What Causes Oat Milk to Curdle?

When oat milk becomes too heated or too acidic, it curdles.

Oat milk is made from oats that have been combined with water, filtered, and emulsified for a smoother texture. However, when exposed to acid or becomes too heated, this non-dairy milk can break down and curdle. This separation can sometimes be repaired by further emulsifying (shaking, blending, or using an actual emulsifier).

Is Curdled Oat Milk Harmful?

Curdled oat milk can be harmful, however it is not always.

For example, if your oat milk is curdling or separating, it could be that it is going to expire. If you’ve left your oat milk coffee creamer out for too long, or if it’s over its expiration date, you may need to replace it with fresher oat milk.

Curdled oat milk, on the other hand, isn’t always a bad thing in many cases. If you’re looking for visual appeal, your coffee or whatever you’re putting your oat milk in may appear unappealing, but the flavour will be the same.

The answer to whether or not curdled oat milk will hurt you is simple. Curdled oat milk will not hurt you unless the cause of the curdled oat milk is a lack of freshness.

Is It Safe to Drink Curdled Oat Milk?

Drinking curdled oat milk is entirely safe assuming your oat milk is fresh.

Regardless, the sight of curdled milk is enough to make many people lose their appetite. This is due to the fact that curdled milk is commonly linked with rotting. However, curdled oat milk can arise for a variety of causes in this case. The majority of the causes have nothing to do with spoilage and instead have to do with the pH or temperature of the drink.

Should Oat Milk Contain Bits?

Oat milk can certainly contain particles.

Don’t be frightened if you discover what appear to be little white particles in your oat milk. These specks are occasionally not entirely mixed out and float in suspension in oat milk. You may be able to shake the carton occasionally to assist the specks disappear.

If shaking does not work, the oat milk should still taste good and have a consistent consistency. If it doesn’t, the oat milk was probably not fresh to begin with.

Should there be chunks in oat milk?

Oat milk may have lumps. These will be larger than the unblended white flecks stated above. You should not be concerned if you notice these.

Remember that oat milk is prepared by blending oats and water until creamy before filtering. Little pieces, flakes, or “chunks” can sometimes be overlooked. This is a common occurrence and does not indicate that there is anything wrong with your oat milk.

Separation of Oat Milk in Coffee

Some individuals remark that oat milk separates in their coffee. Some people are completely unaware of this.

The discrepancy is most likely due to the brand of oat milk utilised. Many companies use various chemicals and emulsifying procedures. Some oat milk types are even engineered to handle higher heat temperatures and acidity. This makes them more appropriate for use in coffee shops. Oatly, Arpo, and other “barista” oriented brands are excellent examples of such oat milks.

Does Oat Milk Curdle When…

Is it possible for oat milk to curdle in coffee?

Oat milk does not always curdle in coffee, but it can. If you find your oat milk curdling while creating a cappuccino or iced coffee, it is most likely due to a chemical reaction between your oat milk and coffee. The oat milk may curdle due to the greater amounts of acidity and maybe the heat of the coffee. This is especially true if you have hot coffee and cold oat milk.

To avoid this, consider warming your oat milk and slowly adding hot coffee to your already poured oat milk. This will help to temper the oat milk so that it does not respond badly to the temperature differential.

If your oat milk continues to curdle after this, consider a darker coffee roast, as medium and lighter roasts may contain more acid. Cold brews have less acid.

Does expired oat milk curdle in coffee?

When oat milk is exposed to coffee, it is more likely to separate or curdle if it is expired or close to expiration. As a result, it is preferable to use fresh oat milk, especially if you are concerned about the appearance of your coffee.

Of course, to determine whether your oat milk is fresh, check the expiration date on the package and take note of any changes in colour, smell, or consistency.

If you make your own oat milk, it will usually last around five days.

While many people use oat milk as a nondairy substitute for milk in coffee, it has numerous other applications. Check out the commonly asked questions about oat milk curdling to learn more about how oat milk compares to other liquids and beverages.

Is it possible for oat milk to curdle in tea?

Tea with oat milk may curdle. However, it is crucial to note that most teas are not as acidic as coffee, and that the pH of each tea varies. As a result, while oat milk curdling is less likely in tea than it is in acidic coffee, it can still occur.

Not only that, but the warmth of your tea can influence whether or not your oat milk separates. Warm your milk first before adding it to your tea to reduce the possibility of curdling and separation.

Does Lemon Curdle Oat Milk?

Because lemon has a pH of roughly 2 (thus the sour taste), you can sure your oat milk will curdle when paired with lemon. When more acidic fruits, such as strawberries, are added, you may witness curdling or separation.

Keep in mind that if you use your oat milk to cook or bake, it may not matter if it separates and curdles. To make dairy-free buttermilk, many people add lemon juice to plant-based drinks. Others like to soak strawberries in oat milk before making lactose-free strawberry oatmeal. In any case, the curdling and separation will be insignificant once the liquid has been boiled and distributed throughout the dish.
