Atomy’s Korean Cafe Arabica Zero Sugar listing gives 3,500 kcal for a pack of one hundred 10 g sticks. Dividing the pack total by the stick count gives 35 kcal per stick.
| Coffee used, with water only | Calculation | Energy from the coffee product |
|---|---|---|
| One complete stick | 3,500 ÷ 100 | 35 kcal |
| Two complete sticks | 35 × 2 | 70 kcal |
“Zero Sugar” and “zero calories” are different statements. An energy claim about a sweetening ingredient must not be substituted for the completed product’s nutrition information.
A larger cup does not erase the stick’s calories
If you put the whole stick in a cup and add more water, you change the concentration and drink volume. The amount of coffee product remains one stick.
If you add milk or another ingredient, include that ingredient’s quantity and nutrition information as well. Cup size alone is not an energy calculation.
The Korean preparation directions use one stick with 100 mL of hot water. Whether you follow that amount or compare a different concentration, count the sticks actually used.
Compare the same amount
To compare with another coffee mix, first align the serving basis. One stick may weigh a different amount from another brand’s stick.
You can compare per serving or per common weight, but label which basis you chose. If you then drink a complete stick, record the complete serving rather than a smaller comparison unit.
The name does not settle every dietary question
The ingredient information declares milk. Someone with a milk allergy should not choose this product based on its sugar-related name.
The same name also does not establish unrestricted suitability for a medical condition or make the drink a substitute for personalised dietary advice.
For an ordinary shopping comparison, the useful starting point is concrete: one full stick contributes 35 kcal according to this Korean pack’s stated total, before any additional ingredients.
