A large glass of milk with a little matcha can look green and still taste mostly of milk. This starting recipe uses a measured tea base, then leaves room to adjust the balance without changing everything at once.
It is intended for ordinary unsweetened matcha powder. A sweetened café premix needs its own recipe because part of its weight is sugar or other ingredients.
Iced matcha latte
1 glass · About 5 minutes
Original starting formula; not kitchen-tested by Alpha Natural. Adjust to your matcha and milk.
Ingredients
| Ingredient | Amount |
|---|---|
| Unsweetened matcha powder | 2 g |
| Water, approximately 80°C | 40 g |
| Chilled milk or a suitable plant drink | 160 g |
| Ice | 80 g |
| Granulated sugar, optional | 0–8 g |
Method
- Sift the matcha into a small bowl or wide cup.
- Add about 10 g of the warm water and work it into a smooth paste. Whisk in the remaining water. If using sugar, dissolve it in the warm tea base.
- Put the ice into a serving glass and add the chilled milk.
- Pour in the matcha base, stir and taste. Serve immediately.
Milk if using dairy. Check plant-drink labels for soy, nuts, oats and other relevant allergens.
Why prepare a separate tea base?
Sifting and whisking the powder with warm water before adding milk is an established preparation method. Ippodo uses 80°C water for its latte recipe. The version below uses a smaller water portion and cold milk for an iced drink; it is an original trial formula, not a reproduction of Ippodo’s recipe.

Adjust one thing at a time
Taste before adding all the optional sweetener. If the tea seems weak, make a second glass with 2.5 g of matcha while keeping the other quantities fixed. If it is too strong, try 1.5 g. Writing down the change makes the next glass easier to reproduce.
Keep the milk brand consistent during this comparison. A sweetened oat drink and an unsweetened dairy milk bring different flavours and sugar levels, so a change of milk can look like a change in matcha quality.
Ice matters too. Serve promptly, then taste the same drink again after ten minutes. If it becomes too diluted for your intended serving style, evaluate the amount of ice or the starting liquid volume rather than immediately adding more powder.
Troubleshooting the glass
Dry specks usually call for a better first mixing step. Break up clumps in the sieve, then add only a little water to form a smooth paste before whisking in the rest. Pouring dry powder directly onto a finished iced latte makes even wetting harder.
A settled layer is different from a dry lump. Stir the drink and reassess it before deciding that the powder is unsuitable. A hand-prepared latte is not a shelf-stable ready-to-drink product.
Taking this recipe into a café
For ten glasses, multiply the weighed ingredients by ten, but add ice to each glass at service. Start with a small service trial: preparation speed and consistency can matter as much as the result from one carefully made cup.
Use clean utensils and keep milk chilled until needed. This article does not establish storage life for a prepared batch. For a bottled product, processing, microbiology and shelf life need separate validation.
