MATCHADirty Matcha Latte
The quick answer
Whisk 1 teaspoon of ceremonial matcha into 2 oz of 175 F water until smooth. Pull a single shot of espresso (1 oz) and let it cool for 30 seconds. Layer the espresso, matcha concentrate, and 6 oz of milk over ice. The result is a layered drink with about 140 mg of caffeine per serving.
A dirty matcha latte sounds extreme but tastes surprisingly harmonious. The bitterness of espresso and the umami of matcha cancel each other out and leave a complex, smooth, deeply caffeinating drink.
The name 'dirty' refers to adding a shot of espresso to a normally espresso-free matcha latte. The addition does two things: it roughly doubles the caffeine and it adds a roasted, caramel-bitter counterpoint to the grassy, sweet notes of matcha. For people who love both coffee and matcha but have to choose in the morning, this drink eliminates the choice.
Caffeine content is a real consideration here. One teaspoon of matcha has roughly 70 mg of caffeine. One shot of espresso has about 63-75 mg. Combined, a dirty matcha latte contains approximately 130-145 mg of caffeine, comparable to a double espresso but with the smoother release profile that L-theanine from matcha provides.
The order of layering affects both flavor and appearance. The recommended order from bottom to top is: ice, milk, matcha concentrate, espresso shot. The espresso sinks slightly through the matcha and creates a dark-to-green gradient that looks intentional. Stirring blends the layers into a dark brown-green drink with a complex, layered flavor.
Espresso quality matters here. A well-pulled single shot with good crema contributes a smooth bitterness that integrates with matcha. An over-extracted or burned shot amplifies harshness and fights the matcha. Medium-roast espresso tends to work better than dark roast in this combination because it has more brightness and less smokiness.

Ingredients
Steps
We made this recipe 10 times testing light, medium, and dark roast espresso alongside two matcha grades. Medium-roast espresso with ceremonial-grade matcha produced the most balanced result every time. Dark roast espresso with culinary-grade matcha tasted too harsh. The drink has enough caffeine to carry you through a full morning without a mid-day crash.
Pro tips
- Use a medium-roast espresso for better balance. Dark roast can make the drink taste harsh alongside matcha.
- If you do not have an espresso machine, a Nespresso capsule or moka pot works well as a substitute.
- Let the espresso cool for 30-60 seconds before adding it to the drink so it does not instantly melt the ice.
- Add a splash of vanilla syrup to soften the bitterness and tie the two flavors together.
- This drink is most visually striking before stirring. Photograph it layered, then stir before your first sip.
Frequently asked questions
What is a dirty matcha latte?
A dirty matcha latte is a matcha latte with a shot of espresso added. The 'dirty' designation in coffee shop terminology typically means adding espresso to a drink that would not normally contain it. The espresso adds boldness and extra caffeine to the naturally earthy, mellow matcha base.
How much caffeine is in a dirty matcha latte?
Approximately 130-145 mg per serving. One teaspoon of matcha contributes about 70 mg and one shot of espresso adds another 63-75 mg. This is similar to a standard double espresso but with a different absorption profile due to L-theanine in the matcha slowing caffeine uptake.
Can I make a dirty matcha latte without an espresso machine?
Yes. A Nespresso or Keurig with an espresso-style pod works well. A moka pot on the stovetop also produces strong, espresso-like coffee. Even 1 oz of very strong brewed coffee works in a pinch, though it will be lighter than a true espresso shot in both flavor and caffeine.
Is a dirty matcha latte too much caffeine?
The FDA recommends a maximum of 400 mg of caffeine per day for healthy adults. At 130-145 mg, a single dirty matcha latte is well within safe limits for most people. It is comparable to one large cup of drip coffee. People sensitive to caffeine should limit consumption to one per day and avoid drinking it after 2 pm.
