Coffee Calories: How Many in Espresso, Latte & More

You’ve heard coffee can help with weight loss—but is that true if your daily cup has hundreds of calories? With so many coffee styles out there, figuring out which ones won’t undo your diet isn’t always easy. This guide lays out the facts so you know exactly what you’re drinking.

Quick answer: A plain black coffee (100g) has just 5 kcal, while an espresso (about 30ml) has around 117 kcal without sugar or milk. A latte racks up 220 kcal mainly from milk, and a mocha can hit 235 kcal due to added chocolate. Skip the sugar and milk, and you can enjoy coffee with almost no impact on your calorie intake.

What Is an Espresso and How Many Calories Does It Have?

An espresso, typically made using a moka pot (the Italian invention that forces steam through coffee grounds), is known for its strong flavor, bold bitterness, and thin layer of crema on top. This crema comes from the coffee’s natural oils and contributes to its rich aroma. While brewing with a moka pot uses steam pressure to extract the coffee, the result is similar in strength and texture to espresso shots.

A standard espresso (not specified in volume but roughly 30ml as a single shot) has approximately 117 kcal, assuming no sugar or milk is added. That makes it a low-calorie choice on its own.

How Many Calories in Black Coffee?

Black coffee—just ground coffee and hot water—is the simplest and lowest-calorie coffee option. A 100g serving contains just 2.55 kcal. For even better results, drink it hot: heat can slightly boost your metabolism, helping burn more calories. Also, lighter roasts (such as those used in American-style black coffee) tend to be more effective for weight management compared to darker roasts, which may have less caffeine and more body but don’t support fat burning as efficiently.

To sum up: black coffee has only about 5 kcal per serving, making it almost calorie-free.

Calories in a Latte – Why It’s Higher

A latte consists of a small shot of espresso combined with a large amount of steamed milk and a layer of milk foam. The standard preparation involves pouring about one quarter espresso and three quarters hot milk with foam into a mug. Because of the high milk content, lattes are usually served in larger cups like mugs.

The calorie count for a typical latte is around 220 kcal. This is primarily due to the milk, which adds both calories and creaminess. If you're watching your calorie intake, opting for skimmed milk or keeping the portion smaller can help reduce the total.

Mocha: Chocolate Adds Significant Calories

A mocha takes the classic latte and adds chocolate, making it a favorite for those with a sweet tooth. This drink combines espresso, steamed milk, and chocolate syrup or cocoa, often topped with whipped cream in some versions.

Due to the added chocolate, a mocha typically contains about 235 kcal. That makes it the most calorie-dense option among the common coffee drinks listed here. If you’re trying to limit calories, it’s best to enjoy mochas as an occasional treat rather than a daily habit.

Frequently Asked Questions

How many calories are in a plain espresso shot?

A standard espresso shot (approx. 30ml), with no added sugar or milk, contains around 117 calories. This estimate applies to coffee brewed using methods like a moka pot, which produces a concentrated shot similar to espresso.

Is black coffee really low in calories?

Yes. A 100g serving of black coffee has about 2.55 kcal, which rounds to roughly 5 kcal per normal serving. It’s one of the lowest-calorie beverage options available.

Why does a latte have so many calories?
