What Is a Latte? Definition, Taste, Milk Ratio, and Variations

The café latte (or simply latte) is one of the most beloved espresso drinks around the world. At its core, a latte is a combination of espresso and steamed milk, topped with a small layer of milk foam. The result is a smooth, creamy coffee beverage that’s more milk-forward than other espresso-based drinks. In fact, the Italian name caffè latte literally means “coffee with milk”.

Lattes are enjoyed for their mellow flavor and are often adorned with beautiful latte art – those heart or flower designs in the foam – making them as pleasing to the eye as they are to the palate.

(Fun fact: In Italy, if you just order a “latte,” you’ll get a glass of milk, so be sure to ask for “caffè latte” when abroad!)

A classic latte served in a small glass, showcasing the signature heart-shaped latte art on its creamy foam. This page is the core latte definition on The Golden Lamb Coffee, covering the drink’s standard formula, taste, milk ratio, and the variations most people actually mean when they order a latte.

For side-by-side drink decisions or Starbucks-specific questions, use the dedicated comparison and FAQ pages linked later in this guide. Here, the goal is to make the latte itself clear first.

What Is a Latte?

A latte is a creamy espresso drink made with 1–2 shots of espresso, steamed milk, and a thin layer of foam. With a typical 1:3 espresso-to-milk ratio, it’s smoother and milder than other espresso drinks like macchiatos or straight shots. The steamed milk softens the coffee’s intensity, creating a rich, mellow flavor.

In fact, coffee experts note that a latte has a “more mild, slightly sweet flavor” since the higher proportion of milk softens the intensity of the espresso. The milk also gives the drink a velvety body and an approachable flavor profile that many find comforting.

Serving: A traditional latte is usually served in an 8 oz to 12 oz cup (or glass), making it one of the larger espresso drinks. Many cafés present lattes in a tall glass tumbler, which makes it visually distinct from a cappuccino (often in a smaller cup) or a flat white.

The top is crowned with a thin layer of microfoam – just enough foam to allow for latte art, but not as thick a foam layer as a cappuccino. Thanks to this velvety milk foam, baristas can create hearts, rosettas, and other latte art on the surface, adding to the latte’s appeal.

How Is a Latte Made?

Making a latte involves a few simple components and steps. Here’s how a barista typically crafts a latte:

1. Espresso as the Base

Lattes start with 1–2 shots of espresso, brewed by forcing hot water through finely-ground coffee under pressure. This concentrated coffee gives the drink its bold flavor. At home, you can use an espresso machine, Moka pot, or strong brewed coffee.

2. Steamed Milk

Milk is steamed with a steam wand to create smooth, velvety microfoam. For a latte, the milk should be mostly liquid with a thin foam layer on top. Whole milk is common, but any type works.

3. Pouring and Latte Art

Steamed milk is poured into the espresso to blend the two. Baristas often tilt the cup and finish with simple foam art. The goal is a creamy drink with a uniform taste and a light foam finish.

A barista pours steamed milk to create latte art—a sign of well-textured microfoam and good technique. It’s not just for show; microfoam blends smoothly with espresso. No latte art? No problem—your drink will still taste great.

Milk Choices & Foam Texture

Milk type impacts both flavor and foam. Whole milk is popular for its creamy texture and shiny, velvety microfoam—ideal for latte art. Skim milk creates more foam but with larger bubbles and a drier feel.

Skim is easier to froth, but whole milk gives that classic, rich latte texture. The key is microfoam: a thin, silky layer that blends smoothly with the milk.

Aim for 150–160°F when steaming. Too much foam? You’ve got a cappuccino. Too little? It’s closer to a flat white. A well-made latte lands right in between.

What Does a Latte Taste Like?

