The short answer
Sift 2 g of matcha into a small jar or bowl, add 40 ml of water (75°C to whisk, or cold to shake), and mix until smooth. Fill a tall glass with ice and 180 ml of cold milk, then pour the matcha over the top. It takes three minutes and carries about 64 mg of caffeine.

Recipe card
Iced matcha latte
Ingredients
- 2 g matcha (1 level teaspoon is about 2 g)
- 40 ml water, 75°C or cold
- 180 ml cold milk
- 1 cup ice
- Honey, maple or simple syrup to taste (optional)
Method
Tap a step to tick it off.
- Sift the matcha into a bowl or a small shaker jar.
- Bowl: add 40 ml of 75°C water and whisk in a quick zigzag for about 30 seconds until smooth and foamy. Jar: add 40 ml of cold water, seal and shake hard for 20 seconds.
- Fill a tall glass with ice and pour in the cold milk. Sweeten the milk now if you like; syrup mixes better than sugar in cold drinks.
- Pour the matcha slowly over the top for the layered look, then stir before drinking.
Shake or whisk?
Cold water dissolves matcha well if you shake hard, but slightly warm water releases more of the sweet aroma. Best of both? Whisk with 40 ml of warm water. The ice and cold milk chill it instantly.
Which matcha for iced lattes?
Milk and ice mute delicate flavours, so a bold matcha works best. Our Superior Culinary is made for exactly this and keeps its colour in milk. Want a smoother, sweeter latte? Use Ceremonial Grade from our family farm.

Four summer variations
Matcha cold foam
Shake 1 g matcha with 60 ml cold cream and a teaspoon of syrup until thick. Spoon over iced milk or cold brew.
Strawberry matcha
Mash strawberries in the bottom of the glass before the milk. Full recipe in our strawberry matcha guide.
Matcha lemonade
Shake 2 g matcha with 200 ml cold water, the juice of half a lemon and a spoon of honey. No milk, very refreshing.
Coconut matcha
Chilled coconut water or coconut milk instead of dairy for a lighter, tropical glass.
Batch it for a heatwave week
Whisk 10 g of matcha with 200 ml of water, bottle it and keep it in the fridge. Each morning, shake the bottle and pour 40 ml over ice and milk.
Use it within a day for the best colour. Matcha mixed with water slowly loses its bright green and fresh flavour.
How much caffeine is in an iced matcha latte?
Matcha powder has about 3.2 g of caffeine per 100 g, or 32 mg a gram (Japan's food composition tables). A 2 g latte is about 64 mg, a little under a 250 ml cup of brewed coffee. A double with 4 g is about 128 mg.
