The iced matcha latte is how most people fall in love with matcha — and also where most homemade versions go wrong. Clumps of dry powder, a bitter edge, or a drink that separates into green water and white milk before you have taken three sips. All three problems have the same few causes, and all of them are fixable without any special equipment.
What you need
- 2 grams of matcha (about one teaspoon, level)
- 30ml hot water — hot tap or kettle water rested a few minutes; roughly 80°C, never boiling
- 200ml cold milk — dairy, oat and soy all work; oat foams best over ice
- Ice
- A whisk — a bamboo chasen if you have one, a small kitchen whisk or a battery frother if you don't
The method (two minutes)
- Sift the matcha into a bowl or cup. This is the step everyone skips and the reason most home lattes clump. Matcha is so finely milled that it compacts in the tin; thirty seconds through a small sieve undoes that completely.
- Add the hot water and whisk. Whisk briskly in an 'M' motion — not circles — for about fifteen seconds, until the surface is smooth with a fine foam and no dry specks remain. You have just made a concentrated shot of matcha.
- Fill your glass with ice, pour the milk over it.
- Pour the matcha shot over the top. It will sink and marble through the milk — the two-layer look everyone photographs. Stir before drinking.
That is the whole technique. The order matters: matcha dissolves properly only in a small amount of warm water first. Powder stirred straight into cold milk will never fully combine — that is physics, not your fault. If you want to go deeper on whisking technique and the traditional preparation, we walk through it step by step on our ritual page.
Three mistakes worth avoiding
- Boiling water. Water straight off the boil scorches the powder and drags out bitterness. Let the kettle sit for three or four minutes first.
- Too much powder. More matcha does not mean more flavour — past a point it just means chalk and bitterness. Two grams is right for one glass.
- Culinary powder for straight lattes. Cheap, dull-green matcha needs sugar to be drinkable. A naturally sweet, well-milled powder needs nothing.
Which matcha to use
For lattes specifically, you want a powder that is mild, creamy and naturally sweet — one blended for milk rather than fighting it. That is exactly what our Surrender was made for: 100% Yabukita leaves, ceramic-milled for a fine, even texture, with a soft sweetness and no sharp edges. If you prefer your latte with more presence — a deeper, more savoury green — try Breathe, our balanced everyday matcha from Yame.
A note on sweetener
Try it unsweetened first. Good matcha over cold milk has its own gentle sweetness, and many people who "need" sugar in their matcha latte have only ever had bitter powder. If you do want it sweeter, a small spoon of honey or maple syrup whisked into the hot shot (step 2) dissolves far better than anything added at the end.
Once the sifting habit sticks, this takes less time than standing in a café queue — and the ritual of it is half the pleasure.
