One fine day, I purchased Half and Half Coffee Creamer to enhance the taste and flavor of my daily coffee.

But when I added it to my cup of hot brewed coffee, it started to curdle in the coffee.

At that time, I wondered why it happened and the first thought that came to my mind is that will it be ok to drink a coffee with curdled cream in it.

Therefore, I researched about this topic a lot and this is what I found after hours of research.

The simple and short answer to the question “why does cream curdle in coffee?” is the higher acidity of your coffee and increased lactic acid content of your coffee creamer.

These are the two major factors which decides whether the coffee creamer curdles in your coffee or not.

The higher temperature of your coffee becomes an important factor too. The lactic acid of your coffee creamer becomes stronger when the creamer freshness decreases over a period.

If you use a creamer that is not very fresh, then its lactic acid content increases. When the ratio of lactic acid and the acid in your coffee is very high, it disturbs the pH balance of your coffee creamer.

This is why, expired or not so fresh coffee creamer and too much acidity in your coffee are the two main contributing factors that leads to cream curdling in your daily coffee.

Now, you know the true reason behind this curdling phenomenon, I want to provide few more interesting facts regarding cream curdling in your coffee.

I recommend you to read this article till the end so that you know whether its safe to drink such coffee and then I will show you 3 easy methods to prevent this cream curdling phenomenon.

Is It OK to Drink Curdled Cream in Coffee?

If you are fearful of drinking such coffee with cream curdling in it, then I want to assure you that its completely harmless and safe for your health.

There is no big issue in drinking such coffee unless and until the used coffee creamer is past its expiration date.

If you don’t believe me then I would like you to read this FAQ of Nestle.ca.

The Nestle company has clearly mentioned that drinking such coffee with cream curdling in it, is completely harmless and safe for us.

They mention this concept as “Beverage Feathering”.

They call it as a harmless physical reaction which does not indicate that the quality of your creamer is bad or it has expired.

Therefore, my opinion on this issue is you will need to make sure that the coffee creamer you use must not be expired or past its expiration date.

Plus, if you choose healthy coffee creamer for your coffee which is fresh and made from quality ingredients, then you will have less chances of cream curdling.

I highly recommend you to buy only healthy coffee creamers which are not expired and made from non-dairy and plant based ingredients.

What Happens if You Drink Curdled Cream Coffee?

Can curdled cream in your coffee make you sick?

This is the question that you must be having in your mind when you see your coffee with curdled cream.

There are two scenarios to think of when you search the answer for this question.

The first scenario is when you use coffee creamer that is expired or open for long period of time.

And you also use a milk in your coffee that is expired.

On the other side, the second scenario is when you use a healthy coffee creamer with natural ingredients and milk which is fresh to use.

In the first case scenario, the lactic acid in the cream increases due to long time exposure of the creamer with the open air.

And unintentional curdling of the expired milk combined with expired coffee creamer can definitely increase the chances of you getting sick.

So, the combined effect of expired milk, coffee creamer and higher acidity of the coffee when mixed together can definitely lead to your sickness.

Again, it may or may not make you sick which highly depends on how old your coffee creamer is, how spoiled your milk is and how much time both of them are exposed to open air.

In the second case scenario, it is perfectly fine to drink coffee even if it gets curdled with cream.

Because it can happen mainly due to the higher acidity of your coffee beans used in the coffee.

The coffee creamer and milk used in the second case are not expired or exposed to open air for long period and therefore using them in your coffee is perfectly safe for your health.

So, in this case using a low acid coffee will solve the issue of cream curdling.
