Matcha Tonic Recipe

A matcha tonic is exactly what it sounds like: freshly whisked matcha poured over ice into a glass of cold tonic water. The matcha layers on top, the tonic floats beneath, and the visual alone is enough reason to make it.

The flavor is more interesting than either ingredient on its own. Matcha is grassy, slightly sweet, and lightly bitter. Tonic is cold, carbonated, and bitter in a different register. They balance each other in the same way espresso and tonic do — which is why this drink took off after the espresso tonic trend did.

The key variable is the tonic.

Why the Tonic Water Matters More Than You Think

Most matcha tonic recipes call for commercial tonic water. The problem is that standard tonic water contains 20 to 24 grams of sugar per serving. That sugar does not play well with matcha, which has its own delicate sweetness from the L-theanine in the leaves. Commercial tonic flattens the matcha flavor into a generic sweet-bitter drink.

A tonic syrup with lower sugar — like Jo's Original Tonic Concentrate, which has 6 grams of sugar per serving — lets the matcha stay present. You get the tonic's quinine bitterness as a counterpoint to the matcha, without the sugar overwhelming what makes matcha interesting in the first place.

The carbonation from fresh sparkling water also holds better than pre-bottled tonic that has been open for any amount of time. In a drink where the visual layering is part of the experience, you want those bubbles to be active when the matcha hits them.

Serves 1

1 tsp ceremonial grade matcha powder (2g)
2 oz hot water (160-175°F, not boiling)
1 oz Jo's Original Tonic Concentrate
4 to 5 oz sparkling water, cold
Large ice
Lemon slice or mint sprig to garnish

Make the matcha concentrate. Sift the matcha powder into a small bowl. Add 2 oz of hot water and whisk briskly with a bamboo whisk or a small milk frother until smooth and frothy — no clumps. Let it cool for 2 to 3 minutes.

Build the tonic base. Fill a tall glass with ice. Add the Jo's tonic concentrate and top with cold sparkling water. Stir gently once to combine.

Layer the matcha. Pour the matcha concentrate slowly over the back of a spoon or directly down the inside of the glass so it floats on top of the tonic. The green layer will sit briefly before mixing — that is the visual moment the drink is known for.

Garnish and serve. Add a lemon slice or a small sprig of mint. Serve immediately.

To skip the layering effect: If you prefer a blended drink over the visual, just pour the matcha in and stir. The flavor is the same.

The Ratio

The tonic syrup-to-sparkling water ratio controls how strong the tonic character is. At 1:5 (1 oz syrup, 5 oz seltzer), the tonic is clean and relatively light — the matcha comes forward. At 1:4, the tonic bitterness is more prominent. Adjust to what you want in the specific drink.

Do not sweeten unless you need to. Ceremonial grade matcha has natural sweetness. The tonic concentrate has some. Added sweetener often pushes the drink into soda territory, which is not the point.

If you find the matcha too bitter on its own, the problem is usually the water temperature. Matcha brewed above 175°F turns harsh. Keep the water between 160°F and 170°F for a cleaner, sweeter result.

Turn It Into a Cocktail

A matcha tonic becomes a matcha gin and tonic by adding 1.5 to 2 oz of gin before you layer the matcha.

The best gins for this are ones with a strong botanical character — particularly anything with juniper, cucumber, or floral notes. The matcha and gin share earthy, herbal ground that makes them work together. Hendrick's (cucumber and rose) and Tanqueray Rangpur (lime) are two that translate well.

Matcha Gin Tonic

1.5 oz botanical gin
1 oz Jo's Original Tonic Concentrate
4 oz sparkling water
1 tsp ceremonial matcha whisked with 2 oz hot water, cooled
Large ice
Lemon peel garnish

Build the tonic in the glass: gin, tonic syrup, sparkling water over ice. Layer the cooled matcha on top. Garnish with a lemon peel.

The gin-forward version is closer to the espresso tonic category — a botanical tonic drink that happens to use green tea as the bitter element instead of coffee.

Matcha Tonic vs. Matcha Latte

These are solving different problems.

A matcha latte is warm, creamy, and grounding. It is a morning ritual or an afternoon pause. The milk softens the matcha's bitterness and rounds the whole drink into something comfortable.

A matcha tonic is cold, bright, and caffeinated in a different register. The carbonation makes it active. The tonic bitterness sharpens the matcha rather than softening it. It wakes you up the way iced coffee does, but with a cleaner energy profile — matcha contains L-theanine alongside its caffeine, which produces a focused alertness rather than a jittery spike.

If you want something hot and comforting, make the latte. If you want something cold that keeps you functional, make the tonic.

A Note on Matcha Quality

The visual effect — the bright green layer — only works with high-quality matcha. Culinary grade matcha is designed for baked goods and blended drinks where color and flavor will be modified by other ingredients. In a matcha tonic, where the matcha sits unblended at the top of the glass, culinary grade produces a dull, yellowish-green that tastes noticeably more bitter and less complex.

Ceremonial grade matcha is the right choice here. It is more expensive per gram, but you are using only a teaspoon at a time — one tin will make many drinks. Brands like Ippodo, Encha, and Chalait are widely available online.

Frequently Asked Questions

Does matcha tonic have caffeine? Yes. Matcha contains about 30 to 40 mg of caffeine per gram of powder. A standard recipe using 2 grams of matcha has roughly 60 to 80 mg of caffeine — similar to a shot of espresso, but with L-theanine, which modulates the effect for a calmer alertness.

Can I make matcha tonic without whisking? You can use a milk frother or a small blender to mix the matcha concentrate. A fork will not produce a smooth result. If you do not have a whisk or frother, dissolve the matcha in a small amount of very hot water first and stir vigorously before adding more.

Does matcha tonic have alcohol? The base recipe has no alcohol. Add gin, vodka, or another spirit if you want to make a cocktail version.

Is matcha tonic good for you? Matcha is high in antioxidants and contains L-theanine alongside its caffeine. Tonic water contributes quinine. Jo's tonic syrup adds 6 grams of sugar per serving. The drink is not a health supplement, but compared to a soda or most flavored drinks, the ingredient list is clean.
