Sour Milk

Can you freeze sour milk? Sour milk is one of the most popular dairy products. It is used for cooking, baking or flavoring soups, but also as a dip or on baked potatoes. Thing is – there are some situations where you want to extend the shelf life of that dairy product. For example, you only use sour milk for cooking, you have a half-empty jug of it and you can’t find a way to use the rest of the product within the next few days. Or you have found a large supply of sour milk and would like to buy a few more containers of sour milk than usual. In both of these situations, freezing the sour milk seems to be the only solution. Like milk or yoghurt, sour milk canbe frozen. However, it is not recommended. There are a few more things to know about freezing sour milk.

How freezing affects sour milk

Freezing sour milk can extend its shelf life by 4 to 6 months. You can freeze this dairy product in its original container or in any other container. Please remember that the container should be airtight to prevent its contents from picking up other odors from the freezer. Similar to yogurt and milk, freezing sour milk affects its flavor and texture. When frozen, sour milk separates and its consistency changes significantly. After thawing, it resembles the consistency of cottage cheese. Unfortunately, in the case of sour milk, you cannot restore the texture of fresh sour milk by stirring and shaking the thawed product. These activities will help a little, but the texture will be significantly different than expected.

When to Consider Freezing Sour Milk?

As I mentioned before, the consistency of sour milk changes noticeably after freezing and thawing this dairy product. Fortunately, freezing sour milk is worth considering in some cases. Of course, frozen and thawed sour milk in its original form (eg, in a dip or on top of baked potatoes) will not suit your needs when you need sour milk in its original form. However, if you need this dairy for cooking or baking, or to stir it into a soup, frozen and then thawed curd should do the trick. If you are unsure whether the results will be satisfactory, you can perform a small test. Freeze a small amount of sour milk, thaw it again after a few days, add it to your dish and see how it tastes. If the taste is good, you can freely freeze sour milk for this purpose. If you want to extend the shelf life of this dairy product, try storing it upside down in the fridge. Many people claim that this greatly increases the shelf life of the liquid.


Sour milk is commonly used in cooking and baking. You can freeze sour milk, but it’s not recommended, and in most cases frozen and thawed sour milk won’t suit your needs.
