As the world shifts towards a more plant-based diet, oat milk has become a popular dairy-free alternative for coffee lovers. However, one common concern that arises is whether Oatly, a well-known oat milk brand, curdles in coffee. In this article, we will delve into the science behind oat milk and coffee, exploring the reasons why Oatly might curdle and providing tips on how to prevent it.
What is Oatly and How is it Made?
Before we dive into the world of oat milk and coffee, let’s first understand what Oatly is and how it’s made. Oatly is a Swedish company that produces oat milk, a plant-based milk alternative made from oats and water. The production process involves soaking oats in water, blending them with water, and then straining the mixture to create a creamy liquid.
The resulting oat milk is rich in fiber, vitamins, and minerals, making it a popular choice for those looking for a dairy-free alternative. Oatly offers a range of products, including barista edition oat milk, which is specifically designed for use in coffee.
The Science Behind Oat Milk and Coffee
So, why does Oatly curdle in coffee? To understand this, we need to look at the science behind oat milk and coffee. Oat milk is a complex mixture of carbohydrates, proteins, and fats, which can interact with the acidity and heat of coffee in different ways.
The Role of Acidity in Coffee
Coffee is a acidic beverage, with a pH level of around 5.5. This acidity can cause the casein in milk to coagulate, resulting in curdling. However, oat milk doesn’t contain casein, so why does it still curdle?
The answer lies in the type of carbohydrates present in oat milk. Oats contain a type of carbohydrate called beta-glucans, which can interact with the acidity in coffee. When oat milk is added to coffee, the beta-glucans can break down and form a gel-like substance, causing the milk to curdle.
The Role of Heat in Coffee
Heat is another factor that can contribute to curdling in oat milk. When oat milk is heated, the proteins and carbohydrates can denature and aggregate, leading to a change in texture and consistency. This can cause the milk to curdle or separate when added to coffee.
The Role of Fat Content in Oat Milk
The fat content in oat milk can also play a role in curdling. Oat milk contains a small amount of fat, which can separate from the rest of the liquid when heated or exposed to acidity. This can cause the milk to curdle or form a layer of fat on top of the coffee.
Why Does Oatly Curdle in Coffee?
Now that we’ve explored the science behind oat milk and coffee, let’s look at why Oatly might curdle in coffee. There are several reasons why this might happen:
- High acidity in coffee: If the coffee is too acidic, it can cause the beta-glucans in Oatly to break down and form a gel-like substance, leading to curdling.
- Incorrect temperature: If the coffee is too hot, it can cause the proteins and carbohydrates in Oatly to denature and aggregate, leading to curdling.
- Insufficient mixing: If the Oatly is not mixed properly with the coffee, it can cause the milk to separate and curdle.
- Old or low-quality Oatly: If the Oatly is old or of poor quality, it can be more prone to curdling.
How to Prevent Oatly from Curdling in Coffee
While curdling can be a problem when using Oatly in coffee, there are several ways to prevent it:
- Use a lower acidity coffee: If you’re finding that your coffee is too acidic, try switching to a lower acidity coffee bean.
- Heat the Oatly separately: Instead of adding the Oatly directly to the coffee, try heating it separately and then adding it to the coffee. This can help to prevent the proteins and carbohydrates from denaturing and aggregating.
- Use a milk frother or steam wand: If you’re using a coffee machine with a milk frother or steam wand, try using it to froth the Oatly before adding it to the coffee. This can help to create a creamy texture and prevent curdling.
- Experiment with ratios: If you’re finding that the Oatly is curdling, try experimenting with different ratios of Oatly to coffee. You may find that using a higher ratio of coffee to Oatly helps to prevent curdling.
Conclusion
In conclusion, Oatly can curdle in coffee due to a combination of factors, including acidity, heat, and fat content. However, by understanding the science behind oat milk and coffee, we can take steps to prevent curdling and create a delicious and creamy coffee drink.
Whether you’re a coffee aficionado or just starting to explore the world of plant-based milk alternatives, we hope this article has provided you with valuable insights and tips on how to use Oatly in coffee. So go ahead, experiment with different ratios and techniques, and find your perfect cup of coffee with Oatly.