A latte is often described as rich, creamy, and mellow. Thanks to the large proportion of milk, the espresso’s bitterness is softened significantly. The flavor is coffee-like but not overpowering, with a natural sweetness coming from the lactose in milk (even with no sugar added, milk has a bit of sweetness). Here are some key points about a latte’s flavor and mouthfeel:

Mild Coffee Flavor

The espresso provides a coffee flavor, but in a latte it isn’t as intense as in smaller drinks. The milk dilutes the bitterness and intensity of the espresso, resulting in a smooth, mild coffee taste. Many people who find straight espresso too strong enjoy the gentler flavor of a latte. You’ll still taste the roasty notes of the coffee, but without the harsh edge.

Creamy and Velvety

The texture of a latte is one of its highlights. It feels creamy and full-bodied due to the steamed milk. When made correctly, a latte has a velvety mouthfeel – think of the texture of warm, thick milk with a light froth.

This creaminess makes it comforting and easy to drink. Coffee aficionados note that a latte’s “smooth, creamy taste” is a big part of its appeal.

Slight Sweetness (No Syrup Needed)

Even if you don’t add any sugar or flavored syrup, a latte can taste slightly sweet. This sweetness isn’t from added sugar, but from the natural sugars in milk (lactose). Steaming the milk can make its inherent sweetness more pronounced.

So a plain latte has a gentle sweetness and isn’t as bitter as black coffee. Of course, you can always add sugar or flavor if you prefer, but a traditional latte is often enjoyed as-is for a more subtle taste.

Low Bitterness

Because it’s so milk-forward, a latte has very low bitterness compared to drip coffee or straight espresso. The milk fat and proteins bind with some of the bitter compounds in espresso, mellowing them out.

The result is a very approachable flavor even for those new to coffee. If you find a cappuccino or straight coffee too sharp, a latte might be the perfect balance for you.

In summary, expect a latte to taste creamy, lightly sweet, and coffee-flavored but not too strong. It’s often likened to a “warm hug in a cup” because of its comforting, milky character. This flavor profile makes the latte a great canvas for additional flavors, which leads us to the next topic: flavored latte variations.

Popular Latte Variations and Flavors

One reason lattes are so popular is that they are incredibly versatile. The classic latte (just espresso and milk) is delicious on its own, but it also serves as the base for many flavored drinks.

By adding syrups, sauces, or other ingredients, you can create a whole menu of latte variations. Here are some of the most popular latte flavors and customizations:

Vanilla Latte

A shot of vanilla syrup added to the latte turns it into a vanilla latte. This is one of the most popular flavored lattes. The vanilla adds a sweet, fragrant note that pairs well with the milk and coffee. Many coffee shops use classic vanilla syrup – a simple syrup infused with vanilla flavor.

Caramel Latte / Caramel Macchiato

Drizzles of caramel or pumps of caramel syrup give a latte a buttery sweetness. Starbucks made the Caramel Macchiato famous – which is essentially a vanilla-flavored latte with caramel sauce.

Despite the name “macchiato,” the Starbucks Caramel Macchiato is built like a latte with flavored syrup and caramel drizzle. A caramel latte typically has rich caramel sweetness throughout.

Mocha Latte (Caffè Mocha)

A mocha is basically a chocolate-flavored latte. It’s made by adding chocolate syrup or cocoa powder to the espresso and milk. The result is a sweeter, dessert-like drink that tastes like hot chocolate meets coffee. Mochas often come topped with whipped cream in coffee shops.

If you love chocolate, this is your latte upgrade.

Hazelnut or Other Nutty Lattes

Hazelnut latte, made with hazelnut syrup, is another café staple, offering a nutty sweetness. Similarly, almond, toffee nut, or even pistachio flavor syrups can create unique latte experiences.

Seasonal Specials (Pumpkin Spice Latte, etc.)

Every fall, the famous Pumpkin Spice Latte (PSL) makes its appearance, combining espresso, milk, and a pumpkin spice syrup (with cinnamon, nutmeg, etc.) for a cozy seasonal treat.

