Quick Answer: An espresso is a small, concentrated shot of coffee (2–3 oz) brewed by forcing hot water through finely ground beans — intense, bold, and served plain. A latte is built on that same espresso shot but adds a large amount of steamed milk (about a 1:3 ratio) plus a thin layer of foam, served in an 8–16 oz cup. In short, milk is the difference: a latte is roughly 60–75% steamed milk, while an espresso contains none.

What Is Espresso?
Espresso is coffee in its most concentrated form. It is made by forcing nearly boiling water through finely ground coffee beans at high pressure — typically 9 bars — for about 25–30 seconds. The result is a small 1–2 oz shot (a double shot is 2–3 oz) topped with crema, the golden-brown foam that signals a well-pulled shot.
Because the water passes through the grounds so quickly and under pressure, espresso extracts intense flavor: bold, rich, and slightly bitter, with the coffee’s natural oils intact. It is the foundation of almost every café drink — lattes, cappuccinos, macchiatos, and mochas all start with espresso shots.
Espresso originated in Italy in the early 20th century, where the word roughly means “pressed out” — coffee made expressly for you, fast. Traditional Italian café culture treats it as a quick stand-up drink: order, drink in two or three sips, and go. To understand where espresso fits among brewing methods, the National Coffee Association’s coffee guide offers a solid overview of coffee types and preparation.
What Is a Latte?
A latte — short for caffè latte, Italian for “milk coffee” — is an espresso shot mellowed by a generous pour of steamed milk and finished with a thin layer of foam. The standard ratio is about one part espresso to three parts steamed milk, which means a 12 oz latte contains roughly 8–9 oz of milk.
The milk transforms the drink. Steaming heats the milk to around 150°F (65°C) and creates a silky texture called microfoam, which softens espresso’s bitterness and adds natural sweetness from the milk sugars. Baristas often pour latte art — hearts, rosettas, tulips — into the foam, which is possible because of the drink’s high milk content.
The latte belongs to a crowded family of espresso-and-milk drinks — cappuccino, flat white, cortado, macchiato — that are easy to confuse at a glance. Telling them apart mostly comes down to milk ratios, just as two similar-looking foods can differ in composition; for a fun food-world parallel, see our cavatappi vs cellentani comparison. Among the family, the latte is the milkiest and mildest.
The Milk Factor
Milk is the single defining difference between the two drinks. An espresso contains zero milk — it is pure coffee, water, and crema. A latte is 60–75% steamed milk by volume. Everything else about the experience flows from that one fact.
The milk does three things. First, it dilutes the espresso, spreading the same amount of coffee flavor across a much larger drink. Second, steaming changes the milk itself: heat breaks down lactose into sweeter-tasting sugars, which is why a latte tastes naturally sweet even with no added sugar. Third, the milk’s proteins and fats create a creamy mouthfeel that espresso’s thin, intense body cannot match.
This is also why lattes are so customizable. Swap whole milk for oat, almond, or soy and the flavor shifts noticeably. Espresso offers no such lever — its taste depends entirely on the beans, the grind, and the barista’s technique. If someone says they dislike the taste of coffee but enjoys lattes, the milk is doing the heavy lifting.
Size and Serving Style
An espresso arrives in a tiny demitasse cup — 2 to 3 ounces — and is meant to be drunk in a few sips, often standing at an Italian bar. It is a quick, concentrated ritual: the whole drink can be gone in under a minute.
A latte is a full-sized beverage: 8 oz at the smallest, more commonly 12–16 oz in American cafés, served in a tall glass or wide mug. It is designed for lingering — sipping over a conversation, a work session, or a commute. The larger vessel also gives baristas room for latte art.
Glassware matters more than it seems. Espresso’s small cup keeps the shot hot and concentrates its aroma; a wide latte mug lets the milk cool to a drinkable temperature and shows off the foam art. When you order, size is the fastest way to tell drinks apart on a menu: anything 2–3 oz with no milk mentioned is espresso territory, while the 12 and 16 oz options are almost always milk-based.
Caffeine Content Compared
Here is the surprise: a single-shot latte has about the same caffeine as a single espresso — roughly 63–68 mg. Both drinks start from the same shot; the latte just adds milk around it. Milk dilutes flavor, not caffeine.
What changes the caffeine is the number of shots. A double espresso (doppio) contains about 126 mg of caffeine. A latte made with two shots contains the same 126 mg. Many cafés pull double shots as their standard for milk drinks, so a “regular” 12 oz latte often has more caffeine than a single espresso — not because it is a latte, but because it contains two shots.
If caffeine is your main concern, count shots, not drink names. Ask your barista how many shots go into each size: a single-shot 8 oz latte and a double-shot 16 oz latte can differ by a factor of two. Decaf shots are available for both drinks and work exactly the same way.
