Almond milk needs refrigeration after opening, and any almond milk sold from the refrigerated case should stay refrigerated. Shelf-stable almond milk can usually be stored unopened in a cool pantry until the package date, but once opened it should be covered, refrigerated, and used according to the label.

How to Store Almond Milk
- Check whether the carton was sold shelf-stable or refrigerated.
- Keep shelf-stable cartons in a cool, dry pantry before opening.
- Keep refrigerated cartons cold from the time you buy them.
- After opening, close the carton tightly and refrigerate it promptly.
- Pour what you need into a glass instead of drinking from the carton.
- Follow the package instructions for how soon to use it after opening.
How to Tell If Almond Milk Is Bad
- Sour or fermented smell: discard it.
- Bloated or leaking carton: do not use it.
- Mold or unusual film: discard it.
- Thick, slimy, or ropey texture: discard it.
- Normal separation: some almond milk separates; shake only if it otherwise smells and looks normal.
Shelf-Stable vs Refrigerated Almond Milk
The key difference is packaging and processing. Shelf-stable cartons are made for unopened pantry storage. Refrigerated cartons are not. Once either type is opened, the storage rule changes: keep it cold, covered, and clean.