Beyond pumpkin spice, cafés experiment with gingerbread lattes in winter, peppermint mochas around the holidays, and other seasonal specialties. These usually include special flavored syrups and often come with whipped cream or toppings.

Dirty Chai Latte

This popular hybrid is actually a tea-coffee combination. A chai latte is made with spiced chai tea concentrate and milk (no espresso). Add a shot of espresso to that, and you have a Dirty Chai – effectively a chai tea latte with an espresso kick.

It’s not a traditional caffè latte since it involves tea, but you’ll see it on many coffee shop menus.

Other “Lattes”

The term “latte” has broadened in casual use to include drinks that don’t contain coffee at all, as long as they have a milk + something + foam format.

Examples include the Matcha Latte (made with green tea matcha powder, milk, and often a sweetener), Turmeric Latte (a.k.a. golden milk, with turmeric and spices), and Chai Latte (spiced black tea with milk).

These are technically not caffè lattes (since there’s no espresso), but the preparation with steamed milk is similar, so they’ve adopted the latte name.

When adding flavors to a latte, remember the extra ingredients can change the nutrition. Syrups add sugar (a typical flavored syrup pump can add ~5 grams of sugar per pump). For example, a flavored 12 oz vanilla latte might have 2–4 pumps of syrup, adding a significant amount of sugar and calories.

Many coffee chains also offer “skinny” latte options – usually meaning made with skim milk and sugar-free syrup to reduce calories.

According to coffee historians, flavored lattes really boomed in popularity in the late 20th century as coffee culture grew.

By the 1980s and 90s, cafés were offering vanilla, mocha, and other flavored lattes to appeal to those with a sweet tooth. Today, the latte is an evolving canvas – baristas and home enthusiasts alike experiment with new flavors all the time.

Milk Options and Substitutions for Lattes

While whole dairy milk is the classic choice for a latte, there are many reasons someone might use a different kind of milk. Maybe you’re lactose intolerant, vegan, or just looking to cut calories – whatever the reason, you can still enjoy a delicious latte with various milk alternatives.

Each type of milk (dairy or non-dairy) can affect the taste, texture, and nutrition of the latte. Let’s explore some common milk options:

Whole Milk

This is the default in many coffee shops (though some use 2%). Whole milk gives the richest, creamiest flavor and mouthfeel because of its higher fat content—about 3.5% fat. It also creates nicely textured foam.

An 8 oz cup of whole milk contains roughly 150 calories and 8g of fat. Lattes made with whole milk will be creamy and satisfying, but they’re higher in calories than those made with leaner milk.

Reduced-Fat Milk (2% or 1%)

Many cafés, including Starbucks in the U.S., use 2% milk by default. It offers a good balance: some fat for flavor, but fewer calories than whole milk. A cup of 2% milk has around 120 calories, and it still produces a creamy latte with decent foam.

Skim milk (0% fat) has about 80 calories per cup and no fat, resulting in a much lighter latte. The foam from skim milk tends to be larger-bubbled and more airy—like meringue—rather than silky.

While skim milk can actually produce more foam due to its higher protein ratio, the texture is drier and less rich. Skim milk lattes, often called “skinny lattes,” are a popular low-calorie option. Many latte drinkers choose 2% or 1% as a middle ground for creaminess and calorie control.

Non-Dairy Milk Alternatives

In recent years, plant-based milks have become extremely popular in lattes. You can request almond, soy, oat, coconut, and others at most coffee shops now. Here’s how they compare:

Almond Milk

Almond milk is much lower in calories than dairy milk—unsweetened almond milk is often only 30–50 calories per cup—making it a lighter option for lattes. The flavor is slightly nutty and the texture can be thin.

Almond milk typically produces foam that is less stable and not as creamy due to its low protein content. Many cafés use “barista blend” almond milk, which includes additives to help it foam better. If you use regular almond milk, expect a more watery texture and quickly dissipating foam.

