- Storage Temperature: Almond milk should be stored in a cool, dark place, ideally in a refrigerator. High temperatures can accelerate spoilage.
- Packaging: Almond milk sold in Tetra Paks or cartons tends to have a longer shelf life than those packaged in plastic jugs.
- Processing: Almond milk that has been pasteurized will have a longer shelf life than unpasteurized varieties.

Under optimal storage conditions, unopened almond milk can typically last for:
- Unsweetened Almond Milk: 7-10 days in the refrigerator, up to 3 months in the freezer
- Sweetened Almond Milk: 5-7 days in the refrigerator, up to 2 months in the freezer
