What Exactly Is a Dirty Matcha?
A dirty matcha is a simple but creative hybrid drink: a matcha latte with a shot of espresso poured over it. The name comes from the visual effect of the dark espresso “dirtying” the vibrant green of the matcha and milk. It follows the same naming convention
as a dirty chai, which is a chai latte with an added espresso shot. The result is a striking, often layered beverage that combines two of the world's most popular caffeinated drinks into one cup. Whether served hot or iced, its unique appearance, with swirls of brown cutting through green, is a significant part of its appeal, making it a social media favourite.
A Tale of Two Flavours
Combining the bold, roasted flavour of coffee with the earthy, umami notes of matcha might sound unusual, but the result is surprisingly complex and balanced. The taste experience starts with the bitterness of the espresso, followed by the creamy sweetness of the milk, and finishes with the distinct, slightly grassy flavour of matcha. The final profile depends heavily on the quality of the ingredients and the ratios used. Using a ceremonial grade matcha can provide a smoother, less bitter green tea flavour to counterbalance the robust espresso. The milk, whether dairy or a plant-based alternative like oat milk, adds a creamy texture that marries the two distinct tastes.
From Niche Trend to Café Staple
The dirty matcha has ridden a wave of popularity driven by café culture's love for experimentation and our collective fascination with photogenic food. Its rise in India is part of a broader matcha boom, with Google searches for the green powder surging in recent years. Indian consumers are not just adopting matcha but adapting it, with variations like mango matcha and coconut matcha also gaining traction. The dirty matcha, in particular, resonates as it bridges two strong beverage cultures: India’s love for tea and a growing appreciation for speciality coffee. It has become a fixture in urban cafés in cities like Delhi and Goa, appealing to adventurous customers.
The Caffeine Question
Combining matcha and espresso creates a potent caffeine kick. However, the experience is often described as different from a straight coffee buzz. This is thanks to L-theanine, an amino acid present in matcha. L-theanine is known for promoting a state of “calm alertness,” which can help smooth out the jitters sometimes associated with the sharp caffeine spike from espresso. Many drinkers report a more sustained, focused energy without the typical coffee crash. While both coffee and matcha have their own health benefits, such as being rich in different types of antioxidants, the dirty matcha offers a unique combination. Matcha is rich in catechins like EGCG, while coffee is high in chlorogenic acids.
How to Make Dirty Matcha at Home
Creating your own dirty matcha is straightforward. You will need matcha powder, hot water, milk of your choice, and a shot of espresso or strongly brewed coffee. First, prepare the matcha by sifting about one teaspoon of powder into a bowl. Add a few tablespoons of hot (not boiling) water and whisk vigorously until smooth and frothy. If you like it sweet, this is the best time to whisk in a sweetener like maple syrup or honey. Next, fill a glass with ice for a cold version, or use a mug for a hot one. Pour in your milk, followed by the prepared matcha. Finally, slowly pour your freshly brewed shot of espresso over the top to create the signature layered “dirty” effect. You can leave the layers for visual appeal or stir to combine the flavours before drinking.
