Oat Beverage vs Oat Milk: What’s the Difference?

Oat beverage and oat milk are often used interchangeably, but oat beverage may refer to a broader range of oat-based drinks, including flavored options.

The plant-based milk aisle can be confusing with terms like “oat beverage” and “oat milk” appearing on similar products. While these terms are often used interchangeably, there are some subtle differences worth understanding before making your next purchase.

The Core Similarities

Both oat beverage and oat milk are made through the same basic process:

• Oats are soaked in water
• The mixture is blended into a creamy liquid
• The pulp is strained out
• Additional ingredients may be added for flavor or nutrition

Both options are naturally:

• Dairy-free
• Lactose-free
• Vegan
• Lower in environmental impact than dairy milk

Key Differences Explained

1. Terminology and Labeling

The term “oat beverage” is often used because:

• Some countries regulate the use of “milk” for non-dairy products
• It helps avoid confusion for those with dairy allergies
• Some brands prefer this more technical description

Meanwhile, “oat milk” remains the more common consumer-friendly term that describes the product’s creamy, milk-like qualities.

2. Texture and Consistency

Generally:

• Oat milk tends to be thicker and creamier
• Oat beverage is often slightly thinner

This difference comes from:

• Higher oat content in oat milk
• Different straining processes
• Variations in added stabilizers or emulsifiers

3. Nutritional Profile

Nutrient	Oat Milk	Oat Beverage
Protein	Higher (2-4g per serving)	Lower (1-2g per serving)
Fiber	More	Less
Fortification	Common	Sometimes

Many brands fortify both products with calcium, vitamin D, and B12 to match dairy milk’s nutritional benefits. Always check labels as formulations vary.

Which One Should You Choose?

Best Uses for Oat Milk

The creamier texture makes oat milk ideal for:

• Coffee creamer
• Baking (try it in milkshakes)
• Creamy soups and sauces
• Desserts

Best Uses for Oat Beverage

The lighter consistency works well for:

• Pouring over cereal
• Adding to tea
• Light smoothies
• Drinking straight

Environmental and Health Considerations

Both options are more sustainable than dairy milk, requiring:

• 80% less land
• 60% less energy
• 75% fewer greenhouse gas emissions

According to BBC Good Food, oat milk has one of the lowest environmental impacts among plant milks.

Making Your Own at Home

You can easily make either version with:

1. 1 cup rolled oats
2. 4 cups water
3. Pinch of salt
4. Optional: sweetener, vanilla

For creamier “oat milk”:

• Use less water (3 cups)
• Add 1 tbsp oil
• Strain through cheesecloth

For lighter “oat beverage”:

• Use more water (5 cups)
• Strain through fine mesh

Store homemade versions in the fridge for 3-4 days. Shake well before use as separation is natural.

Shopping Tips

When choosing between commercial products:

• Check protein content if that’s important to you
• Look for unsweetened versions to avoid added sugars
• Consider fortification if replacing dairy milk
• Read reviews about texture and performance in coffee

For those who enjoy experimenting, a good blender can help you create custom versions at home.

As noted by Healthline, commercial oat milks often contain added vitamins and minerals that homemade versions lack.

Final Thoughts

While the terms “oat beverage” and “oat milk” describe very similar products, understanding these subtle differences can help you make the best choice for your needs. Whether you prefer the creamier texture of oat milk or the lighter consistency of oat beverage, both offer delicious, sustainable alternatives to dairy milk.
