An iced matcha latte is whisked matcha over cold milk and ice. A clear guide gives you the method plus a candid word on the caffeine and sugar the pretty green colour disguises.
What you need
Per serving: about half to one teaspoon of matcha (culinary grade is fine for a latte), a small amount of hot, not boiling, water (around 70 to 80C) to mix it, cold milk or a milk alternative, ice, and sweetener only if you want it. A bamboo or small electric whisk helps a lot.
How to make it, step by step
Sift the matcha into a cup or jar (sifting removes the clumps that cause grittiness). Add a little hot but not boiling water and whisk briskly in a W or M motion until smooth and frothy with no lumps; boiling water scalds matcha bitter, so keep it below the boil. Pour over a glass of ice and cold milk, stir, and sweeten only to taste.
How to make it genuinely good
A good iced matcha latte is about no lumps and decent matcha: sift and whisk properly (or shake hard in a sealed jar if you have no whisk), use water below boiling, and use a matcha that is at least a sound culinary grade. A dull, cheap, badly stored matcha tastes flat and bitter no matter how you make it. Fresh, vivid green powder, well sifted, is most of the quality.
A word of caution
Matcha is whole leaf green tea, so per serving it is more caffeine concentrated than a cup of steeped green; the soft, milky, iced presentation disguises a real dose. It is a poor late evening choice if you are caffeine sensitive. And a cafe iced matcha latte is frequently sweetened, sometimes heavily; made at home it is essentially unsweetened unless you add sugar, which is the clear advantage; the vivid colour and the lift are real, and the sweetness is entirely your decision.
Iced matcha latte, at a glance
| Element | Short rule |
|---|---|
| What it is | Whisked matcha over cold milk and ice, lightly sweetened |
| Whisk first | Whisk matcha smooth in a little cool water before it meets milk |
| Water temp | Cool, not boiling; boiling scalds matcha bitter |
| Strength | Use enough matcha; ice and milk dilute it |
| Sweeten | Lightly and to taste, not the cafe default |
