As the world shifts towards a more plant-based lifestyle, oat milk has become a staple in many coffee lovers’ daily routines. However, a common concern has been plaguing oat milk enthusiasts: does oat milk curdle in coffee? In this article, we’ll delve into the world of oat milk and coffee, exploring the science behind curdling, the reasons why it happens, and most importantly, how to prevent it.
Understanding Oat Milk and Its Properties
Before we dive into the curdling conundrum, it’s essential to understand the properties of oat milk. Oat milk is a plant-based milk alternative made by soaking oats in water and blending them with water. The resulting liquid is then strained to create a creamy, milk-like texture. Oat milk is naturally free from lactose, making it an excellent option for those with dairy intolerance or preferences.
One of the key characteristics of oat milk is its pH level. Oat milk has a slightly acidic pH, ranging from 6.5 to 7.5. This acidity plays a crucial role in its interaction with coffee, as we’ll explore later.
The Science of Curdling
Curdling occurs when the proteins in milk (or in this case, oat milk) coagulate and separate from the liquid. This can happen due to various factors, including changes in temperature, pH, or the presence of certain enzymes. When oat milk is added to coffee, the acidity of the coffee can cause the proteins in the oat milk to coagulate, resulting in an unappealing, curdled texture.
However, it’s not just the acidity of the coffee that contributes to curdling. The type of coffee, brewing method, and even the ratio of coffee to oat milk can all impact the likelihood of curdling.
Why Does Oat Milk Curdle in Coffee?
So, why does oat milk curdle in coffee? There are several reasons:
Acidity of Coffee
As mentioned earlier, the acidity of coffee plays a significant role in curdling. Coffee has a pH level of around 5.5, which is more acidic than oat milk. When oat milk is added to coffee, the acidity of the coffee can cause the proteins in the oat milk to coagulate, leading to curdling.
Temperature of Coffee
The temperature of the coffee can also contribute to curdling. If the coffee is too hot, it can cause the proteins in the oat milk to denature and coagulate, resulting in a curdled texture.
Ratio of Coffee to Oat Milk
The ratio of coffee to oat milk can also impact the likelihood of curdling. If the ratio of coffee to oat milk is too high, the acidity of the coffee can overpower the oat milk, causing it to curdle.
Type of Coffee
The type of coffee can also play a role in curdling. Espresso, for example, has a higher acidity level than drip coffee, making it more likely to cause curdling.
How to Prevent Oat Milk from Curdling in Coffee
While curdling can be a frustrating issue, there are several ways to prevent it:
Choose a Barista-Style Oat Milk
Barista-style oat milk is specifically designed for use in coffee. It has a higher fat content and a more stable pH level, making it less likely to curdle.
Use a Lower Ratio of Coffee to Oat Milk
Using a lower ratio of coffee to oat milk can help prevent curdling. Start with a small amount of coffee and gradually add more to taste.
Heat the Oat Milk Separately
Heating the oat milk separately before adding it to the coffee can help prevent curdling. This allows the oat milk to heat up gradually, reducing the likelihood of protein coagulation.
Use a Coffee with a Lower Acidity Level
Using a coffee with a lower acidity level can help prevent curdling. Look for coffee beans that have been roasted to a darker level, as these tend to have a lower acidity level.
Add Oat Milk to Coffee in a Specific Order
Adding oat milk to coffee in a specific order can also help prevent curdling. Try adding the oat milk to the coffee in a circular motion, starting from the center of the cup and working your way outwards. This helps to distribute the oat milk evenly and reduces the likelihood of curdling.
Conclusion
In conclusion, oat milk can curdle in coffee due to various factors, including acidity, temperature, and ratio of coffee to oat milk. However, by choosing a barista-style oat milk, using a lower ratio of coffee to oat milk, heating the oat milk separately, using a coffee with a lower acidity level, and adding oat milk to coffee in a specific order, you can reduce the likelihood of curdling and enjoy a smooth, creamy cup of coffee.
As the demand for plant-based milk alternatives continues to grow, it’s essential to understand the properties and behaviors of these alternatives. By exploring the science behind curdling and implementing simple prevention methods, you can enjoy a delicious and satisfying cup of coffee with oat milk.

What is oat milk and how is it made?
Oat milk is a plant-based milk alternative made from oats and water. It is created by soaking oats in water, blending them with additional water, and then straining the mixture to remove the solids. The resulting liquid is oat milk, which can be flavored, sweetened, and fortified with various nutrients.
The production process of oat milk can vary depending on the manufacturer, but most commercial brands use a similar process. Some brands may add additional ingredients, such as gums or emulsifiers, to improve the texture and shelf life of the milk. However, many consumers prefer to make their own oat milk at home, as it allows them to control the ingredients and the level of sweetness.
Why does oat milk curdle in coffee?
Oat milk can curdle in coffee due to the acidity and heat of the coffee. When oat milk is added to hot coffee, the casein proteins in the milk can coagulate and separate from the liquid, causing it to curdle. This is more likely to happen if the coffee is very hot or if the oat milk is not of high quality.
However, it’s worth noting that not all oat milk will curdle in coffee. Some brands have developed special formulas that are designed to be more stable in hot beverages. Additionally, baristas and coffee enthusiasts have developed various techniques for preventing curdling, such as heating the oat milk separately before adding it to the coffee or using a steam wand to froth the milk.
Is curdling a problem with all plant-based milks?
No, curdling is not a problem with all plant-based milks. While oat milk is particularly prone to curdling, other plant-based milks such as almond milk, soy milk, and coconut milk are less likely to curdle in coffee. This is because these milks have a different protein structure and are often more stable in hot beverages.
However, it’s worth noting that some plant-based milks can still separate or become watery when added to coffee. This can be due to the natural oils and proteins in the milk, which can separate from the liquid when exposed to heat. But in general, curdling is a more specific issue with oat milk.
Can I prevent oat milk from curdling in coffee?
Yes, there are several ways to prevent oat milk from curdling in coffee. One method is to heat the oat milk separately before adding it to the coffee.
