What is Dirty Matcha?

Dirty matcha is an tea made with matcha powder and coffee. While the thought of mixing green tea and coffee may sound weird at first, it's incredibly delicious. Both coffee and matcha have a strong flavour and some bitterness. Matcha is not as grassy as sencha, and more earthy than other green teas which makes it a great pair for a naturally bitter coffee.

Caffeine in Dirty Matcha

This drink contains more caffeine than a single espresso shot, as both ingredients, matcha and coffee, are naturally caffeinated. A shot of espresso will have around 60 mg of caffeine, same as matcha prepared with a teaspoon of matcha powder. 1/2 of matcha powder will be enough to make one serving, but feel free to use a whole teaspoon if you prefer a stronger flavour. To reduce the caffeine content, use decaf coffee.

Alternatively, you can even use flavoured coffee, such as hazelnut, chocolate, caramel or vanilla. The only thing to keep in mind is to use quality coffee that you enjoy drinking on its own too.
