Matcha soda is a bright answer for a hot day when you want something lighter than a latte but more playful than a plain clear cup. The key is simple: make a smooth matcha base first, then add cold sparkling water slowly so the drink stays lively and still tastes clearly like matcha.
The short answer
For a 360ml matcha soda, sift 5g matcha and whisk it with 60ml warm water at about 55 C. Fill a 360ml cup with ice, add about 170ml chilled sparkling water, then slowly pour in the smooth matcha base. Stir once or twice, gently. Add a small amount of brown sugar only if you prefer a sweeter finish.
Choose a matcha you enjoy in a clear cup, because milk will not be there to soften the flavour. Browse the Forest Cloud matcha collection by cup style, and keep a whisk, frother or shaker from Matcha Tools & Essentials nearby for the base.
Why the order matters
Matcha is finely milled tea leaf that stays suspended in a drink. It does not dissolve like instant drink powder. If dry matcha goes straight into cold sparkling water, it can clump, float or settle before the cup comes together. Whisking it first with warm water gives the powder a smooth start.
It also protects the fizz. Sparkling water brings a crisp finish, but it makes a rough or overly hot matcha base more obvious. Make the base smooth before the bubbles arrive, then pour slowly and stir as little as possible.
| If this happens | Try this first |
|---|---|
| The soda tastes sharp | Use water around 55 C for the matcha base rather than boiling water. |
| There are clumps | Sift the matcha and whisk it with the 60ml warm water before building the drink. |
| The soda goes flat | Keep the sparkling water chilled, add it over ice and stir only once or twice. |
| The matcha disappears | Return to the 5g base before adding more syrup or fruit. |
The 360ml matcha soda method
- Sift 5g matcha into a bowl, small jug or shaker.
- Add 60ml warm water at about 55 C and whisk, froth or shake until smooth.
- Fill a 360ml cup with ice.
- Pour in about 170ml chilled sparkling water.
- Slowly pour the smooth matcha base over the drink.
- Stir gently once or twice and drink while the soda is lively.
If you prefer a sweeter drink, dissolve a small amount of brown sugar in the warm matcha base before it reaches the sparkling water. Do not add dry sugar after the sparkling water; it will settle rather than help the drink come together.
Keep the first cup simple
Plain matcha soda is the best first version because it tells you whether the matcha, water and fizz are balanced. Once that works, make small changes instead of changing everything at once.
- Keep it plain: matcha, ice and sparkling water for the clearest matcha expression.
- Add citrus carefully: a strip of lemon peel or a small squeeze can brighten the cup, but too much can cover the matcha.
- Sweeten deliberately: dissolve a little brown sugar in the warm base, then taste before adding more.
- Use fruit as an occasional variation: keep the matcha base steady so the drink still tastes like matcha.

Tools that make it easier
You do not need a large setup. The main job is making the 60ml base smooth before it reaches the sparkling water. A bamboo whisk gives good feedback on texture. A handheld frother is quick for one serving. A shaker can work well for cold drinks, but shake only the matcha and warm water—never the sparkling water.

Adjust one thing at a time
If the drink is weak, confirm the 5g matcha and smooth 60ml base before adding syrup. If it tastes sharper than expected, check the water temperature. If it feels grainy, sift the powder and whisk longer. If it loses its fizz, use colder sparkling water, more ice and less stirring.

Choose by the cup you want
Matcha soda sits closer to a clear cup than a latte, so choose it when you want a more direct, cold matcha experience. Use the same method if you are comparing different matcha styles, then decide which one stays balanced with cold water and fizz.

FAQ
Can I put matcha directly into sparkling water?
It is better to whisk matcha with 60ml warm water at about 55 C first. That smooth base is less likely to clump or sit on top of the sparkling water.
How much matcha should I use for a 360ml matcha soda?
Start with 5g matcha whisked with 60ml warm water at about 55 C, then add ice and about 170ml chilled sparkling water.
Can I add sugar to matcha soda?
Yes. Dissolve a small amount of brown sugar in the warm matcha base before it reaches the sparkling water. Start small so the sweetness does not cover the matcha.
Why did my matcha soda go flat?
Vigorous stirring, warm sparkling water or too little ice can reduce the fizz. Keep the soda chilled, pour gently and stir only once or twice.
