What Exactly Is a Dirty Matcha?
At its core, a dirty matcha is a matcha latte with a shot of espresso added. The name follows a familiar café pattern, much like a 'dirty chai', where adding espresso to a tea-based drink 'dirties' it. Visually, this creates a beautiful, often Instagram-worthy,
layered effect with dark, rich espresso streaking down through the vibrant green matcha and creamy milk. Some baristas have even nicknamed it a 'camo latte' for its swirling brown and green patterns. It’s a hybrid beverage that has surged in popularity, thanks in part to social media platforms like TikTok, where its unique appearance and novel flavour combination have made it a viral sensation.
The Tale of Two Flavours
So, what does this intriguing combination actually taste like? The experience is a complex interplay of its core components. On one side, you have the matcha, which brings a distinct earthy, grassy, and slightly sweet umami flavour. On the other, the espresso shot delivers its characteristic bold, roasted bitterness and rich aroma. When combined with the creaminess of milk, the result is a balanced drink that harmonises these seemingly opposite profiles. The coffee's intensity cuts through the vegetal notes of the matcha, while the matcha's smoothness can temper the espresso's acidic edge, creating a profile that is at once robust, earthy, and creamy.
A Different Kind of Buzz
Beyond its taste, the dirty matcha offers a unique energy boost by combining two different sources of caffeine. An 8-ounce cup of brewed coffee typically contains around 96 mg of caffeine, while a single shot of espresso has about 63 mg. A standard serving of matcha, using about two grams of powder, can contain anywhere from 40 to 90 mg of caffeine. While combining them certainly packs a punch, the experience is often described differently from a straight coffee buzz. Matcha contains L-theanine, an amino acid known for promoting a state of 'calm alertness'. Many drinkers report that the L-theanine helps to smooth out the sharp jolt from the espresso, resulting in a more sustained, focused energy without the jitteriness that coffee can sometimes cause.
The Rise of a Hybrid Hero
The idea of combining matcha and espresso isn't entirely new, with Starbucks launching a 'Matcha & Espresso Fusion' in some Asian markets around 2016. However, its recent explosion into the mainstream is a product of modern café culture, which thrives on experimentation and creating visually appealing, shareable drinks. As matcha lattes became a staple offering in coffee shops worldwide, it was only a matter of time before the 'dirty' concept was applied. The drink appeals to both coffee lovers looking to try something new and matcha enthusiasts seeking an extra kick, bridging the gap between two of the world's most popular beverages.
Your At-Home Barista Guide
The good news is that you don't need to be a professional barista to enjoy a dirty matcha at home. The process is simple.First, prepare your matcha. Sift one to two teaspoons of matcha powder into a small bowl to remove clumps. Add a few tablespoons of hot (not boiling) water and whisk vigorously until the mixture is smooth and frothy. A bamboo whisk is traditional, but a small electric milk frother works wonderfully. If you prefer a sweeter drink, this is the time to whisk in a sweetener like maple syrup or honey.Next, assemble the drink. For an iced dirty matcha, fill a tall glass with ice and pour in your milk of choice (whole milk, oat, and almond are all great options). Pour your prepared matcha mixture over the milk. Finally, brew a shot of espresso and slowly pour it over the top to create those signature layers. For a hot version, simply use steamed milk and stir all the components together in a mug.
