Plain matcha does not contain added sugar.
A basic matcha made with pure matcha powder and water is unsweetened, but matcha lattes and café drinks may contain sugar from milk, syrups, sweeteners or premixed powders.
Pure Matcha Is Not Pre-Sweetened
Pure matcha is finely ground green tea. It can taste grassy, creamy, savoury, rich or slightly bitter depending on the matcha, but sugar is not a required ingredient.
When you whisk pure matcha with water, you control everything that goes into the cup. There is no added sugar unless you choose to add honey, maple syrup, simple syrup or another sweetener.
This is different from some products labelled as a “matcha mix.” These may combine a small amount of matcha with sugar, milk powder, or flavouring. Check the ingredient list rather than assuming every green powder is pure matcha.
Why Café Matcha Drinks Can Be So Sweet
A matcha latte from a café can be a very different drink from plain matcha. The matcha itself may be unsweetened, but the finished drink can include several sources of sugar:
- Simple syrup or flavoured syrup
- Honey, maple syrup, or liquid cane sugar
- Sweetened dairy or plant-based milk
- Vanilla, strawberry, or other flavouring
- A premixed matcha powder that already contains sugar
Some cafés sweeten matcha automatically because the sugar softens its bitterness. Others use pure matcha and let customers choose the sweetness.
Milk Can Add Naturally Occurring Sugar
Even when no syrup is added, a matcha latte may still contain sugar from the milk. Dairy milk naturally contains lactose, while plant-based milks can contain naturally occurring or added sugars depending on the product.
“Unsweetened” milk usually means that no sugar has been added, but the nutrition label may still show some total sugar. Oat milk, almond milk, soy milk and coconut beverages can differ considerably, so check the carton when making matcha at home.
How to Order a Lower Sugar Matcha
When ordering at a café, ask whether the matcha powder is pure or already sweetened. This matters because requesting “no syrup” will not remove sugar that is already blended into the powder.
You can also ask for the drink unsweetened, half-sweet or with the sweetener served separately. Choosing an unsweetened milk gives you more control, especially when the café normally uses a sweetened plant-based option.
For flavoured matcha drinks, remember that fruit purées, sauces, cold foams and toppings may add sweetness even when the matcha base is unsweetened.
Making Matcha at Home Gives You More Control
At home, start by whisking pure matcha with a small amount of hot water. Add water or milk, taste the drink, and then decide whether it needs sweetener.
A small amount is often enough. Starting with half a teaspoon lets you soften the stronger green tea notes without turning the drink into a dessert. You can always add more, but you cannot remove it once it is mixed in.
Know Where the Sweetness Comes From
Matcha does not need sugar, but many matcha drinks include it.
The most reliable approach is to check whether the powder is pure, ask what is added at the café and choose your milk and sweetener deliberately. That way, your matcha can be completely unsweetened, lightly sweet or made exactly to your preference.
