Dirty matcha combines matcha tea, milk and coffee in one glass. This iced version uses instant coffee, so you can make it without an espresso machine. Prepare the coffee and matcha separately, add cold milk and ice, then stir before drinking for an even balance of both flavors.

The recipe starts with one teaspoon each of matcha and instant coffee. That makes it easier to adjust the two flavors than beginning with a large dose of either. Both ingredients generally contain caffeine; this drink has no measured caffeine value and is not presented as a low-caffeine alternative.

Recipe development note: This formulation has not been kitchen-tested. Preparation times are estimates; follow the texture checks and product instructions.

Selecting matcha, instant coffee and milk

Choose plain matcha powder you enjoy in a milk drink. Labels such as ceremonial or latte grade do not replace tasting the product. Follow its storage instructions and keep the package closed between uses.

Instant coffee should dissolve completely before it reaches the ice. A premixed coffee sachet will change the sugar and milk amounts, so use plain granules. Decaf instant coffee reduces the coffee component's caffeine, but matcha still contributes caffeine.

Cold milk softens the intensity of the tea and coffee. Dairy milk, oat milk and soy milk give different flavors and textures. Use the variety you prefer, and shake a milk-alternative carton before measuring.

Step 1: Dissolve and cool the coffee

Put the instant coffee in a small heatproof cup and stir in the hot water until no dry granules remain. Let it cool for about 5 minutes, or stand the cup in a bowl of cold water. It should no longer be steaming when added to the glass.

Step 2: Sift and whisk the matcha

Sift the matcha into a small bowl. Add the warm water and optional sugar. Whisk in quick back-and-forth strokes until the sugar dissolves and no dry matcha pockets remain. A handheld frother can also work in a deep cup, with care to avoid splashing warm liquid.

Step 3: Add matcha, ice and milk

Pour the whisked matcha into a tall 16-ounce glass. Add about 3/4 cup of ice, then pour in the cold milk. Pour slowly over the ice if you want some temporary separation between the green tea and milk.

Step 4: Pour in the coffee and stir

Add the cooled coffee slowly over the milk. Brown and green swirls may show briefly; exact layers are not required. Stir thoroughly before drinking so the first sip is not just coffee. Taste, and add a little more milk if both flavors are too strong.

Correcting clumps and an overly bitter drink

Dry matcha clumps need attention before the milk goes in. Sifting breaks them apart, and whisking suspends the fine particles in water. Matcha does not dissolve like sugar, so a small amount of settling can happen. Stir again while drinking rather than treating settling as a failed recipe.

If the drink is bitter, work out whether the coffee or matcha is responsible by tasting a small cooled amount of each component. For the next glass, reduce that ingredient to 1/2 teaspoon. Adding a large amount of sugar can hide the problem without improving the balance. Check the matcha package's water-temperature instructions as well.

Adjusting the coffee-to-matcha balance

To make the tea more prominent, reduce instant coffee to 1/2 teaspoon while keeping its water amount the same. To make the coffee more prominent, reduce matcha to 1/2 teaspoon. Use decaf instant coffee if preferred, while remembering that the tea still contains caffeine. A liquid sweetener can be stirred into the finished drink in small amounts. This version uses plain milk rather than a cream topping, keeping the method short and the flavors easier to adjust.

Serving the drink fresh and keeping components cold

Whisk matcha and assemble the latte close to serving time. If you dissolve the coffee ahead, cover it, refrigerate promptly and use it the same day. Keep the milk cold and add ice when serving. Refrigerate any unfinished milk-based drink promptly and use it the same day for best texture. Do not leave perishable drinks at room temperature for more than two hours, or one hour above 90°F/32°C.

Questions about this recipe

Why is it called dirty matcha?

The name refers to adding coffee to a matcha latte. It does not mean the drink contains anything unclean. Here the coffee portion comes from instant granules rather than espresso.

Can I make it without a bamboo whisk?

Use a handheld frother in a deep cup after sifting the powder. A small ordinary whisk is another option. Whisk the matcha with its measured water before adding milk.

Will it stay in three neat layers?

Layers depend on temperature, milk, pouring speed and the glass. They are temporary and mainly visual. Stir before sipping so the coffee and matcha do not arrive as separate strong mouthfuls.
