Can cashew milk go bad?

In this brief study, we will answer the question, “can cashew milk go bad?” Additionally, we will address the shelf life and storage characteristics of cashew milk.

Can cashew milk go bad?

Yes, cashew milk can go bad either beyond the expiration date or if it has spoiled due to improper handling.

How long can cashew milk last?

Generally, cashew milk – like with the vast majority of other nut milk – has a lengthy shelf life, especially when compared to dairy milk. Cashew milk will normally stay in the refrigerator for up to a week after it has been opened in most cases.

If you store carton milk on a regular shelf, it will have a long shelf life (thanks to the inclusion of stabilizers), and this will remain the case even if you store it in the refrigerator for many months. It has a longer shelf life than regular cashew milk.

It is more likely that fresh milk from the refrigerator or cold area would go bad sooner and will not last as long as the other, even when refrigerated. This is true for homemade nut milk as well, since the principle is the same: the absence of stabilizers or food additives results in a product with a constant shelf life.


If you store your cashew milk in the refrigerator (as recommended), it will last for an extended length of time.

Cashew milk that has not been opened, stabilized, or pasteurized will keep in the refrigerator for a long length of time. If stored at room temperature on standard shelves for 1-3 years, it should be safe to use. It would keep for a considerably longer time in the refrigerator.

Opened pasteurized cashew milk will also preserve for a long amount of time if kept in the refrigerator after opening. If you tightly close the container after each use and put it in the back of the refrigerator, it will last for many weeks without spoiling.

The most effective course of action is to examine the box itself and look for the ‘best by date on the label. This usually takes between two and three weeks.

You may keep fresh cashew milk refrigerated for up to a week after it has been opened as well. Once again, place it in the back of the refrigerator rather than on the door to keep it fresher for longer.


Although this is not always the case, the temperature in your pantry should be cooler than the surrounding environment. When stored at a lower temperature (about 5-10 C/41-50 F), the shelf life is substantially extended, almost as much as when stored in the refrigerator.

Keep in mind that this applies to cashew milk that has not been opened, whether it is pasteurized or unpasteurized.

If the container has already been opened, consume the contents within a week to guarantee that no stray bacteria or mold spores are introduced into the milk.

This is why it is essential to keep milk at a cool temperature in a container that is tightly closed and properly sealed. If you’ve run out of alternatives, you may wrap the milk in cling film or plastic wrap to keep it fresh.


Yes, it is feasible to make frozen cashew milk.

Additionally, it is possible to save it indefinitely as frozen food. The product will stay frozen in your freezer for as long as the machine is capable of freezing it if the product is not thawed and then frozen once again.

Depending on what you have on hand, we recommend freezing in freezer-safe containers or freezer-proof bags.

Indications that your cashew milk has gone bad

Although cashew milk does not deteriorate as quickly as dairy milk, there are a few signs that it has gone bad.

To begin with, if the milk is becoming older, the color will deepen and become yellow. There are many reasons for this, some of which include exposure to airborne pollutants and others which include the potential of bacterial contamination. Perhaps it would be wiser to toss it out.

It is also necessary to discard any milk that has developed mold on the container or inside its components. 

Third, an odd or strong odor is likewise not a good indicator of health, and the milk should be disposed of immediately. There is a faint fragrance of nuts in cashew milk, but it is not overwhelming and it does not have a sour or rotting taste.

It may be preferable to discard milk rather than risk anything if you are unclear when you bought the milk and if you cannot recall how long it has been opened.