Additional Tips for Using Oatly in Coffee
- Try different flavors: Oatly comes in a range of flavors, including barista edition, original, and flavored varieties. Experiment with different flavors to find the one that works best for you.
- Use Oatly in cold brew coffee: If you’re finding that Oatly is curdling in hot coffee, try using it in cold brew coffee instead. The lower acidity and temperature of cold brew coffee can help to prevent curdling.

What is Oatly and how does it compare to other plant-based milks?
Oatly is a popular plant-based milk alternative made from oats and water. It is known for its creamy texture and neutral flavor, making it a great option for those looking for a dairy-free milk substitute. Compared to other plant-based milks, Oatly has a higher viscosity and a more velvety texture, which makes it a great addition to coffee and other beverages.
One of the main advantages of Oatly is its sustainability. Oats require less water to produce than almonds, which are commonly used to make almond milk. Additionally, oats are a more environmentally friendly crop than many other plant-based milk alternatives. This makes Oatly a great option for those looking for a sustainable and eco-friendly milk alternative.
Why does Oatly sometimes curdle in coffee?
Oatly can curdle in coffee due to the acidity and heat of the coffee. When Oatly is added to hot coffee, the acidity of the coffee can cause the oats to coagulate and separate, resulting in a curdled texture. This is more likely to happen when using a darker roast coffee or when adding Oatly to coffee that is too hot.
Another reason Oatly may curdle in coffee is due to the type of oats used to make the milk. Some types of oats are more prone to curdling than others. Oatly uses a specific type of oat that is designed to be more stable in hot beverages, but it can still curdle in certain conditions.
How can I prevent Oatly from curdling in my coffee?
To prevent Oatly from curdling in your coffee, try adding it to the coffee when it’s not too hot. This will help prevent the oats from coagulating and separating. You can also try adding a small amount of Oatly to the coffee and stirring it in slowly, which can help distribute the oats evenly and prevent curdling.
Another tip is to use a lighter roast coffee, which tends to be less acidic than darker roasts. You can also try adding a pinch of salt to the coffee, which can help stabilize the oats and prevent curdling. Experimenting with different ratios of Oatly to coffee can also help you find the perfect balance to prevent curdling.
What is the science behind Oatly curdling in coffee?
The science behind Oatly curdling in coffee is related to the properties of the oats and the acidity of the coffee. Oats contain a type of carbohydrate called beta-glucans, which can absorb liquid and swell. When Oatly is added to hot coffee, the acidity of the coffee can cause the beta-glucans to coagulate and separate, resulting in a curdled texture.
The acidity of the coffee also plays a role in the curdling process. Coffee has a pH level of around 5, which is acidic enough to cause the oats to coagulate. When the oats coagulate, they can separate from the liquid and form a curdled texture. Understanding the science behind Oatly curdling in coffee can help you take steps to prevent it and enjoy a smooth and creamy coffee.
Can I use Oatly in cold brew coffee?
Yes, you can use Oatly in cold brew coffee. In fact, Oatly is a great addition to cold brew coffee because it can add a rich and creamy texture without curdling. Since cold brew coffee is not hot, the acidity of the coffee is less likely to cause the oats to coagulate and separate.
Using Oatly in cold brew coffee can also help to bring out the flavors of the coffee. The creamy texture of Oatly can complement the smooth and low-acidity flavor of cold brew coffee, making it a great combination for those looking for a dairy-free coffee drink. Simply add Oatly to your cold brew coffee and stir it in slowly to distribute the oats evenly.
Are there any other plant-based milks that are less likely to curdle in coffee?
Yes, there are other plant-based milks that are less likely to curdle in coffee. For example, soy milk and coconut milk are less prone to curdling than Oatly. This is because they have a different composition and are less affected by the acidity of the coffee.
However, it’s worth noting that these milks may not have the same creamy texture as Oatly, which can be a drawback for some coffee drinkers. Additionally, some plant-based milks may have a stronger flavor than Oatly, which can affect the taste of the coffee. Experimenting with different plant-based milks can help you find the one that works best for you.
