December 31, 2025 •

4 min read

Over 50% of the U.S. adult population consumes coffee daily, and a growing number are seeking plant-based options, which is why knowing which alternative milk is best for lattes is more important than ever. With so many non-dairy milks now available, finding the right one to pair with your espresso can make or break your morning ritual.

Quick Summary

This guide evaluates popular non-dairy milks—including oat, soy, almond, and pea—based on their performance in lattes. It examines factors like taste, frothing quality, and overall texture to help you choose the best milk alternative for a delicious, creamy beverage.

Key Points

Oat Milk is a top choice: Praised by baristas for its creamy texture, mild flavor, and excellent frothing ability, especially Barista Editions.
Soy Milk is a reliable option: It has a high protein content for a thick foam, but requires careful temperature control to avoid curdling with acidic espresso.
Almond Milk can be inconsistent: Standard versions may be watery with unstable foam, but 'Barista Blends' with added stabilizers improve performance significantly.
Pea Milk is a neutral newcomer: This high-protein milk creates a stable, creamy foam without a strong flavor, making it a great neutral-tasting choice.
Coconut Milk adds a strong flavor: Provides a rich mouthfeel from its fat content but has a strong tropical taste that can overwhelm delicate coffee flavors.
Rice Milk is not recommended: Its low protein and fat content prevent it from creating a good foam, resulting in a thin, watery latte.
Choose 'Barista' blends: These versions are formulated to steam and foam better than standard alternative milks and are worth the investment for a superior latte.
Proper temperature is key: Overheating any alternative milk can cause it to separate or curdle, so aim for a temperature between 55–65°C (130–150°F).

Understanding the Science of Steaming

Making the perfect latte isn't just about the espresso; it's about the milk. When steaming milk, the goal is to create a velvety microfoam, a fine, dense foam without large bubbles, which is essential for texture and latte art. This process is influenced by a milk's fat, protein, and sugar content.

Proteins are crucial for creating the stable structure of the foam. As milk is heated, the protein molecules denature (unfold) and surround tiny air bubbles, forming a stable network. Fat provides the rich, creamy mouthfeel and helps to stabilize the foam, preventing it from dissipating too quickly. The natural sugars caramelize slightly when heated, adding a pleasant sweetness that complements the coffee.

A Deep Dive into the Top Contenders

Oat Milk: The Barista's Favorite

Oat milk has emerged as the top contender for lattes, and for good reason. Its naturally high fat and sugar content create a creamy, silky microfoam that is very similar to dairy milk. The flavor is mild and slightly sweet, allowing the coffee's notes to shine through rather than overpowering them. Barista-specific oat milks, like Oatly Barista Edition, are specially formulated with added stabilizers to ensure consistent and excellent performance when steamed.

Soy Milk: The Original Alternative

One of the longest-standing alternative milks, soy milk can produce a thick, creamy foam due to its high protein content. However, it can sometimes curdle when exposed to the high acidity and temperature of espresso. To prevent this, baristas recommend steaming soy milk gently and at a lower temperature, around 55°C, and adding the espresso slowly. The flavor is often more pronounced and nutty than oat milk, which can either complement or compete with the coffee's flavor depending on personal preference.

Almond Milk: A Lighter, Nutty Option

Almond milk is a popular, lower-calorie choice, but its performance in lattes can be inconsistent. Standard almond milk has low protein and fat content, making it difficult to produce a stable, thick foam. The resulting texture can often be thin and watery, with large, quick-to-dissipate bubbles. Barista blends, like Califia Farms Almondmilk Barista Blend, are a better option as they contain stabilizers that improve frothing. The nutty flavor adds a distinct note to the latte, which works well with certain coffee roasts.

Pea Milk: The Promising Newcomer

Pea milk, made from yellow peas, is a new addition to the market and shows great promise for lattes. It is rich in protein, which helps it create a stable, creamy foam similar to oat milk. The taste is relatively neutral, so it doesn't interfere with the coffee's flavor profile. Availability may still be inconsistent, but brands like Ripple Barista Style have gained a following for their excellent performance.

Coconut Milk: A Tropical Twist

For those who love a tropical, rich flavor, coconut milk is a viable option. Its higher fat content helps it to froth, but the intense coconut flavor can significantly alter the taste of the espresso. The foam can be less stable than oat or soy milk and has a more diluted mouthfeel. It is best for those who specifically enjoy the coconut flavor profile in their coffee.

Rice Milk: The Least Recommended

Due to its high water content and very low protein and fat, rice milk is generally not recommended for lattes. It froths poorly and results in a watery, thin texture that lacks the creamy body essential for a good latte.

The Verdict: A Quick Comparison

This table provides a side-by-side comparison of the most common alternative milks for lattes.


Milk Alternative	Best For	Frothing Ability	Flavor Profile	Notes
Oat Milk	All-around performance, latte art	Excellent (especially Barista blends)	Mild, creamy, slightly sweet	Most café-like experience
Soy Milk	High-protein option	Good (can curdle if overheated)	Pronounced, nutty	Requires careful steaming
Almond Milk	Low-calorie, nutty flavor	Varies (Barista blends perform better)	Nutty, sometimes watery	Watch out for separation
Pea Milk	Neutral flavor, good foam	Very good	Neutral, creamy	A promising, protein-rich option
Coconut Milk	Tropical flavor	Moderate	Strong, distinct coconut	Can overpower delicate coffee flavors
Rice Milk	Not recommended	Poor	Very thin, watery	Lacks body and foam quality

How to Get the Best Results at Home

Regardless of which alternative milk you choose, follow these tips to maximize your latte quality:

Choose a Barista Blend: These are specifically formulated to froth better and resist curdling.
Use Fresh, Cold Milk: Freshly opened, cold cartons of milk produce the best foam.
Don't Overheat: Aim for a temperature between 55–65°C (130–150°F). Overheating can cause milk to burn or curdle.
Practice Your Technique: Steaming requires patience. Incorporate air briefly at the beginning and then submerge the wand to create a vortex that polishes the milk to a fine microfoam.

Conclusion: Your Perfect Latte Awaits

Ultimately, the best alternative milk for your latte depends on your personal taste and priorities. For those who want the most reliable and café-like experience, oat milk, especially a barista edition, is the clear winner for its superior texture and neutral flavor. Soy milk remains a solid, protein-rich choice, but requires more care during steaming. For a lighter, nutty taste, a barista blend almond milk can be excellent, while pea milk is a great, neutral-tasting contender. Experimentation is key to finding your personal favorite. The right alternative milk can transform your latte, proving that great coffee doesn't always need dairy.

What to Look for in a Barista Blend

When searching for an alternative milk for lattes, specifically look for cartons labeled 'Barista' or 'Professional.' These versions are designed to withstand heat and create stable foam, thanks to added ingredients like oils or stabilizers. This ensures your latte will be creamy and smooth, not separated or watery.
