Matcha is loved for its wellness benefits and unique taste—but what about calories? Here’s how many calories are in matcha powder and a matcha latte, how to reduce them, and why choosing organic matcha matters.
Pure matcha is one of the lowest-calorie drinks out there, with only around 3 kcal per 1-gram serving. This low calorie count comes from the fact that high-quality matcha contains no added sugar and no additives: it’s simply shade-grown green tea leaves (tencha) finely ground into a powder. Those ~3 calories mainly come from the natural carbohydrates and fibre found in the whole leaf—which you actually consume when you drink matcha.
You’ll sometimes see matcha described as a “negative-calorie drink”. In reality, it’s best to see this as a metabolism-supporting beverage rather than a miracle claim: matcha’s catechins (including EGCG) may support energy expenditure when taken before exercise, but results vary from person to person and depend on lifestyle.
| Serving | Energy | Carbs | Fibre | Protein | Fat |
|---|---|---|---|---|---|
| 1 g of pure matcha | ~3 kcal | ~0.4 g | ~0.3 g | ~0.3 g | ~0.0 g |
| 100 g (powder) | ~300 kcal | ~40 g | ~30 g | ~30 g | ~5 g |
Average indicative data — it varies depending on origin and grade. Matcha is consumed in small amounts (1–2 g).
Watch out for “matcha latte mixes” sold commercially. Many contain added sugar, fillers, and sometimes flavourings. That can dramatically increase calories. In comparison, real organic ceremonial matcha is naturally sugar-free and low in calories—perfect if you want a clean, balanced routine.
A matcha latte adds calories mainly because of the milk. The good news: by choosing lower-calorie, unsweetened milks, you can enjoy a matcha latte without meaningfully impacting your daily intake.
Here are example calorie ranges for homemade matcha lattes (based on a 240 ml cup):
For an overview, here’s a comparison table of homemade vs coffee shop matcha lattes:
| Matcha latte type | Calories (per 240 ml cup unless stated) | Added sugar |
|---|---|---|
| Homemade – almond milk | 35 kcal | No |
| Homemade – oat milk | 45 kcal | No |
| Homemade – soy milk | 45 kcal | No |
| Homemade – coconut milk | 140 kcal | No |
| Homemade – rice milk | 70 kcal | No |
| Homemade – whole milk | 68 kcal | No |
| Starbucks (473 ml, soy) | 154 kcal | Yes (10.8 g) |
| Dunkin’ (16 oz, oat) | 240–340 kcal | Yes |
| Generic chain (230 ml) | 175 kcal | Yes (28 g) |
In cafés, matcha lattes are popular—but they’re often much higher in calories than homemade. The reason is simple: many coffee shops use sweetened matcha powders, syrups, or added sugar to soften the taste.
For example, a large (473 ml) soy matcha latte at Starbucks contains 154 kcal, including 10.8 g of added sugar. Likewise, a small iced matcha (16 oz) at Dunkin’ made with oat milk can reach 240–340 kcal, depending on the sweetened mix used. Some chains even go up to 175 kcal and 28 g of sugar for a 230 ml serving. If you want full control, the easiest solution is a homemade matcha latte.
Homemade matcha lattes let you pick quality ingredients and avoid unnecessary extras. Use traditional tools like a chasen (bamboo whisk) and a chawan (matcha bowl) for a silky foam—without additives.
Quick formula: Total calories = 3 kcal × grams of matcha + milk calories (by type & volume) + any sweeteners. Example: 1 g matcha + 240 ml unsweetened almond milk (~35 kcal) + 0 sugar = ~38 kcal.
Whether you choose oat, almond, soy, coconut, or rice milk, adjust quantities and prioritise unsweetened versions for a lighter, still delicious latte. With high-quality matcha, bitterness is naturally lower—meaning you’ll feel less need to add sugar. Follow our matcha latte recipe for hot or iced versions.
If you want a touch of sweetness, choosing the right sweetener helps limit calories and reduce blood sugar spikes.
In short, a matcha latte can stay relatively low in calories while still delivering flavour and micronutrients. Compared to many sweet hot drinks, a matcha latte made with unsweetened milk and no added syrup is a lighter alternative.
Matcha contains around 35 mg of caffeine per gram, paired with L-theanine for a steadier, calmer lift. For the smoothest experience, try our Organic Ceremonial Matcha and follow our homemade matcha latte recipe.