Taste-wise, the nuttiness is mild and often overpowered by the espresso. It’s a popular choice for those watching calories or avoiding dairy.
(Calories: ~40 per 8 oz unsweetened; Protein: low (~2g); Fat: ~3g)

Soy Milk

Soy milk was the original non-dairy alternative in most cafés. It has a thicker body than almond milk and is higher in protein, which helps it create a stable foam—closer to dairy milk in performance.

Unsweetened soy milk has around 80–90 calories per cup, similar to skim milk. It brings a distinct flavor—sometimes described as bean-like or malty—but this is often masked in flavored lattes.

While soy can foam well, some types curdle when combined with acidic espresso; barista-formulated soy milks are designed to avoid this issue.
(Calories: ~80 per 8 oz; Protein: ~7g; Fat: ~4g)

Oat Milk

Oat milk has become a favorite in recent years thanks to its naturally sweet taste and creamy texture. It performs well in lattes, especially barista editions formulated for steaming.

Oats contain natural sugars, lending a subtle sweetness, and barista blends often include a bit of oil to improve mouthfeel and emulsification.

Oat milk lattes are smooth and slightly reminiscent of oatmeal cookies. It’s one of the best dairy-free options for latte art due to its ability to texture like milk.
(Calories: ~120 per 8 oz; Protein: ~3g; Fat: ~5g)

Coconut Milk

Coconut milk for drinking (not the canned kind) is light at around 50 calories per cup, but it has a thin consistency and foams poorly due to almost no protein.

Its flavor is distinctly coconutty, which can be polarizing—it adds a sweet, tropical note that can overwhelm the coffee. While available in some major chains, coconut milk lattes tend to have flatter texture and muted espresso flavor.
(Calories: ~50 per 8 oz; Protein: ~0g; Fat: ~5g)

Others

Other options include rice milk (very sweet, high in carbs, no protein, poor for foaming), hemp milk, cashew milk, macadamia milk, and even goat’s milk.

Rice milk is especially thin and doesn’t foam well. Cashew and hemp milk can be creamier, but they’re less commonly found in coffee shops. Goat’s milk is rare and has a tangy taste that’s not for everyone.

Using Alternative Milks

If you use a non-dairy milk at home, you might notice it’s harder to achieve that silky microfoam. Many companies now produce “Barista Blend” non-dairy milks—such as oat, almond, or soy—that include stabilizers to help the milk froth and emulsify more like dairy.

If you’re serious about non-dairy latte making, look for these versions. For example, barista oat milk can create foam suitable for latte art that’s almost indistinguishable from cow’s milk.

Taste and Nutrition Differences

Changing the milk changes the latte’s overall character. A whole milk latte will be rich and naturally sweet. A skim milk latte is lighter in body and a bit less flavorful, but it allows the espresso’s flavor to come through more clearly.

Oat milk may taste sweeter or have a cereal-like flavor, while almond milk introduces a light nuttiness and a thinner mouthfeel.

Nutritionally, switching from whole milk to skim or plant-based milk can cut calories significantly. Whole milk has about 150 calories and 8g of fat per cup.

Unsweetened almond milk, by comparison, can be as low as 30–40 calories with zero sugar. That’s a savings of roughly 100 calories per cup when swapping from whole to almond milk.

Soy milk is nutritionally closer to dairy, offering similar protein levels. Almond and coconut milk are lower in protein and better suited for those prioritizing calorie reduction over nutritional content.

Final Thoughts on Milk Choices

There’s no wrong choice—it all comes down to your dietary needs and taste preferences. Many beginners try a few different milks before settling on a favorite. Pro tip: if you’re trying a non-dairy latte for the first time, start with oat milk.

It’s the closest match to dairy in both taste and texture, which is why it has become a café favorite.

Latte Nutrition: Calories, Fat, and Caffeine

If you’re watching what you consume or just curious, it’s good to know the nutritional profile of a latte. Since a latte can be customized a lot (different milk types, added syrups, etc.), we’ll talk about a basic latte first, then how different milks or additions change things. We’ll also cover how much caffeine you’re getting in a latte compared to other drinks.

