How long does almond milk last?

The shelf life of almond milk depends on whether it is store-bought or homemade, and whether it has been opened. Unopened shelf-stable carton almond milk lasts in the pantry until the expiration date printed on the package.

Once opened, store-bought refrigerated almond milk stays fresh for 7 to 10 days in the fridge. Homemade almond milk lacks preservatives and pasteurization, so it lasts only 3 to 5 days in the refrigerator. Signs of spoiled almond milk include curdling, a sour smell, unusual thickness, or a sharp, acidic taste. Discard immediately if spoilage appears.