Taste Profile
Espresso tastes like coffee turned up to maximum volume: bold, intense, and concentrated, with notes that range from chocolatey and nutty to fruity and bright depending on the beans. The crema adds a slightly bitter, aromatic top layer. Because there is nothing to hide behind, flaws show immediately — a bad shot tastes sour or ashy.
A latte tastes like coffee softened by milk: mellow, creamy, and naturally a little sweet. The espresso’s sharper edges — bitterness, acidity — are rounded off by the milk’s fats and sugars. You still taste coffee, but it is a background note rather than the whole show.
Preference here is purely personal. Coffee purists who want to taste the bean itself choose espresso; those who find straight espresso too harsh choose lattes. Neither is stronger in caffeine at the same shot count — the latte only tastes weaker because its flavor is spread through milk.
Calories and Nutrition
A plain espresso is nearly calorie-free: about 3–5 calories per shot, with negligible fat, sugar, or carbs. It is one of the lowest-calorie ways to drink coffee.
A latte’s calories come almost entirely from milk. A 12 oz latte made with whole milk contains roughly 120–190 calories, plus natural milk sugars (lactose). Switch to skim milk and it drops to around 70–100; oat milk lands in a similar range to whole milk, while almond milk is the lightest at roughly 60–80.
Flavored syrups change the math dramatically — a vanilla or caramel latte can add 50–100 calories per pump. If you are watching calories, order the latte with skim or almond milk and skip the syrup, or simply drink the espresso. Those avoiding dairy for dietary reasons often choose plant milks; if you are sorting out the terminology, our vegan vs vegetarian comparison explains how those diets differ.
Cost and How to Order
At most cafés, an espresso costs less than a latte — typically $2–4 versus $4–6 — because it is smaller and uses no milk. The latte’s price reflects more ingredients, more labor (steaming and pouring), and a bigger cup.
Ordering an espresso is simple: ask for a single or a double (“doppio”). It arrives quickly with no customization needed. Ordering a latte involves choices: size (8, 12, or 16 oz), milk type (whole, skim, oat, almond, soy), number of shots, and any syrups. If café menus feel overwhelming, you are not alone — sandwich counters can be just as confusing, which is why we wrote our sub vs hoagie comparison for deli-menu dilemmas.
Prices vary by country: expect to pay a few dollars in the US or a few pounds in the UK — and if you hear a Brit call it “quid,” our pounds vs quid comparison explains the slang. Either way, the latte will cost more than the espresso on the same menu.
Which One Should You Choose?
Choose espresso if you love the pure taste of coffee, want your caffeine fast, and prefer the lowest-calorie option. It is the purist’s drink: no milk, no distractions, just the bean and the barista’s skill. It is also the budget pick and the quickest order.
Choose a latte if you find straight espresso too intense, enjoy a creamy texture, or want a drink you can sip slowly. It is more filling, more customizable, and more forgiving — mediocre espresso can hide behind good milk, which is not true in reverse.
Match the drink to the moment: an espresso for a quick morning jolt or an after-dinner finish, a latte for a long café work session or a gentle introduction to coffee. Being clear about what you want from the cup makes the choice easy — the same clarity our friendship vs relationship comparison brings to personal connections. There is no wrong answer, only the drink that fits your taste, your budget, and your day.
Frequently Asked Questions
Does a latte have more caffeine than an espresso?
Not necessarily. A single-shot latte and a single espresso both contain about 63–68 mg of caffeine because they start from the same shot. Many cafés use double shots in lattes, which raises the total to about 126 mg — but that is the extra shot doing the work, not the milk.
Is a latte just espresso with milk?
Essentially, yes — plus technique. A latte is espresso combined with steamed milk (about a 1:3 ratio) and a thin layer of foam. The steaming matters: properly textured milk adds sweetness and a silky mouthfeel that simply pouring cold milk into coffee cannot replicate.
Which has more calories, espresso or latte?
The latte, by a wide margin. A plain espresso has about 3–5 calories, while a 12 oz whole-milk latte has roughly 120–190. Almost all of the latte’s calories come from the milk, so choosing skim or almond milk — and skipping syrups — brings it down significantly.
What is the ratio of espresso to milk in a latte?
The standard ratio is about 1 part espresso to 3 parts steamed milk, topped with a thin layer of foam. In a 12 oz latte, that works out to roughly 2 oz of espresso (a double shot) and 8–9 oz of milk. Cafés vary, but 1:3 is the benchmark.
Can I make a latte without an espresso machine?
Yes, with compromises. Brew very strong coffee with a moka pot, AeroPress, or concentrated French press, then add hot steamed or frothed milk — a handheld frother or even a whisk works. It will not have true espresso’s crema or intensity, but it captures the latte’s creamy character.
Conclusion
The difference between espresso and latte comes down to one ingredient: milk. Espresso is pure, concentrated coffee in a 2–3 oz shot; a latte takes that same shot and mellows it with 60–75% steamed milk. Caffeine depends on the number of shots, not the drink name. Choose espresso for intensity and simplicity, a latte for creaminess and comfort — and now you can order either with confidence.
