One cup of regular black coffee brewed from ground beans holds only 2 calories, and 1 fluid ounce of rich black espresso contains only 1 calorie. Also A 1 mug/270 ml of black coffee contains about 5.4 calorie. One teaspoon of regular instant coffee powder also carries just 2 calories. Brewing coffee from decaffeinated beans reduces the calorie count to zero, but decaffeinated coffee powder doubles the calories found in 1 teaspoon to 4. Sweeteners, flavorings and cream or milk deliver the calories in rich modern coffee drinks, some of which may yield 700 calories per serving.
