it sounds obvious.
Cafés have been serving espresso tonic for years — the bitterness of quinine and the bitterness of coffee don't compete, they stack, and the carbonation lifts aromatics you'd never notice in a flat drink. It's one of those combinations that reads badly on paper and works immediately in a glass.
This version adds orange and cinnamon, which turns it from a coffee drink into something closer to a mocktail.
A coffee spritz is iced coffee built with tonic water and citrus instead of milk. This one uses a spiced cinnamon coffee sachet, fresh orange juice and tonic, takes about five minutes, and needs no espresso machine.
What you need
- 1 sachet Bevzilla Spiced Cinnamon Coffee
- 2 oz hot water
- ½ oz fresh orange juice — about half a small orange
- 4–5 oz tonic water, well chilled
- Ice, as much as the glass takes
- A tiny pinch of sea salt
- Orange peel, and a rosemary sprig if you have one
Fresh orange juice matters here. Bottled juice is sweeter and duller, and in a drink this simple there's nowhere for it to hide.
How to make it
1. Dissolve the coffee. One sachet into 2 oz of hot water, stirred until smooth. Give it a minute to cool — pouring hot coffee straight onto ice melts it fast and waters the whole thing down.
2. Build the base. Fill a tall glass with ice. Add the orange juice and the pinch of salt, and give it a quick stir.
3. Add tonic slowly. Pour down the side of the glass or against a spoon. Tonic loses its carbonation the moment you dump it in, and flat tonic makes a flat drink.
4. Float the coffee. Pour it over the top, slowly. It'll sit in a dark layer above the tonic for a few seconds before it bleeds down, which is the shot worth photographing.
5. Finish. One gentle stir — not more. Twist the orange peel over the glass so the oils land on the surface, then drop it in with the rosemary.
What it tastes like
The order matters, and you get it in sequence: cinnamon first, then coffee, then a bright hit of orange, then the dry bitter fizz of the tonic, and a faint salty edge at the very end.
It's aromatic rather than sweet, and considerably more interesting than another glass of coffee and milk.
Why orange, cinnamon and coffee work together
None of this is a random pairing. Coffee carries fruit and citrus notes on its own — tasting notes for washed Ethiopian and Kenyan beans reference citrus constantly — so adding orange amplifies something already present rather than importing a foreign flavour.
Cinnamon bridges the two. It's warm and slightly sweet without any sugar, and it sits comfortably alongside both the roast character of coffee and the brightness of orange. Orange and cinnamon have been paired in cooking and baking for centuries for the same reason.
The tonic does the structural work. Quinine's bitterness runs parallel to coffee's rather than fighting it, and the carbonation carries the aromatics up out of the glass. It's why an espresso tonic smells stronger than an iced latte made from the same shot.
And the salt — a genuinely tiny pinch — suppresses bitterness slightly and makes the orange read brighter. It's the same reason salt goes into a grapefruit margarita.
Three things that will ruin it
Adding milk. Orange juice will curdle dairy. There is no version of this drink with a splash of milk in it, and no amount of stirring will fix it once it's happened.
Warm tonic. Chill it properly. Room-temperature tonic hitting ice goes flat almost immediately and you lose the entire point of the drink.
Over-stirring. One gentle pass. Every extra stir costs you carbonation, and the layered look disappears within seconds anyway.
Variations worth trying
Grapefruit instead of orange. Sharper and more bitter — closer to an adult aperitif than a refreshment.
Rosemary muddled rather than garnished. Press the sprig against the ice before you build. Herbal and slightly savoury, and it changes the drink more than you'd expect.
Soda water instead of tonic. Less bitter, less sweet, and it lets the cinnamon sit further forward. Also removes the tonic's sugar entirely.
A large clear cube instead of crushed ice. Melts slower, so the drink holds its strength to the bottom of the glass.
What's actually in the glass
Worth being straight about this, since we spend a lot of time telling people to read labels.
The coffee sachet contributes 5 calories and [CAFFEINE — CONFIRM] mg of caffeine. The half-ounce of orange juice adds roughly 7. The tonic water is where the calories are: standard tonic carries sugar, so 4–5 oz adds somewhere around 40 to 50 calories. Total, you're looking at a drink in the region of 50 to 60 calories.
That's still a fraction of a café flavoured iced coffee. But it isn't zero, and tonic water gets treated as though it were far more often than it should be. Zero-sugar tonic brings the total back down near 15 calories if that matters to you.
Frequently asked questions
What is a coffee spritz?
A coffee spritz is an iced coffee drink built with sparkling water or tonic and citrus rather than milk. It's a variation on the espresso tonic, a café format that pairs coffee with tonic water over ice, and it's typically served tall with a citrus garnish.
Does coffee actually taste good with tonic water?
Yes, and it's a long-established café drink rather than a novelty. Quinine's bitterness complements coffee's rather than clashing with it, and the carbonation carries the coffee's aromatics, making the drink smell and taste more expressive than a still iced coffee.
Can I make a coffee spritz without an espresso machine?
Yes. Dissolving an instant coffee sachet in 2 oz of hot water gives you a concentrated base that works the same way an espresso shot does in this drink. No machine, no grinder, no filter.
Can I add milk to a coffee spritz?
No. The citrus will curdle dairy. If you want a creamy iced coffee, leave out the orange juice and the tonic and make a latte instead — they're different drinks.
How many calories are in a coffee spritz?
Made as written with standard tonic water, roughly 50 to 60 calories, most of which comes from sugar in the tonic. Using zero-sugar tonic or plain soda water brings it down to around 15.
Can I make it ahead?
Only partly. Dissolve the coffee and refrigerate it, but build the drink itself immediately before serving — carbonation doesn't survive sitting, and a pre-mixed spritz is a flat spritz.