Calories and Macronutrients in a Latte

A latte’s calories mostly come from the milk (espresso itself has only a few calories per shot). Here’s a general idea for a medium 12 oz latte with whole milk (which might be considered a standard at many coffee shops):

• Calories: ~180 kcal
• Fat: ~7-8 grams (from the milk)
• Carbohydrates (Sugar): ~12-15 grams (mostly the natural lactose sugar in milk; whole milk has ~12g sugar per cup)
• Protein: ~6-8 grams (dairy milk is a good protein source, ~8g per cup)

To give a concrete example, a short 8 oz Starbucks latte made with whole milk has about 115 calories, 6g of fat, 9g of sugar, and 6g of protein. That’s with one shot of espresso (which also contains ~75 mg caffeine). If you increase to a 12 oz (tall) or 16 oz (grande) size with more milk (and perhaps a second shot of espresso), the calories go up accordingly.

A 16 oz latte with 2% milk at Starbucks is around 190 calories, and with whole milk it would be a bit higher (around 210–230 calories). The Healthline nutrition comparison shows a 16-ounce latte has roughly 206 calories, 8g fat, 13g protein, 20g carbs (assuming whole milk).

Now, compare that to a couple of other espresso drinks for context: A 16 oz cappuccino (which has the same espresso but less milk, more foam) was about 130 calories in that comparison. A tiny 2 oz macchiato (just espresso with a dash of milk) is only about 13 calories.

This highlights that lattes have the most milk and thus the most calories among these. As one source put it, “Lattes contain the most milk and are the highest in calories, fat, and protein” compared to cappuccinos or macchiatos.

Milk choice impacts calories: If you make the same 12 oz latte with skim milk instead of whole, you cut down the calories significantly. Skim has roughly half the calories of whole milk. So that ~180 kcal latte could drop to ~120 kcal or less.

Using plant-based milks can also change calories: e.g., an almond milk latte might be only ~100 calories (because almond milk is so low in calories). But an oat milk latte might be similar to a 2% milk latte in calories. Here’s a quick comparison per 8 oz (1 cup) of milk as a reference:

• Whole milk: ~150 calories
• 2% milk: ~120 calories
• Skim milk: ~80 calories
• Oat milk (unsweetened): ~120 calories (varies by brand)
• Soy milk (unsweetened): ~80 calories
• Almond milk (unsweetened): ~40 calories

So, a “skinny latte” (skim milk) can be nearly half the calories of a whole milk latte.

What about sugar? A plain latte has no added sugar, but the milk does contain naturally-occurring sugar (lactose). For example, that 8 oz latte had ~9g sugar from milk. If you add flavored syrup or sweetener, the sugar content will increase.

For instance, a typical flavored latte might have 20–30g of total sugar depending on how many syrup pumps are used. Many coffee chains list their nutrition online, so you can check specifics. For a healthy approach, some people enjoy lattes unsweetened or use sugar-free syrups.

Caffeine Content

A latte’s caffeine comes entirely from the espresso shots, not the milk. The amount of caffeine in your latte depends on how many shots are used.

How Much Caffeine Is in an Espresso Shot?

A standard 1 oz shot of espresso has roughly 60–75 mg of caffeine. This can vary depending on the coffee and preparation method. Some stronger espressos can have up to 85 mg, while milder ones may have closer to 50 mg.

Single-Shot Latte (8–12 oz)

A single-shot latte typically has about 75 mg of caffeine. This is similar to a small cup of brewed coffee. Small or “short” lattes (8 oz) generally use one shot, offering a mild caffeine dose that’s suitable for most people.

Double-Shot Latte (12–16 oz)

A double-shot latte contains around 150 mg of caffeine. This is standard for medium (12 oz) and large (16 oz) lattes at most major chains, including Starbucks.

