Expiration & Storage Tips
When does oat milk expire?
Oat milk can last for about 7-10 days once opened and refrigerated properly. Unopened, commercially produced oat milk generally lasts for about 7-10 days past the date printed on the package when stored in a cool, dark area. If you're making your own oat milk, it will typically last for about 4-5 days in the fridge. If you decide to freeze your oat milk, it can extend its life to about 4-6 months. However, the texture might change once defrosted.
How do you tell if oat milk is bad?
Signs that your oat milk has turned or is starting to spoil include sour smell and taste, a change in color, or the presence of mold. It's also important to check the consistency. If the oat milk seems unusually thick or has lumpy curdles, it has probably gone off. It is recommended that you discard the entire milk if you notice any of these signs, even if some parts look okay. Spoiled oat milk can cause food poisoning.
Tips for storing oat milk to extend shelf life
• Store your oat milk in the refrigerator at temperatures below 40°F (4°C) once it has been opened. It should be sealed tightly to prevent bacterial growth.
• Unopened oat milk can be stored in a cool, dry, dark place like a pantry. However, once opened, always keep it in the fridge.
• If you're making your own oat milk, use a sterilized glass bottle for storage to minimize bacteria propagation.
• You can freeze oat milk to extend its shelf life. However, after defrosting, use it for cooking or baking rather than drinking it directly as the texture may change after freezing.
• Always handle oat milk with clean hands and utensils to prevent cross-contamination.
