Calories in espresso (espresso)
Calories, protein, carbohydrate and fat per 100 g and per serving, from the USDA reference database — plus what actually changes the number on your plate.
Short answer
100 g of espresso (espresso) contains 9 kcal, with 0.1 g of protein, 1.7 g of carbohydrate and 0.2 g of fat.
A typical serving — 1 shot, about 30 g — is roughly 3 kcal.
That makes it a low-calorie food: you can eat a large portion for very little.

Where the calories come from
Calories come from three macronutrients: protein and carbohydrate at 4 kcal per gram, fat at 9 kcal per gram. For espresso (espresso) the split is:
- Protein: 0.1 g × 4 = 0 kcal — 5% of calories
- Carbohydrates: 1.7 g × 4 = 7 kcal — 76% of calories
- Fat: 0.2 g × 9 = 2 kcal — 18% of calories
- Most of the energy in espresso (espresso) comes from carbohydrate (76% of calories).
- It is 98% water, which is why it is so light for its size.
- For 200 kcal you can eat about 2,220 g.
Compare preparations
The same food, prepared differently. Cooking removes water (so calories per 100 g rise), adds fat (so they rise further), or both.
| Preparation | Calories | Protein | Carbohydrates | Fat |
|---|---|---|---|---|
| Coffee (black, brewed) | 1 | 0.1 g | 0 g | 0 g |
| Espresso (espresso)this page | 9 | 0.1 g | 1.7 g | 0.2 g |
What actually changes the number
A shot of espresso is about 3 kcal. A cappuccino is 60–120 kcal depending on milk; a flat white about 120; a mocha 250–350.
How accurate are these numbers?
The values on this page are reference averages from the USDA FoodData Central database (SR Legacy release), measured on samples of espresso as sold and prepared in the United States. Your portion will differ: produce varies by variety and ripeness, meat by cut and trim, and anything cooked by the fat and water it gained or lost.
For most foods the per-100 g figure is reliable to within about 10%. The larger uncertainty is almost always the weight of what is on your plate and the cooking fat you cannot see — the two things worth checking before you worry about the database.
