About Espresso Shot

A one-fluid-ounce restaurant-style espresso shot provides approximately 3 calories, 0.1 grams of protein, 0.5 grams of carbohydrate, a trace amount of fat, and no fiber. Plain espresso therefore has essentially no glycemic effect from carbohydrate.

Espresso is more concentrated than ordinary brewed coffee by volume. A standard shot supplies about 64 milligrams of caffeine together with magnesium, potassium, niacin, riboflavin, and coffee polyphenols, although values vary with bean, roast, dose, extraction time, and shot volume.

This entry represents espresso alone. Sugar, flavored syrup, whipped cream, chocolate, and milk can increase calories substantially, while an Americano made only with water keeps approximately the same nutrition as its espresso shots.

Expert Tip

Drink espresso plain to keep its calorie count minimal. Caffeine is concentrated in a small volume, so count shots rather than cup size and avoid adding multiple late-day shots if they reduce sleep quality or trigger anxiety, reflux, tremor, or palpitations.
