As plant-based lifestyles become more mainstream, dairy-free coffee lovers have more options than ever when it comes to milk alternatives. But when it’s time to pair that creamy addition with your morning brew, two non-dairy contenders dominate the conversation: oat milk and almond milk.
Both are popular, widely available, and come with distinct flavors, textures, and nutritional profiles. But when it comes to making the perfect dairy-free latte, cappuccino, or iced coffee, which one wins?
Let’s explore the differences between oat milk and almond milk—how they perform in coffee, how they taste, and which is the better choice depending on your needs in 2025.
The Rise of Dairy-Free Coffee Culture
Non-dairy milk isn’t just a health trend anymore—it’s a lifestyle choice driven by environmental concerns, lactose intolerance, vegan diets, and even flavor preferences. Coffee shops around the world now offer oat, almond, soy, coconut, and even macadamia milk.
Among these, oat milk and almond milk remain the top choices due to their neutral flavor profiles and versatility. Whether you’re steaming for a cappuccino or mixing into cold brew, these two are the most common go-to plant milks behind the bar.
Oat Milk in Coffee: Creamy and Smooth
Taste and Texture
Oat milk has a naturally sweet, mellow flavor that complements coffee exceptionally well. Its texture is creamy and full-bodied, almost mimicking whole dairy milk. This richness allows oat milk to blend seamlessly into both hot and iced drinks without overpowering the coffee.
Baristas love oat milk for its ability to foam beautifully, creating stable microfoam for lattes and cappuccinos. In fact, many coffee shops now use “barista blend” oat milk, designed specifically for espresso-based drinks.
Nutritional Highlights
Oat milk tends to be higher in carbohydrates and natural sugars than almond milk, which contributes to its sweetness and creamy mouthfeel. It usually contains added vitamins like B12, D, and calcium, especially in fortified versions.
Some oat milks have added oils (such as rapeseed or sunflower oil) to improve texture, so be sure to check the label if you’re avoiding processed oils.
Environmental Impact
Oat milk has a relatively low environmental footprint. Oats are easy to grow, require less water than nuts, and produce fewer greenhouse gases compared to dairy or almond farming.
Best For: Lattes, cappuccinos, iced coffee, people looking for a creamy, dairy-like texture.
Almond Milk in Coffee: Light and Nutty
Taste and Texture
Almond milk has a nutty, slightly bitter flavor that doesn’t always mesh with every coffee roast. It’s naturally thinner than oat milk, which makes it better for black coffee drinkers who want a lighter splash rather than full-on creaminess.
In steamed drinks, almond milk can sometimes curdle or separate when mixed with acidic coffee, especially in high-heat environments. However, barista-formula almond milks are now designed to resist separation and offer smoother performance.
Nutritional Highlights
Almond milk is lower in calories and carbs than oat milk, making it a popular choice for keto, low-carb, or calorie-conscious consumers. It’s often fortified with vitamin E, calcium, and D, and is typically free from added sugars unless flavored.
If you’re watching blood sugar or counting macros, almond milk may be the better option.
Environmental Impact
Almond milk has come under scrutiny in recent years for its high water consumption, especially in regions like California where almonds are heavily farmed. However, it still uses significantly less water than dairy milk and has a smaller carbon footprint overall.
Best For: Light coffee drinks, cold brew, calorie-conscious drinkers, nut milk fans.

Barista Tips for Using Oat and Almond Milk
Use Barista Blends
Barista editions are formulated with added stabilizers and fats to enhance performance under heat and pressure. These blends create better foam, structure, and taste in hot drinks.
Watch the Temperature
When steaming almond milk, avoid overheating above 130°F to reduce curdling. Oat milk is more forgiving and can handle temperatures up to 150–155°F.
Pair with the Right Roast
- Oat milk pairs beautifully with medium to dark roasts, enhancing the richness and body.
- Almond milk does better with light to medium roasts, where the nuttiness can add dimension.
Shake Before Use
Both oat and almond milk tend to settle in the carton. Always give your plant milk a good shake before pouring for consistency and foam quality.
Which One Is Better for Coffee?
There’s no one-size-fits-all answer—it depends on what you want from your cup.

- Want a creamy, dairy-like experience
- Enjoy espresso drinks like lattes and flat whites

- Are looking for eco-friendly and nut-free options
