Once opened, oat milk typically lasts for 7 to 10 days when stored properly in the refrigerator.
Understanding Oat Milk Shelf Life
The shelf life of oat milk can be a little confusing, as it varies depending on whether the container is unopened or has already been opened.
-
Unopened Oat Milk: Shelf-stable oat milk can last for several months, as indicated by the "best by" date on the packaging. It doesn't need to be refrigerated until opened.
-
Opened Oat Milk: Once opened, the clock starts ticking. Even though it was shelf-stable before, opened oat milk needs to be refrigerated and consumed within approximately 7 to 10 days for the best quality and to prevent spoilage.
Factors Affecting Oat Milk Shelf Life
Several factors influence how long your oat milk will remain fresh after opening:
-
Storage Temperature: Always refrigerate oat milk at a consistent temperature (ideally below 40°F or 4°C).
-
Hygiene: Avoid drinking directly from the carton, as this can introduce bacteria and shorten its lifespan. Pour what you need into a glass or container.
-
Manufacturing Process: Different brands and processing methods can affect the shelf life.
Signs of Spoilage
It's important to know how to identify spoiled oat milk:
- Smell: If the oat milk has a sour or off odor, it's likely spoiled.
- Appearance: Look for changes in texture or color, such as curdling or separation.
- Taste: If it tastes sour or otherwise unpleasant, discard it.
Tips for Extending Shelf Life
While you can't dramatically extend the 7-10 day window, these tips can help:
- Refrigerate immediately after opening. Don't leave it at room temperature for extended periods.
- Seal tightly. Ensure the container is properly sealed after each use.
- Store in the main compartment of the refrigerator, not the door, where the temperature fluctuates more.
- Consider smaller containers. If you don't use oat milk frequently, buying smaller containers can help prevent waste.
