What Kind of Milk Is in a Skinny Latte?

December 4, 2025 •

3 min read

By default, a skinny latte is prepared using skim milk, which dramatically reduces the fat and calorie content compared to a regular latte. This choice of milk is the defining characteristic that separates a "skinny" version from its whole milk counterpart, appealing to health-conscious coffee drinkers.

Quick Summary

A skinny latte uses low-fat milk, typically nonfat or skim, to reduce its calorie and fat content. Numerous dairy and plant-based alternatives are available to customize the drink to your preference, including almond, oat, and soy milk, each offering a different flavor and nutritional profile.

Key Points

Default Milk: A skinny latte is traditionally made with nonfat (skim) milk to reduce its calorie and fat content.
Flavor Profile: With less fat to balance the espresso, a skinny latte has a more prominent coffee flavor than a regular latte.
Dairy-Free Options: Popular non-dairy alternatives for a skinny latte include almond, oat, and soy milk, which offer unique flavors and textures.
Foam Texture: The low-fat content of skim milk produces a lighter, airier foam compared to the dense, velvety foam from whole milk.
Calorie Savings: Swapping whole milk for skim milk can save a significant number of calories, with an 8oz skinny latte containing around 90 calories versus 150+ for a standard latte.
Customizations: Sugar-free syrups, natural sweeteners like stevia, or spices like cinnamon can be added for flavor without adding calories.

The Defining Milk in a Skinny Latte

When you order a skinny latte, you are signaling to your barista that you prefer a lower-calorie, lower-fat version of the classic caffe latte. The fundamental difference lies in the milk choice. While a traditional latte is made with whole milk, the 'skinny' iteration uses nonfat, or skim, milk. This substitution significantly impacts the beverage's nutritional profile without sacrificing the smooth, rich espresso base.

How Skim Milk Affects the Latte

Skim milk, with its minimal fat content, produces a different foam texture than whole milk. While whole milk creates a dense, velvety microfoam, skim milk produces a lighter, airier foam. The flavor profile is also affected; with less fat to temper the coffee's intensity, the espresso's robust flavor notes are more prominent in a skinny latte. This can be a benefit for those who enjoy the strong taste of coffee but still want the comforting warmth of a milk-based drink.

Dairy Alternatives for Your Skinny Latte

For those with dietary restrictions or specific health goals, the skinny latte can be customized with various dairy-free milks. These options provide unique flavors and different nutritional benefits.

Almond Milk: A popular choice for a nutty flavor and significantly fewer calories than dairy milk. Almond milk generally froths well, though quality can vary by brand.
Oat Milk: Known for its natural sweetness and creamy consistency, oat milk produces a rich, stable foam, making it a favorite among many baristas.
Soy Milk: A high-protein, plant-based option that creates a consistent, creamy microfoam, mimicking the texture of dairy milk quite well.
Coconut Milk: Offers a low-carb alternative with a distinct, subtle coconut flavor. Some variations can be high in fat, so checking the label is essential.

Customizing Your Skinny Latte

Beyond the milk, several other modifications can make your skinny latte even healthier. Many coffee shops offer sugar-free syrups to add flavor without extra calories. A skinny vanilla latte, for example, typically uses a sugar-free vanilla syrup along with nonfat milk. Natural sweeteners like stevia can also be used. For those who prefer no added sweeteners, a simple sprinkle of cinnamon or nutmeg can add a touch of flavor without impacting the calorie count.

Comparison: Skinny Latte vs. Standard Latte

Fat Content	Higher (significantly more saturated fat)	Lower (minimal fat)
Taste Profile	Creamy, smooth, and mellow; the milk balances the espresso's intensity	Lighter, less creamy; the espresso's flavors are more prominent
Foam Texture	Rich, dense, and velvety microfoam	Lighter and airier foam that dissolves faster