For example, a 16 oz latte or cappuccino often has two shots, providing roughly 150–170 mg of caffeine. According to Healthline, a typical 16 oz latte has about 173 mg—consistent with two espresso shots.

Larger Sizes and Extra Shots

A hot 20 oz (venti) latte at Starbucks still only includes two shots, equating to about 150 mg of caffeine. However, the iced venti latte includes three shots, boosting the total caffeine to about 225 mg.

Independent cafés may also add a third shot in a 16 oz size, so it’s worth asking if you want to track your intake.

Latte vs. Drip Coffee

For comparison, an 8 oz cup of drip coffee generally contains 95–200 mg of caffeine, depending on the bean and brew strength. So while lattes may seem large, a single-shot latte often has less caffeine than a standard brewed coffee of the same size.

Here’s a quick recap:

• A 12 oz latte (one shot) ≈ 75 mg caffeine.
• A 16 oz latte (two shots) ≈ 150–175 mg caffeine.
• A 2 oz macchiato (just espresso) ≈ 85 mg caffeine (since it’s basically a single shot).
• A 16 oz brewed coffee ≈ 170–200 mg caffeine (varies by coffee strength).

So if you’re sensitive to caffeine, a small latte might actually be a better choice than a big drip coffee, since you’re only getting one shot of espresso. And if you need more kick, you can always request an extra shot in your latte (just know that will add ~75 mg more caffeine).

Bottom line: Lattes generally contain the same amount of caffeine as other espresso drinks of the same number of shots. A cappuccino, flat white, or latte will all have ~75 mg per shot of espresso used. The difference is in volume and milk, not caffeine.

And be mindful of added syrups which don’t affect caffeine but do add sugar. If you want to reduce calories, opt for skim or almond milk and fewer sugary add-ins; if you want to reduce caffeine, you can request just one shot or even decaf espresso. Yes, you can get a decaf latte which has mostly the taste minus most of the caffeine.

(Source note: According to the USDA, a medium 16 oz latte or cappuccino has ~173 mg caffeine with two shots, and a macchiato (~2 oz) has ~85 mg. Also, lattes with more milk are higher in calories while smaller milk drinks are lower.)

Latte vs. Other Espresso Drinks: What’s the Difference?

A latte belongs to the same espresso-and-milk family as cappuccinos, flat whites, macchiatos, and café au lait, but the milk ratio and foam level change the experience. In most cafés, the latte is the smoothest and most milk-forward option in that group.

Latte vs. Cappuccino

A cappuccino usually tastes stronger because there is less milk diluting the espresso and more foam changing the texture. A latte is larger, creamier, and more milk-led, which makes it the gentler choice if you want espresso flavor without the sharper edge.

Comparison Summary

If you want the softest, most milk-forward drink, choose a latte. If you want something bolder, a cappuccino or flat white will usually feel stronger. If you want just a quick espresso hit with minimal milk, a macchiato is closer to that. And if you do not want espresso at all, café au lait is the better comparison point.

How to Make a Latte at Home (Beginner-Friendly)

You do not need a full café setup to make a good latte at home. The essentials are a concentrated coffee base, hot milk, and just enough foam to create a thin cap rather than a thick mound of froth.

Steps to Make a Latte:

1. Pull 1 to 2 shots of espresso, or use a small amount of very strong coffee if you do not have an espresso machine.
2. Heat and froth your milk until it is hot and silky, not dry or overly foamy.
3. Pour the milk into the espresso and finish with a light foam layer on top.

Tips for Beginners:

• Whole milk usually gives the smoothest texture and the most forgiving foam.
• If you are skipping an espresso machine, use a Moka pot, Aeropress, or a very concentrated brew so the coffee still comes through the milk.
• Do not over-froth. If the foam gets stiff and bubbly, the drink starts drifting toward cappuccino territory.
• If you want stronger latte flavor without adding syrup, add an extra espresso shot instead of reducing the milk too drastically.
