Various companies provide different expiry dates depending on factors such as packaging and the ingredients used in manufacturing.

The 6 to 12 months are for milk stored in a pantry.

Oat milk has a refrigerated version with two to three weeks of shelf life.

The manufacturer in the packaging indicates the use-by date.

The milk stays goods for a maximum of 7 days past the expiry date.

The refrigerated milk must be kept chilled.

It is crucial to check which version of the oat milk you have.

Mistaking a refrigerated for the shelf-stable version will cost you dearly since it will expire faster than expected.

Once you open the shelf-stable oat milk, you must keep it refrigerated and have to take it within 5 to 10 days.

The milk packaging plays a significant role in preserving the milk because it keeps off light and bacteria, which contribute to milk going bad.

If you open the oat milk and leave it to sit out or without refrigeration, USDA recommends that you drink it within 2 hours, and if not, you should dispose of it.

After 2 hours, the milk may not indicate going bad, but it may result in adverse health impacts.

Such health impacts may be due to the growth of bacteria in the milk.

How to Tell if Oat Milk is Bad?

There are several ways that you can tell if oat milk is bad:

• First, you can tell by the expiry date. If the milk is past the expiry date by 4 months, it isn’t good, and you should not consume it. .
• Secondly, you can check whether the container is bloated. A bloated container indicates that there is a production of gas inside the container. Fermentation causes the production of carbon (IV) oxide gas that causes the packaging to swell. If the container is bloated, the milk is bad. .
• Thirdly, determine how long the milk has remained open. Milk that has stayed open for two weeks cannot be considered good even if refrigerated. Additionally, if the milk has been open for more than two hours and has not been refrigerated, it is likely bad. .
• Fourthly, smelling the milk is an excellent way of knowing whether it is bad. If you are used to fresh Oat milk, you understand how it smells – it has a pleasant smell. However, the milk has a foul, moldy, or sour smell when it is bad. .
• Check the color of the milk. Regular oat milk has a white or cream color that is consistent. If, after pouring it into a glass, you notice the dark or brownish color, the milk is bad. The presence of solid particles in the milk is also an indication that the milk is not good for consumption. .
• Finally, you can tell by the taste of the milk. The taste test should be the final one after all the other tests are negative. Most oat milk brands are sweet, and a sour taste clearly indicates that the milk is bad. .
